What was his cause of death?
What was George Burn's cause of death?
When Burns turned 90 in 1986, the city of Los Angeles renamed the northern end of Hamel Road "George Burns Road." City regulations prohibited naming a city street after a living person, but an exception was made for Burns. In celebration of Burns' 99th birthday in January 1995, Los Angeles renamed the eastern end of Alden Drive "Gracie Allen Drive." Burns was present at the unveiling ceremony (one of his last public appearances) where he quipped, "It's good to be here at the corner of Burns & Allen. At my age, it's good to be anywhere!" George Burns Road and Gracie Allen Drive cross just a few blocks west of the Beverly Center mall in the heart of the Cedars-Sinai Medical Center. Burns remained in good health for most of his life, in part thanks to a daily exercise regimen of swimming, walks, sit-ups, and push-ups. He bought new Cadillacs every year and drove until the age of 93, when he stopped due to becoming so short that he couldn't see over the steering wheel. After that, Burns had chauffeurs drive him around. In his later years, he also had difficulty reading fine print. Burns suffered a head injury after falling in his bathtub in July 1994 and underwent surgery to remove fluid in his skull. Burns never fully recovered and all performances celebrating his 100th birthday were canceled. In December 1995, a month before his 100th birthday, Burns was well enough to attend a Christmas party hosted by Frank Sinatra (who turned 80 that month), where he reportedly caught the flu, which weakened him further. When Burns was 96, he had signed a lifetime contract with Caesar's Palace in Las Vegas to perform stand-up comedy there, which included the guarantee of a show on his centenary, January 20, 1996. When that day actually came however, he was too weak to deliver the planned performance. He released a statement joking how he would love for his 100th birthday to have "a night with Sharon Stone". His final public appearance was in at the MCG in Melbourne, Australia, where he opened the 1996 AFL Premiership Season on February 8. On March 9, 1996, 49 days after his centenary, Burns died in his Beverly Hills home at age 100. His funeral was held three days later at the Wee Kirk o' the Heather church in Forest Lawn Memorial Park Cemetery, Glendale. As much as he looked forward to reaching the age of 100, Burns also stated, about a year before he died, that he also looked forward to death, saying that on the day he would die, he would be with Gracie again in Heaven. Upon being interred with Gracie, the crypt's marker was changed from, "Grace Allen Burns-Beloved Wife And Mother (1902-1964)" to "Gracie Allen (1902-1964) & George Burns (1896-1996)-Together Again". George had said that he wanted Gracie to have top billing. CANNOTANSWER
Burns died in his Beverly Hills home at age 100.
George Burns (born Nathan Birnbaum; January 20, 1896March 9, 1996) was an American comedian, actor, singer, and writer. He was one of the few entertainers whose career successfully spanned vaudeville, radio, film, and television. His arched eyebrow and cigar-smoke punctuation became familiar trademarks for over three-quarters of a century. He and his wife, Gracie Allen, appeared on radio, television, and film as the comedy duo Burns and Allen.

At the age of 79, Burns had a sudden career revival as an amiable, beloved, and unusually active comedy elder statesman in the 1975 film The Sunshine Boys, for which he won the Academy Award for Best Supporting Actor. Burns, who became a centenarian in 1996, continued to work until just weeks before his death of cardiac arrest at his home in Beverly Hills.

Early life
George Burns was born Nathan Birnbaum on January 20, 1896 in New York City, the ninth of 12 children born to Hadassah "Dorah" (née Bluth; 1857–1927) and Eliezer Birnbaum (1855–1903), known as Louis or Lippe, Jewish immigrants who had come to the United States from Kolbuszowa, Galicia, now Poland. Burns was a member of the First Roumanian-American Congregation.

His father was a substitute cantor at the local synagogue but usually worked as a coat presser. During the influenza epidemic of 1903, Lippe Birnbaum contracted the flu and died at the age of 47. Nattie (as George was then called) went to work to help support the family, shining shoes, running errands, and selling newspapers.

When he landed a job as a syrup maker in a local candy shop at age seven, "Nate" as he was known, was "discovered", as he recalled long after:

One of the Burns Brothers' first regular gigs was operating the curtains at the vaudeville and nickelodeon theatre of Frank Seiden, father of Joseph Seiden, who would later become a Yiddish film producer. Burns started smoking cigars when he was 14.

Burns was drafted into the United States Army when the U.S. entered World War I in 1917, but he failed the physical because he was extremely near-sighted. To try to hide his Jewish heritage, he adopted the stage name by which he would be known for the rest of his life. He claimed in a few interviews that the idea of the name originated from the fact that two star major league players (George H. Burns and George J. Burns, unrelated) were playing major league baseball at the time. Both men achieved over 2,000 major league hits and hold some major league records. Burns also was reported to have taken the name "George" from his brother Izzy (who hated his own name so he changed it to "George"), and the Burns from the Burns Brothers Coal Company (he used to steal coal from their truck).

He normally partnered with a girl, sometimes in an adagio dance routine, sometimes comic patter. Though he had an apparent flair for comedy, he never quite clicked with any of his partners, until he met a young Irish Catholic lady in 1923. "And all of a sudden," he said in later years, "the audience realized I had a talent. They were right. I did have a talent—and I was married to her for 38 years."

His first wife was Hannah Siegel (stage name: Hermosa Jose), one of his dance partners. The marriage lasted twenty-six weeks and only occurred because her family would not let them go on tour unless they were married. They divorced at the end of the tour.

Burns's second wife and famous partner in their entertainment routines was Gracie Allen.

Stage to screen
Burns and Allen got a start in motion pictures with a series of comic short films in the late 1920s and early 1930s. Their feature credits in the mid- to late-1930s included The Big Broadcast (1932); International House (1933), Six of a Kind (1934), (the latter two films with W.C. Fields), The Big Broadcast of 1936, The Big Broadcast of 1937, A Damsel in Distress (1937) in which they danced step-for-step with Fred Astaire, and College Swing (1938) with Bob Hope and Martha Raye. Honolulu would be Burns's last film for nearly 40 years.

Burns and Allen were indirectly responsible for the Bob Hope and Bing Crosby series of "Road" pictures. In 1938, William LeBaron, producer and managing director at Paramount, had a script prepared by Don Hartman and Frank Butler. It was to star Burns and Allen with Bing Crosby, who was then already an established star of radio, recordings and films. The story did not seem to fit the comedy team's style, so LeBaron ordered Hartman and Butler to rewrite the script to fit two male co-stars: Hope and Crosby. The script was titled Road to Singapore, and it made motion picture history when it was released in 1940.

Radio stars

Burns and Allen first made it to radio as the comedy relief for bandleader Guy Lombardo, which did not always sit well with Lombardo's home audience. In his later memoir, The Third Time Around, Burns revealed a college fraternity's protest letter, complaining that they resented their weekly dance parties with their girl friends listening to "Thirty Minutes of the Sweetest Music This Side of Heaven" had to be broken into by the droll vaudeville team.

In time, though, Burns and Allen found their own show and radio audience, first airing on February 15, 1932, and concentrating on their classic stage routines plus sketch comedy in which the Burns and Allen style was woven into different little scenes, not unlike the short films they made in Hollywood. They were also good for a clever publicity stunt, none more so than the hunt for Gracie's missing brother, a hunt that included Gracie turning up on other radio shows searching for him as well.

The couple was portrayed at first as younger singles, with Allen the object of both Burns's and other cast members' affections. Most notably, bandleaders Ray Noble (known for his phrase, "Gracie, this is the first time we've ever been alone") and Artie Shaw played "love" interests to Gracie. In addition, singer Tony Martin played an unwilling love interest of Gracie's, in which Gracie "sexually harassed" him, by threatening to fire him if the romantic interest was not reciprocated.

In time, however, due to slipping ratings and the difficulty of being portrayed as singles in light of the audience's close familiarity with their real-life marriage, the show adapted in the fall of 1941 to present them as the married couple they actually were. For a time, Burns and Allen had a rather distinguished and popular musical director: Artie Shaw, who also appeared as a character in some of the show's sketches. A somewhat different Gracie also marked this era, as the Gracie character could often be found to be mean to George.

George: Your mother cut my face out of the picture.
Gracie: Oh, George, you're being sensitive.
George: I am not! Look at my face! What happened to it?
Gracie: I don't know. It looks like you fell on it.

Or

Census Taker: What do you make?
Gracie: I make cookies and aprons and knit sweaters.
Census Taker: No, I mean what do you earn?
Gracie: George's salary.

As this format grew stale over the years, Burns and his fellow writers redeveloped the show as a situation comedy in the fall of 1941. The reformat focused on the couple's married life and life among various friends, including Elvia Allman as "Tootsie Sagwell," a man-hungry spinster in love with Bill Goodwin, and neighbors, until the characters of Harry and Blanche Morton entered the picture to stay.

Like The Jack Benny Program, the new George Burns & Gracie Allen Show portrayed George and Gracie as entertainers with their own weekly radio show. Goodwin remained, his character as "girl-crazy" as ever, and the music was now handled by Meredith Willson (later to be better known for composing the Broadway musical The Music Man). Willson also played himself on the show as a naive, friendly, girl-shy fellow. The new format's success made it one of the few classic radio comedies to completely re-invent itself and regain major fame.

Supporting players
The supporting cast during this phase included Mel Blanc as the melancholy, ironically named "Happy Postman" (his catchphrase was "Remember, keep smiling!"); Bea Benaderet (later Cousin Pearl in The Beverly Hillbillies, Kate Bradley in Petticoat Junction and the voice of Betty Rubble in The Flintstones) and Hal March (later more famous as the host of The $64,000 Question) as neighbors Blanche and Harry Morton; and the various members of Gracie's ladies' club, the Beverly Hills Uplift Society. One running gag during this period, stretching into the television era, was Burns's questionable singing voice, as Gracie lovingly referred to her husband as "Sugar Throat." The show received and maintained a Top 10 rating for the rest of its radio life.

New network
In the fall of 1949, after 12 years at NBC, the couple took the show back to its original network CBS, where they had risen to fame from 1932 to 1937. Their good friend Jack Benny reached a negotiating impasse with NBC over the corporation he set up ("Amusement Enterprises") to package his show, the better to put more of his earnings on a capital-gains basis and avoid the 80 percent taxes slapped on very high earners in the World War II period. When CBS executive William S. Paley convinced Benny to move to CBS (Paley, among other things, impressed Benny with his attitude that the performers make the network, not the other way around, as NBC chief David Sarnoff reputedly believed); Benny in turn convinced several NBC stars to join him, including Burns and Allen. Thus, CBS reaped the benefits when Burns and Allen moved to television in 1950.

Television

On television, The George Burns and Gracie Allen Show put faces to the radio characters audiences had come to love. A number of significant changes were seen in the show:
A parade of actors portrayed Harry Morton: Hal March, The Life of Riley alumnus John Brown, veteran movie and television character actor Fred Clark, and future Mister Ed co-star Larry Keating.
 Burns often broke the fourth wall, and chatted with the home audience, telling understated jokes and commenting wryly about what show characters were doing or undoing. In later shows, he would actually turn on a television and watch what the other characters were up to when he was off-camera, then return to foil the plot.
 When announcer Bill Goodwin left after the first season, Burns hired announcer Harry Von Zell, a veteran of the Fred Allen and Eddie Cantor radio shows, to succeed him. Von Zell was cast as the good-natured, easily confused Burns and Allen announcer and buddy. He also became one of the show's running gags, when his involvement in Gracie's harebrained ideas would get him fired at least once a week by Burns.
 The first shows were simply a copy of the radio format, complete with lengthy and integrated commercials for sponsor Carnation Evaporated Milk by Goodwin. However, what worked well on radio appeared forced and plodding on television. The show was changed into the now-standard situation comedy format, with the commercials distinct from the plot.
 Midway through the run of the television show the Burns's two children, Sandra and Ronald, began to make appearances: Sandy in an occasional voice-over or brief on-air part (often as a telephone operator), and Ronnie in various small roles throughout the 4th and 5th seasons. Ronnie joined the regular cast in season 6. Typical of the blurred line between reality and fiction in the show, Ronnie played George and Gracie's on-air son, showing up in the second episode of season 6 ("Ronnie Arrives") with no explanation offered as to where he had been for the past five years of the show. Originally his character was an aspiring dramatic actor who held his parents' comedy style in befuddled contempt and deemed it unsuitable to the "serious" drama student. When the show's characters moved back to California in season 7 after spending the prior year in New York City, Ronnie's character dropped all apparent acting aspirations and instead enrolled in USC, becoming an inveterate girl chaser.

Burns and Allen also took a cue from Lucille Ball and Desi Arnaz's Desilu Productions and formed a company of their own, McCadden Corporation (named after the street on which Burns's brother lived), headquartered on the General Service Studio lot in the heart of Hollywood, and set up to film television shows and commercials. Besides their own hit show (which made the transition from a bi-weekly live series to a weekly filmed version in the fall of 1952), the couple's company produced such television series as The Bob Cummings Show (subsequently syndicated and rerun as Love That Bob); The People's Choice, starring Jackie Cooper; Mona McCluskey, starring Juliet Prowse; and Mister Ed, starring Alan Young and a talented "talking" horse. Several of their good friend Jack Benny's 1953–55 filmed episodes were also produced by McCadden for CBS as well.

The George Burns Show
The George Burns and Gracie Allen Show ran on CBS Television from 1950 to 1958, when Burns at last consented to Allen's retirement. The onset of heart trouble in the early 1950s had left her exhausted from full-time work and she had been anxious to stop, but could not say "no" to Burns.

Burns attempted to continue the show (for new sponsor Colgate-Palmolive on NBC), but without Allen to provide the classic Gracie-isms, the show expired after a year.

Wendy and Me
Burns subsequently created Wendy and Me, a sitcom in which he co-starred with Connie Stevens, Ron Harper, and J. Pat O'Malley. He acted primarily as the narrator, and secondarily as the adviser to Stevens' Gracie-like character. The first episode involved the nearly 70-year-old Burns watching his younger neighbor's activities with amusement, just as he would watch the Burns and Allen television show while it was unfolding to get a jump on what Gracie was up to in its final two seasons. Again as in the Burns and Allen television show, George frequently broke the fourth wall by commenting directly to viewers. The series only lasted a year. In a promotion, Burns had joked that "Connie Stevens plays Wendy, and I play 'me'."

The Sunshine Boys
After Gracie's death in 1964, George immersed himself in work. McCadden Productions co-produced the television series No Time for Sergeants, based on the hit Broadway play; George also produced Juliet Prowse's 1965–66 NBC situation comedy, Mona McCluskey. At the same time, he toured the U.S. playing nightclub and theater engagements with such diverse partners as Carol Channing, Dorothy Provine, Jane Russell, Connie Haines, and Berle Davis. He also performed a series of solo concerts, playing university campuses, New York's Philharmonic Hall and winding up a successful season at Carnegie Hall, where he wowed a capacity audience with his show-stopping songs, dances, and jokes.

In 1974, Jack Benny signed to play one of the lead roles in the Metro-Goldwyn-Mayer film version of Neil Simon's The Sunshine Boys (Red Skelton was originally the other, but he objected to some of the script's language). Benny's health had begun to fail, however, and he advised his manager Irving Fein to let longtime friend Burns fill in for him on a series of nightclub dates to which Benny had committed around the U.S.

Burns, who enjoyed working, accepted the job for what would be his first feature film appearance for 36 years. As he recalled years later:
 "The happiest people I know are the ones that are still working. The saddest are the ones who are retired. Very few performers retire on their own. It's usually because no one wants them. Six years ago Sinatra announced his retirement. He's still 

Ill health had prevented Benny from working on The Sunshine Boys; he died of pancreatic cancer on December 26, 1974. Burns, heartbroken, said that the only time he ever wept in his life other than Gracie's death was when Benny died. He was chosen to give one of the eulogies at the funeral and said, "Jack was someone special to all of you, but he was so special to me ... I cannot imagine my life without Jack Benny, and I will miss him so very much." Burns then broke down and had to be helped to his seat. People who knew George said that he never could really come to terms with his beloved friend's death.

Six weeks before filming started, Burns had triple bypass surgery.

Burns replaced Benny in the film as well as the club tour, a move that turned out to be one of the biggest breaks of his career; his wise performance as faded vaudevillian Al Lewis won him the 1975 Academy Award for Best Supporting Actor, and permanently secured his career resurgence. At the age of 80, Burns was the oldest Oscar winner in the history of the Academy Awards, a record that would remain until Jessica Tandy won an Oscar for Driving Miss Daisy in 1989.

Oh, God!
In 1977, Burns made another hit film, Oh, God!, playing the omnipotent title role opposite singer John Denver as an earnest but befuddled supermarket manager, whom God picks at random to revive his message. The image of Burns in a sailor's cap and light springtime jacket as the droll Almighty influenced his subsequent comedic work, as well as that of other comedians. At a celebrity roast in his honor, Dean Martin adapted a Burns crack: "When George was growing up, the Top 10 were the Ten Commandments".

Burns appeared in this character along with Vanessa Williams on the September 1984 cover of Penthouse magazine, the issue which contained the notorious nude photos of Williams, as well as the first appearance of underage pornographic film star Traci Lords. A blurb on the cover even announced "Oh God, she's nude!"

Oh, God! inspired two sequels Oh, God! Book II (in which the Almighty engages a precocious schoolgirl played by Louanne Sirota to spread the word) and Oh, God! You Devil—in which Burns played a dual role as God and the devil, with the soul of a would-be songwriter (played by Ted Wass) at stake.

Later films
After guest-starring on The Muppet Show and Alice, Burns appeared in 1978's Sgt. Pepper's Lonely Hearts Club Band, the film based on The Beatles' album of the same name. In 1979, at the age of 83, Burns starred in two feature films, Just You and Me, Kid and Going in Style. Burns remained active in films and TV past his 90th birthday. One of his last films was 1988's 18 Again!, based on his half-novelty, half-country music-based hit single, "I Wish I Was 18 Again". In this film, Burns played an 81-year-old self-made millionaire industrialist who switched bodies with his awkward, artistic, 18-year-old grandson (played by Charlie Schlatter).

Burns also did regular nightclub stand-up acts in his later years, usually portraying himself as a lecherous old man. He always smoked a cigar onstage and reputedly timed his monologues by the amount the cigar had burned down. For this reason, he preferred cheap El Producto cigars as the loosely wrapped tobacco burned longer. Burns once quipped "In my youth, they called me a rebel. When I was middle-aged, they called me eccentric. Now that I'm old, I'm doing the same thing I've always done and they're calling me senile."

Arthur Marx estimated that Burns smoked around 300,000 cigars during his lifetime, starting at the age of 14. In his final years, he smoked no more than four a day and he never used cigarettes or marijuana, claiming "Look, I can't get any more kicks than I'm getting. What can marijuana do for me that show business hasn't done?" His last feature film role was the cameo role of Milt Lackey, a 100-year-old stand-up comedian, in the 1994 comedy mystery Radioland Murders.

Final years and death

Burns was still appearing at major hotel/casinos in Las Vegas, Reno, and Lake Tahoe during the early 1980s. When Burns turned 90 in 1986, the city of Los Angeles renamed the northern end of Hamel Road "George Burns Road." City regulations prohibited naming a city street after a living person, but an exception was made for Burns. In celebration of Burns's 99th birthday in January 1995, Los Angeles renamed the eastern end of Alden Drive "Gracie Allen Drive." Burns was present at the unveiling ceremony (one of his last public appearances) where he quipped, "It's good to be here at the corner of Burns & Allen. At my age, it's good to be anywhere!" George Burns Road and Gracie Allen Drive cross just a few blocks west of the Beverly Center mall in the heart of the Cedars-Sinai Medical Center.

Burns remained in good health for most of his life, in part thanks to a daily exercise regimen of swimming, walks, sit-ups, and push-ups. He bought new Cadillacs every year and drove until the age of 93. After that, Burns had chauffeurs drive him around. In his later years, he also had difficulty reading fine print.

Burns suffered a head injury after falling in his bathtub in July 1994 and underwent surgery to remove fluid in his skull. Burns never fully recovered and his performing career came to an end. In February 1995, Burns, in what would be his final television appearance, was presented with the very first SAG Lifetime Achievement Award by the Screen Actors Guild. In December of that year, a month before his 100th birthday, Burns was well enough to attend a Christmas party hosted by Frank Sinatra (who turned 80 that month), where he reportedly caught the flu, which weakened him further. When Burns was 96, he had signed a lifetime contract with Caesars Palace in Las Vegas to perform stand-up comedy there, which included the guarantee of a show on his centenary, January 20, 1996. When that day actually came, however, he was too weak to deliver the planned performance. He released a statement joking how he would love for his 100th birthday to have "a night with Sharon Stone."

On March 9, 1996, 49 days after his centenary, Burns died in his Beverly Hills home. His funeral was held three days later at the Wee Kirk o' the Heather church in Forest Lawn Memorial Park Cemetery, Glendale. As much as he looked forward to reaching the age of 100, Burns also stated, about a year before he died, that he also looked forward to death, saying that on the day he would die, he would be with Gracie again in Heaven. Upon being interred with Gracie, the crypt's marker was changed from, "Grace Allen Burns—Beloved Wife And Mother (1902–1964)" to "Gracie Allen (1902–1964) & George Burns (1896–1996)—Together Again". George had always said that he wanted Gracie to have top billing.

Legacy

George Burns has three stars on the Hollywood Walk of Fame: a motion pictures star at 1639 Vine Street, a television star at 6510 Hollywood Boulevard, and a live performance star at 6672 Hollywood Boulevard. The first two stars were placed during the initial installations of 1960, while the third star ceremony was held in 1984, in the new category of live performance, or live theatre, established that year. Burns is also a member of the Television Hall of Fame, where he and Gracie Allen were both inducted in 1988.

He is the subject of Rupert Holmes's one-actor play Say Goodnight Gracie.

R. v. Smithers, [1978] 1 S.C.R. 506 is a leading Supreme Court of Canada decision on determining criminal causation in an offence of manslaughter. The Court held that the Crown must show that the accused's acts were a "contributing cause of death outside of the de minimis range." In practice, this test applied to all criminal offences requiring proof of causation.

Background
On February 18, 1973, Smithers, a black teen, played in a hockey game against a team including Barrie Cobby, a white teen, in a Mississauga rink. During the game, Smithers was subject to numerous racial slurs by Cobby. Evidence given by numerous witnesses at the trial indicated both had a dislike for each other's behaviour and Cobby had often been using racial slurs toward Smithers. During their final game, Cobby was given a penalty for spearing Smithers during the game while Cobby was in the penalty box Smithers scored a goal and laughed in Cobby's direction. Cobby shouted further racial slurs and Smithers threatened Cobby that he was going to "get him" if Cobby did not apologize for making the ongoing racial insults.

After the game Smithers waited outside the rink for Cobby to leave. When Cobby came out Smithers chased him and was grabbed by at least 3 of Cobby's friends, Smithers grabbed Cobby's jacket and  kicked Cobby once in the stomach area. Immediately Cobby fell to the ground and started to gasp for air. Cobby soon passed out and died shortly afterwards. It was discovered that he died from inhaling vomit after being kicked due to a rare condition in which his epiglottis failed. Although Smithers was unsure if the kick even landed (there were no marks on Cobby), he was still responsible. 

Smithers was charged for manslaughter under section 205 of the Criminal Code (now section 222) for "caus[ing] the death of a human being". In his defence, Smithers argued that it was the epiglottis condition that caused death, not the blow.

The issue before the Supreme Court was whether the kick was a sufficient cause of the death to attract criminal liability.

A unanimous Court held that Smithers was guilty of causing death of a human being. The decision was written by Justice Dickson.

Opinion of the court
Dickson adopted the comments of G. Arthur Martin from a 1943 case note on the English Larkin case, where it was stated that "[t]here are many unlawful acts which are not dangerous in themselves and are not likely to cause injury which, nevertheless if they cause death, render the actor guilty of culpable homicide ... In the case of so-called intentional crimes where death is an unintended consequence the actor is always guilty of manslaughter at least."

The question Dickson considered was what degree of causation is required to prove guilt. Where consequences need not be intended such as manslaughter, he proposed the degree of contribution to the cause of death need only pass a de minimis test. That is, the Crown need only show that the amount contributed to the cause of death be more than trivial. 

Dickson also reaffirmed the application of the thin skull doctrine in homicide, where the fact that Cobby was susceptible to failure of the epiglottis should not absolve Smithers from liability. Consequently, since the kick may have killed Cobby, its contribution to his death was more than trivial and so Smithers is criminally liable.

 Władysław Sikorski (62), prime minister of the Polish Government in exile, was among 16 people killed on 4 July 1943 when their plane crashed into the sea shortly after taking off from the Royal Air Force base at Gibraltar Airport. The plane had not managed to gain sufficient altitude due to its elevators being prevented from working properly; British investigators found the cause was most likely an accident while their Polish counterparts called it undetermined. The bodies of Sikorski's daughter, chief of staff and other key aides purportedly on the plane were never found, and the plane's only survivor, the pilot, had uncharacteristically worn his life preserver in the cockpit. Sabotage and a possible assassination have been suspected, with Nazi Germany, the Soviet Union, the United Kingdom, or even rival factions in the Polish government in exile theorized to have been involved. Poland reopened the case in 2008; an exhumation of Sikorski's body found his injuries consistent with death from an air crash, ruling out some theories that he had been killed before being put on the plane, but the investigators still could not rule out the possibility of sabotage. British files on the case will remain sealed until 2050.

Their bluish pallor and the presence of vomit and excrement led to a finding that they had been poisoned, but the coroner was unable to determine what the toxin was. It was suspected they had been murdered (possibly by Chandler's husband) although no suspect has ever been identified. A 2006 TV documentary suggested their deaths were not due to foul play but the result of hydrogen sulfide gas leaking from the river bed and reaching dangerously high concentrations in the low-lying depressions where their bodies were found.

Newton suggested that Frey may have been shot by his partner; there has been no new investigation to determine whether this was the case and whether this was an accident.

At first ruled to have died of influenza following a brief hospitalization on 19 March, suspicions were aroused when her body was released to the funeral home and embalmed before a legally required autopsy could be carried out. Despite the compromised evidence, three autopsies, all with their own irregularities, were performed and her husband John eventually became the only person indicted by a Texas grand jury for murder by omission, or failing to take proper action in the face of a life-threatening situation. The first attempt to prosecute him ended in a mistrial in 1972; he was murdered before he could be retried and the gunman who was suspected of his murder died in a police shootout. Two other alleged accomplices were later convicted.

Decomposition was too advanced to determine how Wiltsey had died. Suspicion accumulated around Lodzinski in later years due to reports that she had changed her account of his disappearance several times shortly after reporting it, and her conviction for an attempt to stage her own kidnapping in 1994 followed by another conviction for theft several years later. In 2014 she was arrested for her son's murder and convicted after trial two years later, but the state Supreme Court vacated that conviction in 2021 for insufficient evidence.

In 2000, a skull fragment belonging to his daughter Camille was found while some bone fragments of Dr Godard were discovered six years later in the English Channel. No trace of his son or his wife (the latter did not go on the sailing trip and stayed at home) has ever been found, nor has any trace of the boat. However, investigators found traces of blood in the family home and in Godard's caravan, raising suspicion that Godard's wife was murdered. In 2012, the case was closed without charges. Prosecutors ruled out accidental death and believe that Dr Godard probably murdered his family before committing suicide at sea, but they also acknowledge that they are not certain of this.

 Rodney Marks (32), an Australian astrophysicist, died of a sudden illness on 12 May 2000 at Amundsen–Scott South Pole Station in Antarctica. It was not possible for his body to be flown to New Zealand and autopsied until after the Antarctic winter ended six months later; the cause of death was found to have been methanol poisoning. Suicide was ruled out, as he did not seem to have a motive and had readily sought treatment for his apparent illness, nor did an accidental overdose seem likely, either, as there was plenty of alcoholic drink available for consumption at the base should he have wanted it. The New Zealand police believed instead that the methanol had been "unknowingly" introduced into Marks' system but could not conclusively call the case a homicide. Further investigation has been frustrated by the refusal of American agencies to share their findings, the global dispersal of researchers and personnel at the base that winter, the 2006 disappearance of the doctor who treated Marks, and the loss of any possible crime-scene evidence during the winter after Marks' death.
 Soad Hosny (58), was an actress from Cairo, Egypt, who died after in London after she mysteriously fell from the balcony of her friend's apartment on 21 June 2001.
 On 11 August 2001, Irish musician Paul Cunniffe (40), formerly of the bands Blaze X and the Saw Doctors, died in a fall in the London neighborhood of Whitechapel.

 Tempe Girl is the name given to an unidentified decedent whose body was discovered on 27 April 2002 in Tempe, Arizona. She had died of cocaine intoxication – ruled to be neither an accident nor a homicide – one day before the discovery of her body. She is believed to have been of either Hispanic or Native American ethnicity and was allegedly picked up while hitchhiking, claiming she had been effectively disowned by her own mother for her frequent recreational drug use.
 Abu Nidal (65), Palestinian terrorist leader behind the 1985 Rome and Vienna airport attacks, already suffering from leukemia, was reported to have died from a gunshot wound in Baghdad on 16 August 2002. Iraq's government at the time claimed his death was a suicide; the Fatah Revolutionary Council Nidal founded claimed he was assassinated on Saddam Hussein's orders to prevent his possible capture during the American invasion of Iraq that began six months later.
 Jeremiah Duggan (23), a British student studying in Paris, was found dead on a highway in Wiesbaden, Germany, early on 27 March 2003. The initial investigation concluded he had committed suicide by running into traffic. However, his mother, noting that he had called her in great distress over his involvement with the LaRouche movement, who may have discovered that he was British and Jewish, within an hour of his death, never accepted that theory, and a later investigation found evidence that the accident may have been staged to cover an earlier beating. The case was reopened in 2012 after extensive litigation in England, resulting in a change of the cause of death to "unexplained", with the note that Duggan may have been involved in some sort of "altercation" beforehand.

A human skull that was found off Vanikoro in April 2003 was thought to been that of Gaspard Duché de Vancy (35–36), who disappeared in 1788. Who it belonged to and it's death cause are unknown.
 Jürgen Möllemann (57), German Free Democratic Party politician, died on 5 June 2003 in a parachuting incident at Marl-Lohmühle. His death was investigated by the Essen district attorney's office, which published a final report on 9 July 2003. While outside interference was ruled out, no definite verdict was reached on whether Möllemann committed suicide or had died via misadventure. Shortly before his death, Möllemann, a passionate and experienced skydiver, had been confronted with allegations he had been involved in illegal arms deals and evaded taxes on millions of euros he allegedly earned from these activities. To enable a full investigation on these charges, the Bundestag lifted his parliamentary immunity on 5 June 2003 at 12:28, 22 minutes before his death. The tax evasion charges were dropped after his death.
 Singer-songwriter Elliott Smith (34), died of stab wounds inflicted in his Los Angeles home on 21 October 2003. His girlfriend claims she got out of the shower after an argument, having heard him scream, to find him with the knife sticking out of his chest, and found a short suicide note on a Post-It shortly thereafter. While he did indeed have a history of depression and drug addiction, friends say he was actively working to finish an album at the time and seemed optimistic. The coroner found the stab wounds were inconsistent with a suicide attempt but could not say it was a homicide either; the cause of the stabbing remains undetermined and has not been further investigated.
 Jonathan Luna (38), an assistant U.S. attorney from Baltimore, was found dead of multiple stab wounds inflicted with his own penknife in Denver, Pennsylvania, on the morning of 4 December 2003, in a stream underneath his car, which had been driven there overnight from Baltimore. The FBI, which has jurisdiction over the possible murder of any U.S. federal employee, found that Luna had mounting financial problems and was facing an investigation over missing money at his office, considered it a suicide or botched attempt at staging a kidnapping. However, the Lancaster County coroner's office, pointing to evidence suggesting he had been abducted and someone else was driving for at least the final stage of his drive, ruled it a homicide and considers the case open.
 Lamduan Armitage was a formerly unidentified woman whose body was discovered in 2004 on the mountain Pen-y-ghent in Yorkshire, England, leading her to become known as the Lady of the Hills. The woman was found to have originally come from somewhere in South-East Asia, but despite an international police investigation, the identity of the woman, and how she arrived at the location remained a mystery until 2019. The woman was identified in March 2019 through DNA testing. Her cause of death remains unknown.
 Alonzo Brooks (23), American man who went missing from La Cygne, Kansas on 3 April 2004 and was found dead about a month later on 1 May 2004. After the pathologists did an autopsy they have not yet been able to tell the cause of his death.
 The coroner investigating the death of Richard Lancelyn Green (51), a British Arthur Conan Doyle scholar who was found garrotted with a shoelace on his bed in his home on 27 April 2004, returned an open verdict. Many of his friends and family suspected homicide as he had complained of someone following him in his efforts to stop the auction of a cache of Doyle's personal papers that he believed to have been wrongfully acquired. However, despite suicide by garrotte being unusual and difficult, some investigators believed that he had followed the example of one of Doyle's Sherlock Holmes stories in which a woman stages her suicide to look like a murder.
 John Garang (60), Sudanese politician and former rebel revolutionary leader, died on 30 July 2005 in New Cush, Sudan in a suspicious helicopter crash.

 Joyce Carol Vincent (38), was found dead in her London flat in January 2006, two years after she had died, by which time the body had decomposed so much as to make identifying a cause of death impossible; her story was profiled in the 2011 documentary Dreams of a Life.
 Rey Rivera (32), American writer who was working for Stansberry and Associates who went missing from his house on 16 May 2006 and was found dead on Belvedere Hotel on 24 May 2006, in Mount Vernon, Baltimore Even though the Baltimore Police Department has claimed that his death was most likely to be a suicide, this has not been proven to be the case.
 Bob Woolmer (58), Pakistan's national cricket coach, was found dead in his hotel room on 18 March 2007, after losing in the Cricket World Cup 2007 in the West Indies. Investigators at first ruled the death a suicide, but the jury that heard the inquest returned an open verdict.
 Three years after the body of Corryn Rayney (44), was found in the Perth suburb of Kings Park, Western Australia a week after her 7 August 2007 disappearance, her husband Lloyd was charged in her murder even though a cause of death had not been determined. A judge acquitted him at his 2012 trial, finding the largely circumstantial case was further compromised by police misconduct. The verdict was upheld on appeal the following year; Rayney and his lawyers have called for two known sex criminals to be investigated as well.
 The Salish Sea human foot discoveries are the severed feet found from 20 August 2007 to 1 January 2019 that are known to belong to people who are thought to be dead. The circumstances behind these events remain unclear.
 Two-year-old Caylee Anthony, of Orlando, Florida, was reported missing by her grandmother in the summer of 2008, when she learned that her daughter Casey had not seen her in over a month. Casey claimed the girl had been kidnapped by a nanny and circumstantial evidence led to her arrest on murder charges that fall. A tip that could have led to the body's discovery in August was not fully acted upon until December; by then the body was so decomposed that it was impossible to establish how Caylee had died, although the coroner ruled it homicide. Casey Anthony, despite public sentiment strongly against her, was acquitted of the murder and child-abuse charges (but convicted of the lesser charges of lying to the police) after a heavily covered trial in 2011, where her lawyer claimed that Caylee had accidentally drowned in the family pool and Casey's domineering father had led a cover-up. Later, her father came forward with his own explanation: Casey had allegedly been known to drug Caylee to entice her to sleep so Casey could leave Caylee home alone and go out with friends for the evening. He alleges Casey or a friend accidentally overdosed Caylee, killing her, and in a panic, made up the kidnapping story as a cover.
 American guitarist Hiram Bullock (52), died on 25 July 2008 of an undetermined cause. While it was known that he had tongue cancer and was still in treatment, he was believed to have completely recovered from the disease, which is why some sources dispute cancer as the cause of death and suggest that he died as a result of his drug addiction problems.
 American professional wrestler Steven James Bisson (32), who went by the ring name of "Steve Bradley" was found dead on 4 December 2008 in Manchester, New Hampshire in a parking lot across the street from a pro wrestling school in where he once operated. Bradley's cause of death is undetermined, as the autopsy could not reveal what he died from, so his death remains a mystery.
 The Peter Bergmann case is an unsolved mystery pertaining to the death of an unidentified man in County Sligo, Ireland, whose naked body was found on a beach; the autopsy found no signs of drowning or foul play and thus the cause of death remains undetermined. From 12 to 16 June 2009, a man using the alias "Peter Bergmann" visited the coastal seaport town of Sligo in northwest Ireland. He used this alias to check into the Sligo City Hotel, where he stayed during the majority of his visit, and was described by hotel staff and tenants as having a heavy German accent. Despite conducting a five-month investigation into the death of "Peter Bergmann", the Garda Síochána have never been able to identify the man or develop any leads in the case.
 Skeletal remains found in a dry creek bed in California's Malibu Canyon on 9 August 2010, turned out to be those of Mitrice Richardson (25). She had last been seen on the night of 16 September 2009 in the backyard of a former local television news anchor, after being arrested for marijuana possession and failure to pay the bill at a local restaurant where she had been acting strangely, behavior that investigating officers did not believe was caused by alcohol or drugs. The coroner has said her death did not appear to be a homicide, but the body was too decayed to determine the exact cause of death.

2010–2019
 On 23 August 2010, the partially decomposed body of Gareth Williams (32), a Welsh mathematician who worked for British intelligence GCHQ, but who was seconded to MI6 at the time of his death, was found in a padlocked bag in the bathroom of a safe house in the London neighbourhood of Pimlico. It was determined he had been dead for about a week. Due to the nature of his work, the investigation had to withhold details of it and some other aspects from any material made public; his family and friends allege that the Metropolitan Police compromised and mishandled key forensic evidence in the early stages of their response. An initial investigation by the coroner's office concluded that the death was a homicide; a later re-investigation by the police claimed that it was instead an accident.
 Rajiv Dixit (43), an Indian public speaker and social activist who died on 30 November 2010 in Bhilai, Chhattisgarh, after his meal was poisoned. It is claimed that Dixit refused to undergo emergency medical treatment, as he did not trust Allopathic medicine, and died shortly thereafter. No autopsy was ever conducted so it remains unknown whether Dixit was deliberately poisoned, committed suicide, or if a person or persons covered up the truth.
 British citizen Lee Bradley Brown (39), was arrested by Dubai police while on holiday there 6 April 2011 and charged with assault after an incident between him and a hotel maid; accounts of the circumstances differ. Held without bail, he died in custody six days later after, police claimed, being beaten by cellmates; later they said he had "thrown himself on the ground repeatedly." An autopsy, however, found instead that Brown had, under the influence of hashish, choked on his own vomit. British officials who were allowed to examine the body disputed that conclusion, saying they saw no evidence of choking or blunt force trauma; Dubai authorities have declined repeated requests to share evidence such as CCTV footage from the original incident and the police station that might clarify matters. A coroner's inquest in the UK that considered only the autopsy report and the diplomats' reports returned an open verdict.
 Tom J. Anderson (35), formerly known by his birth name "Ahmad Rezaee" was a businessman and the eldest son of Iranian Major General Mohsen Rezaee. On 12 November 2011, he was found dead in the Gloria Hotel, located in Dubai Media City where he was staying. There are different theories about how he died, yet the cause of his death remains unknown.
 Stephen Corrigan (48), an Irish man who disappeared on 22 November 2011, and on 9 April 2020 some remains of his skeleton were found in Rathmines, Dublin. Corrigan's death cause is unknown.
 Candice Cohen-Ahnine (35), a French Jewish woman who successfully fought a legal battle against Saudi prince Sattam bin Khalid Al Saud over their illegitimate daughter, fell to her death in Paris on August 16, 2012. Her death is considered suspicious in nature due to the circumstances.
 Exiled Russian oligarch Boris Berezovsky (67), was found dead in his home near Ascot, Berkshire on 23 March 2013. At first glance he had hanged himself; he had recently lost what remained of his fortune, and some other close friends had unexpectedly died, which had left him despondent. The police soon ruled the case a suicide, but at the inquest, Berezovsky's daughter, who believes her father was murdered at the behest of the Russian government, introduced a report by a German pathologist that cast enough doubt for the coroner to return an open verdict.
 A worker at a Fenton, Missouri, senior living facility found the body of Shirley Rae Neumann, 78, on the grounds outside the facility on the afternoon of October 31, 2013. At first it appeared that Neumann, who suffered from advanced arthritis and dementia, had fallen from the balcony of her apartment, since its railing had been broken, and the county coroner ruled the death accidental. But tests also found a level of the sedative Zolpidem in her blood that was eight times higher than a normal dose would have left. The last person to see Neumann alive was her daughter, Pam Hupp. Hupp told staff that her mother would not be leaving her apartment the next day, and stood to benefit financially from her mother's death. Hupp had also pleaded guilty to another murder that prosecutors alleged she had committed to point suspicion at the husband of a murdered friend of Hupp's who had been acquitted at a retrial after spending several years in prison, a murder in which Hupp herself has been implicated as the real killer. After these events, a new coroner changed the finding to undetermined.
 On 15–16 November 2013, skeletal remains of two adults and child were found in a field outside Red Oak, Oklahoma. A year later they were identified as the Jamison family, who had gone missing in 2009 while looking into some land they wanted to purchase. Their abandoned pickup truck was three miles (4.8 km) from where their bodies were found. No cause of death has been determined.
 The decomposing remains of Canadian journalist Dave Walker (57), were found in Cambodia's Angkor temple complex on 1 May 2014, ending a search that began shortly after he failed to return to his hotel's guest house on the night of 14 February. While the medical examiner concluded that he had died weeks earlier, the cause of Walker's death could not be determined.
 Bone fragments found along the Rio Culebra near Boquete, Panama, in late June 2014 were matched to Lisanne Froon, 22, and Kris Kremers, 21, of Amersfoort, the Netherlands. The two had last been seen alive on 1 April when they went for a hike on the popular El Pianista trail. After unsuccessful initial searches a backpack belonging to the women was turned in by a local. It contained their phones, a Canon camera and personal effects. After two months small fraction of their remains was found as well. The women's cell phones showed that they had repeatedly attempted to contact emergency numbers shortly after taking pictures of themselves at the Continental Divide. Those calls had continued over several days, and Froon's camera contained 90 photographs taken in the night of 8 April, seven days after their disappearance. Most of the photos showed the jungle in the dark, but some of them contained rock formations, and small pieces of paper and other items in close-up and one contained the back of Kremers's head. It was impossible to determine from the remains that were found exactly how they had died. Local officials believe the women suffered an accidental injury shortly after getting lost in a network of trails in the region's cloud forests and got lost in the wilderness around Volcán Barú; however, Panamanian lawyers for their families have pointed to failings of the investigation and suggested both women could have met with foul play.
 On 27 June 2014, the body of Andrew Sadek (20), was recovered from the Red River near Breckenridge, Minnesota, with a small-caliber gunshot wound and a backpack full of rocks. He had last been seen by a security camera leaving his dorm at North Dakota State College of Science in Wahpeton around 2 a.m. on 1 May. At the time of his disappearance he had been working as a confidential informant for local police as a result of his own arrest for selling marijuana on campus, which could otherwise have resulted in a long prison sentence. It has not been determined yet whether his death was suicide or murder. Like Rachel Hoffman's death, the case has been used as an example of the mishandling of youthful CIs by police.
 Gennadiy Tsypkalov (43), was a political and military figure of the unrecognized Luhansk People's Republic (LPR). According to officials of the Luhansk People's Republic, Tsypkalov had committed suicide on 17 May 2014, yet according to some of Tsypkalov's colleagues whom Igor Plotnitsky dismissed, the leadership of LPR murdered Tsypkalov. His true death cause is unknown.

The bodies were in an upstairs bedroom where a fire had been set; they were found with multiple stab wounds. An original ruling of murder-suicide was changed to undetermined in 2017 after a court challenge by the couple's sons, motivated by complaints of mishandled evidence and some evidence suggesting the couple had been attacked by an intruder. The sons are currently calling for the investigation to be reopened.

 Alberto Nisman (51), an Argentine federal prosecutor, was found dead in his apartment of a single gunshot wound to the head on 18 January 2015. He had been investigating the 1994 AMIA bombing, Argentina's deadliest terror attack, and had publicly accused President Cristina Kirchner and other high officials close to her of covering up for suspects in the case for foreign-policy reasons; he was scheduled to present these allegations to Congress the next day. While some of the circumstances of his death are consistent with an early statement that he committed suicide, friends and relatives say that he was eagerly looking ahead to his appearance before Congress and did not seem depressed or despondent at all. Kirchner has suggested the country's intelligence services were behind the killing, since he was about to expose their attempts to bring her down, and called for them to be dismantled. The case remains under investigation.
 Canserbero (26), a Venezuelan hip hop artist and songwriter, was found dead from an apparent fall in front of his apartment complex in Maracay on January 20, 2015. Several hypotheses have been proposed as to what led to his death.
 Kayla Mueller (26), an American human rights activist and humanitarian aid worker who had been taken captive by the Islamic State in August 2013 in Aleppo, Syria, where she was helping Doctors Without Borders, was reported to have died in a Jordanian air strike during the Syrian Civil War in Raqqa on 6 February 2015. Her death was confirmed by the Pentagon, but the circumstances could not be established by the US. The Pentagon agreed the building she supposedly died in according to ISIS was hit in the bombings, but disputed that Mueller or any other civilian had been inside at the time. The site had been bombed by the coalition twice before, and was targeted again because ISIS soldiers sometimes return to bombed sites, thinking the coalition would not bomb those sites again, according to Pentagon spokesman John Kirby. After Abu Bakr al-Baghdadi's death in October 2019, new speculations arose that Al-Baghdadi may have had her executed.
 On 22 April 2015, the body of Ambrose Ball (30), of London, was recovered from the River Lea in Tottenham. He had last been seen leaving his vehicle following a single-car accident early on the morning of 24 January after visiting a local pub with friends. The body was too decomposed to determine a cause of death; police requested an adjournment of the inquest in order to further investigate, implying a murder charge was in the works. No charges were ever filed, and threats were later made against Ball's friends and family after they set up a Facebook page appealing for help from the public and questioning the conduct of the investigation.
 On 8 February 2016, an unidentified bus driver was purportedly killed by a falling meteorite in Tamil Nadu, India. If the object truly was a meteorite, then it would be first human fatality to such a type of death in recorded history.

High-ranked member of ruling SNS of Aleksandar Vučić, from 2010 to 2014, and later dissident. He disappeared in 2017, allegedly fleeing to the United States, however, in March 2021 Serbian media published a document in which the Public Prosecutor of the Higher Public Prosecutors Office in Belgrade states that the Prosecutor's Office issued an order ordering the payment of costs to the Institute for Forensic Medicine of the Faculty of Medicine, University of Belgrade for the autopsy of Vladimir Cvijan's body on 20 November 2018 in Belgrade, Serbia. The cause, circumstances and exact date of his death are still unknown.

 Computer hacker Adrian Lamo (37), was found dead 14 March 2018 on a pile of sheets in the guest bedroom of the Wichita, Kansas, home of a couple he had been living with. After three months of investigating, the county coroner was unable to identify a cause of death. While there are some alternative theories suggesting his death had something to do with his controversial involvement in the criminal cases against Chelsea Manning and Julian Assange, the most likely theory is the possible adverse interactions of some of the medicines found near him with Kratom, which he often used.
Jeffrey Epstein, found dead in his cell, the official cause was suicide by hanging but speculation that he was murdered by powerful figures prevails.
 Hong Kong teenager Chan Yin-lam, who participated in the 2019 Hong Kong protests, was found dead and naked in the harbour off Tseung Kwan O on 22 September 2019.

Some other accounts, however, have him being killed by his own side to prevent his capture during an attack by Czech resistance fighters; others suggest those accounts of his death were put out to cover his surrender to the U.S. Army, in whose custody he supposedly hanged himself two years later.
