The Los Angeles County Coroner's office has released an initial autopsy report for Whitney Houston's death, saying the singer drowned after collapsing in the bathtub following a possible heart attack.
Toxicology tests revealed Houston had cocaine in her system and that she had used the drug "in the time period just immediately prior to her collapse."
Many have wondered if those around her and in her entourage played a part in Houston’s drug problem. Bobby Brown's sister, Leolah Brown, suggested singer and record producer Ray J was to blame for Houston's death, because he was enabling her cocaine use. But Ray J has denied her claims, saying he had no idea Houston was even doing drugs at the time of her death.
