Whitney Houston drowned face down in a tub of "extremely hot water" about 12 inches deep, the final autopsy report on the singer's death said.

The Los Angeles County coroner ruled that Houston's February 11 death was an accidental drowning with the "effects of atherosclerotic heart disease and cocaine use" as contributing factors.

The coroner's report stopped short of detailing what happened to Houston, but HLN's Dr. Drew Pinsky, an addiction medicine specialist, examined the autopsy report for CNN and suggested she might have suffered a seizure brought on by the use of cocaine possibly combined with a withdrawal from alcohol and a prescription sedative.
