A Hollywood private investigator claims that he has found evidence that shows the late singer Whitney Houston was murdered.

Paul Huebl says that he has obtained video of Houston's killers than he plans to turn over to the FBI.

“I have evidence that points to Whitney being a victim of a high powered drug dealers who sent thugs to collect a huge debt she owed for drugs,” Huebl told the National Enquirer.

Houston died in February of an accidental drowning, according to the Los Angeles County coroner's office. Further examination indicated that the singer also suffered from a heart condition, atherosclerotic heart disease, and was found to have several drugs in her system at the time of her death, including cocaine, Benadryl, Xanax, marijuana and Flexeril.

Huebl suggested that Houston's death, while drug related, was precipitated by drug dealers attempting to collect money that they were owed, a supposed debt of up to $1.5 million.

According to Radar Online, Huebl has reviewed Houston's coroner’s report and gathered information from a network of drug informants that led him to the discoveries.

He noted that two men attempted to blend in to Houston's entourage at the Beverly Hills Hilton. Huebl claimed that Houston received a shipment of cocaine the day before she died and was heard lamenting about being harassed to pay her drug debt.

“I’m tired of this sh*t,” she supposedly said.

According to Huebl, there was a 45-minute window where Houston was alone on the day she died; at this time, her alleged attackers gained entry to her hotel room and were caught on surveillance video, he claimed.

He acknowledged that Houston's coroner’s report indicated no foul play; however, upon further review, Huebl claimed to have discovered notes that suggest otherwise.

“Whitney’s body shows classic defense wounds that would have occurred while she was battling for her life,” he told the Enquirer.

He claimed that the events occurred in her hotel room and bathroom, where a struggle ultimately ended her life.

The latest issue of the Enquirer hits newsstands on Thursday.
