 Whitney Houston was murdered by drug dealers and a new surveillance video proves it, a Hollywood private investigator is claiming 
  
 Paul Huebl says he has turned over evidence to the FBI that shows the 48-year-old singer was killed over a drug debt in February. 
  
  
  
 The medical examiner ruled that she drowned in her bathtub at the Beverly Hilton hotel after taking a cocktail of cocaine, marijuana and several legal drugs. 
  
  
  
 Case closed: The Los Angeles County Coroner ruled Whitney Houston's death an accidental drowning after she was found dead in her bathtub 
  
 Tragedy: The 48-year-old singer's body is carried to a hearse after her funeral in Newark, N.J., in February 
  
 The National Enquirer is reporting that Huebl believes the troubled star was targeted by several 'high powered drug dealers who sent thugs to collect a huge debt she owed for drugs.' 
  
 She owed $1.5million to dealers, according to some reports. 
  
 However, Huebl told MailOnline that he doesn't know for certain that Houston was killed - only that evidence he collected could point in that direction. 
  
  
  
 He says that the star received a delivery of cocaine to her room the day before her death and could be heard saying, 'I'm tired of this sh*t.' 
  
 He says the Houston had previously been subjected to harassment by dealers trying to collect on her debt. 
  
  
  
 Tragic: The troubled star had a potent cocktail of cocaine, marijuana and prescription drugs in her system when she died at the Beverly Hilton hotel 
  
 Huebl says he obtained surveillance video that shows two unknown men who repeatedly went to the Beverly Hilton and integrated themselves into Houston's entourage. 
  
  
  
 Private investigator: Paul Huebl, the man who is making the claims about Houston's death, is a former police officer who became an actor 
  
 The private investigator claims these are the men who may have slipped into Houston's hotel room and killed her. 
  
  
  
 He also disagrees with the Los Angeles County Coroner's ruling that the star's death was 'accidental.' 
  
  
  
 'Whitney’s body shows classic defense wounds that would have occurred while she was battling for her life,' he said. 
  
 However, Huebl conceded that the marks on her hands and fingernails could have been obtained in some other ways and that they were only 'suspected' defensive wounds. 
  
  
  
 The private investigator said he also has evidence that Houston's hotel room was ransacked, showing further hints of a violent struggle. 
  
 Huebl says he gave his evidence to the Chicago field office of the FBI in the hopes that the agency will open a criminal investigation. 
  
 ' I think that if you put all these things together, they do kind of spell homicide, with a big red capital "H,"' he told MailOnline. 
  
  
  
 The FBI did not immediately respond to requests for comment. A message left with Beverley Hills police was not immediately returned. 
  
  
  
 Heubl, a former Chicago police officer who became an actor after he retired, says he conducted the investigation after being hired by a client who did not believe the official reports on Houston's death. 
  
 He believes Beverley Hills police did not fully investigate Houston's death because they did not want to bring the negative attention to Beverly Hills or to the Beverly Hilton. 
  
  
  
 Huebl would not say who hired him.

 A leading private investigator has unearthed bombshell new evidence that tragic diva WHITNEY HOUSTON was murdered – and he’s taking it to the FBI to get the case reopened. 
  
 The ENQUIRER has learned exclusively that Paul Huebl, a former Chicago police investigator and now a top Hollywood private eye, plans to pres­ent his secret dossier to the bureau’s Chicago office – revealing shocking evidence that details who killed Whitney and why. 
  
 In a sensational disclosure that can crack the case wide open, Huebl says he’s received a tip from knowledgeable sources that Whitney’s killers are actually caught on hotel videotape, and he’s contacting FBI agents to take a fresh look at the case he believes local authorities bun­gled or covered up. 
  
 “I have evidence that points to Whitney being a victim of high-powered drug dealers who sent thugs to collect a huge debt she owed for drugs,” Huebl told The ENQUIRER. 
  
 The veteran investigator believes he is close to learning the identity of the vicious killers. 
  
 He says they are two men from a group of scruffy hangers-on – unknown by Whitney’s usual en­tourage – who kept showing up in the days before the singer’s untimely death at age 48. 
  
 His confidential informants insist that close examination of the surveillance videos from the Bev­erly Hilton hotel, where Whitney died, will show two shadowy characters entering and leaving her suite right around the time she died. 
  
 Ever since America’s greatest female singer was found floating face-down in a scalding-hot bathtub on Feb. 11, 2012, Huebl has relentlessly gone after her suspected killers.

A:
The National Enquirer claims to have a big scoop: Whitney Houston was murdered. It spoke to former Chicago cop/California private eye Paul Huebl, who says there is evidence that just such a crime occurred. "Knowledgeable" sources told him that Houston was done in by "high-powered drug dealers who sent thugs to collect a huge debt she owed for drugs"—and that the two killers were captured by the Beverly Hilton's video surveillance. He plans to take his evidence, which currently does not include said killers' identities, to the FBI. Huebl tells the Daily Mail that Houston's body "shows classic defense wounds that [could] have occurred while she was battling for her life" and that he has evidence her room was ransacked. The Mail adds that Houston's alleged debt was rumored to be $1.5 million.
