Teacher: Now, understand the problem? Solve this instance: Imagine if two of your loved ones were killed, and authorities knew it was murder but never caught or charged anyone with the crime. When a case goes cold many tend to loose hope, but a small lead decades later can crack a case back open. That's what happened when a former Sacramento man was arrested Dec.1 and charged with killing two people almost four decades ago. 
  
 75-year-old Silas Duane Boston was tracked down by the FBI and arrested in a Paradise convalescent home. Boston is accused of killing an English couple, Christopher Farmer and Peta Frampton in the summer of 1978. 
  
 Court documents show that the murder happened between June and July of 78' off the coast of Guatemala. Both Farmer and Frampton were tortured and hog tied and thrown in the middle of the ocean to drown. 
  
 Records show that Farmer and Frampton were once aboard the boat Boston owned and operated in Belize. Statements from Boston's two sons Vince and Russell stated that their father moved them from Sacramento to Belize running away from statutory rape charges. In interviews both boys said their dad illegally gave boat tours which is how they met the couple. 
  
 At the time of the murders Russell and Vince were 11 and 13 but during interviews this year they told an FBI agent they watched their father kill the couple. 
  
 This case was at a standstill for years until a Sacramento Police Officer was investigating the death of Silas Boston's former wife Mary Lou Boston. With the help of the FBI and Manchester England they began unraveling not only Mary Lou's disappearance but also the 38 year old maritime murders in the Caribbean Sea. These findings led to the federal charges and Boston's arrest. If he is found killed he will face life in prison or the death penalty. 
  
 Police also believe Boston might have killed another person in a fatal hit and run accident in 1972. 
  
 Copyright 2016 KXTV ||||| A federal judge announced a double murder indictment Thursday against a 75-year-old former Sacramento resident, 38 years after the hog-tied bodies of two British tourists were found after a boating excursion from Belize. 
  
 Silas Duane Boston, who was arrested last week in the rural town of Paradise, was charged with two counts of first-degree maritime murder in the killing of Christopher Farmer and his girlfriend, Peta Frampton. The tourists from Cheshire, England, recent graduates of medical and law schools who were both in their mid-20s, had taken an excursion on a boat that Boston was operating in Belize, earning money by taking tourists on scuba diving or snorkling expeditions. 
  
 Boston was brought into the courtroom Thursday in a wheelchair and fitted with audio headphones for the proceedings. He did not speak. His defense attorney, Douglas Beevers, said his client, who was living in a convalescent home when he was arrested, suffers from arthritis and has difficulty hearing. 
  
 “He didn’t receive all the batteries for his hearing aid, and it’s been difficult to communicate with him in jail,” Beevers said.

 Federal prosecutors announced they would not seek the death penalty against Boston, though the charges could result in life in prison. 
  
 A federal criminal affidavit in connection with the indictment stated that Boston, then 37, promised to take the couple to Mexico. But instead Farmer was beaten with a billy club, stabbed in the chest with a fillet knife and tied up after an apparent argument on the boat with Boston, who also tied up Frampton and then pushed them overboard, the FBI said. Their bodies were later found off the coast of Guatemala. 
  
 Boston was arraigned in Sacramento federal court Thursday before U.S. Magistrate Carolyn Delaney, who introduced a not-guilty plea on his behalf and scheduled his next court appearance for Jan. 10. The charges came after an unexpected break in a cold-case investigation involving the unsolved disappearance of Boston’s wife, Mary Lou Boston, who was last seen in 1968 in Sacramento – 10 years before Farmer and Frampton died – and is believed to have been shot and killed, according to court documents. 
  
 Interviewed by police as part of the missing person case, Boston’s son Vince described the incident that took place on the boat when he was 13 years old, according to court documents. 
  
 In a statement Thursday, Sacramento U.S. Attorney Phillip Talbert commended police agencies, including the FBI and the Greater Manchester Police Department of Great Britian, for helping bring the case forward. In particular, Talbert singled out the Sacramento police cold case investigators, saying: “Nothing would have happened if the Sacramento Police Department had not thought to consult with this office about what could be done with a 38-year-old homicide in the Caribbean Sea.” 
  
 The investigation has stirred a mystery over a deadly criminal saga potentially involving multiple victims. 
  
 According to a criminal complaint by FBI Special Agent David Sesma, a former traveling companion of Boston interviewed by authorities reported that Boston talked about killing two other tourists in Belize by taking them to an island in a rubber boat, robbing them, cutting their throats and leaving them in a jungle. The witness said Boston also claimed to have shot three drug dealers in Sacramento who assaulted a female friend. Federal authorities haven’t verified the reports. 
  
 The complaint also suggested Boston may have been involved in a fatal hit-and-run in Sacramento’s Lemon Hill neighborhood in 1972. 
  
 The same traveling companion also allegedly listened to Boston’s story about killing his wife. The FBI complaint says Boston told his traveling companion that he killed his wife and buried her body after taking her to an undisclosed location where he liked to go shooting. A man who traveled with Boston in Mexico told authorities that Silas Boston had said that after Mary Lou Boston exited his truck, he told her to run and then shot her. 
  
 Silas Boston told the man that he “was unsure if he hit her in the back of her skull or the base of her skull but the shot didn’t kill her,” the complaint states. The man said Boston told him he approached his wife as she pleaded for her life – asking “What about the kids?” – before Boston delivered the fatal shot. Authorities said Boston told the man that he was left with blisters on his hands from burying her. 
  
 According to a September 1968 missing person report filed with Sacramento police, a brother of Mary Lou Boston told authorities her disappearance seemed particularly strange, the report said, because “she was a devoted mother to her three children and could not stand to be away from the children for any period of time.” 
  
 The report said the brother told police that Boston, who was working for an ambulance company at the time, was acting uncharacteristically “nervous and jittery” and said he didn’t want to get involved if the brother contacted police. The report also noted that a .22 caliber rifle with a scope, said to be Boston’s favorite possession, was missing. Boston told the brother he had traded it “for some junk items he wanted,” the report said. 
  
 However, police investigators concluded at the time that Mary Lou Boston’s disappearance “does not appear to be a legitimate missing person” case because the couple “are having marital difficulties and “the wife has left the husband.” |||||

Nearly 40 years after he took a young British couple sailing on his boat, a California retiree has been charged with killing them, the Sacramento Bee reports. Prosecutors say Silas Duane Boston, 75, beat and hog-tied Christopher Farmer and girlfriend Peta Frampton aboard his boat in Belize before throwing them overboard 38 years ago. The Manchester couple were in their 20s and recent law and medical school graduates when they were killed, and their bodies were found floating off the coast of Guatemala in July 1978. Although the skipper was suspected in the deaths, investigators could not make the charges stick until they caught a break while looking into the 1968 disappearance of Boston's wife, Mary Lou. (Boston is alleged to have shot and killed her.) During an interview in that earlier case, Boston's son, Vince, revealed what happened aboard his dad's boat when he was 13 years old. His younger brother Russell was also aboard and implicated his father, reports ABC 10. Instead of taking the couple to Mexico, Boston, then 37, allegedly became enraged after an argument, beat and stabbed Farmer, then threw him and Frampton overboard after tying them up. If convicted, Boston faces life in prison. He was arrested earlier this month at the convalescent home where he lived, and appeared at his arraignment on double murder charges in a wheelchair. He did not speak. Boston is also suspected in other killings, prosecutors said. (Australian police have gotten a break in a 47-year-old cold case.)
