Whitney Houston was found dead in the bathtub of her Beverly Hilton hotel in LA on February 11, the eve of the Grammy Awards.
The cause of death is yet to be confirmed, pending toxicology reports, although today, Radar reported Whitney Houston had a deadly mixture of Valium, Xanax and alcohol in her system when she was found at the Beverly Hilton.
“Whitney had taken Valium, Xanax, and alcohol, which led to her death,” a source close to the situation tells RadarOnline.com. The coroner is waiting on final toxicology results to determine which one of the three was the major contributing factor of her demise.
“The coroner will be closely examining Whitney’s blood alcohol content at the time she died as well. The sedatives and alcohol will almost certainly be the cause of death, and not drowning.
“Her heart stopped beating because her respiratory system was suppressed because of the anti-anxiety meds, and combined with the booze it probably happened very quickly before she was found partially submerged in the bathtub,” they said.
The final toxicology results for Whitney Houston should be released in the next several weeks.
