A private investigator stated that Whitney Houston was killed.
John Huebl purportedly found proof that reveals the musician was murdered by two men who were gathering a drug debt.
Houston purportedly due to pay £1.5 million to 'dangerous' drug traders before she was found deceased on Feb 11, 2012.
Huebl writes in the National Enquirer – via The Sun: "I have proof that points to Whitney being a victim of high-powered drug dealers who sent thugs to collect a huge debt she owed for drugs."
He added: "Whitney's body system reveals classic defense injuries that would have happened while she was fighting for her life."
Huebl says he has CCTV footage of the two alleged killers who had been trying to blend in with her entourage at the Beverly Hilton hotel, where she was found dead in a bathtub. He said that though the coroner stated there was no foul play, Houston had markings on her body which suggest otherwise.
In March, the Los Angeles County coroner's office revealed that Whitney Houston's cause of death was drowning combined with the "effects of atherosclerotic heart disease and cocaine use".
