New evidence has been unearthed surrounding Whitney Houston’s unexpected death in February this year.

Private investigator Paul Huebl claims that he has uncovered evidence that shows that the star had been involved with drugs and eventually falling victim to debt collectors. The PI said toThe National Inquirer: “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.” According to him, the singer owed money in excess of $1.5million to dealers before her death. The detective claims that he has CCTV footage, pointing to Whitney having been attacked by two men, as well as a coroner’s report which shows evidence of a struggle, prior to the singer’s death.

None of this evidence has been confirmed as valid thus far, but Huebl has said that he is turning all of his leads, collected through a network of informants, over to the FBI in an effort to resolve the case once and for all. After Houston was found dead in the bathtub of her hotel room on February 12th, 2012, the coroner’s report showed large traces of cocaine in her blood and her death was attributed to a chronic substance abuse and heart problems. Whether Huebl’s claims will shed any new light on the case, remains to be seen.
