Houston drowned accidentally at the Beverly Hilton Hotel on Feb. 11, and autopsy results revealed heart disease and her recent and chronic cocaine use were contributing factors.
The results ended weeks of speculation about what killed the singer-actress at age 48 on the eve of the Grammy Awards and a planned comeback. Instead, Houston now joins the long list of entertainers who have died early with drugs at least partly to blame.
Coroner’s officials did not reveal how much cocaine was found in Houston’s system, but said there were signs of recent and chronic use. It was unclear whether she suffered a heart attack before drowning, Assistant Chief Coroner Ed Winter said.
