Lt. Mark Rosen said Wednesday that the determination was made after reviewing the Grammy-winning singer's full autopsy report, which attributed her death to accidental drowning. Coroner's officials ruled heart disease and cocaine use also contributed to the 48-year-old singer's death.
Houston died in a bathtub in the Beverly Hilton Hotel on Feb. 11 on the eve of the Grammy Awards. TMZ reported on Wednesday that it had obtained the 911 call placed after the singer had been discovered unresponsive in the tub. The website reported that in the call, a member of the Beverly Hilton security team is heard telling the 911 operator of a "46-year-old female found in the bathroom" who was not breathing. He never mentions Houston by name.
Police have repeatedly said they have found no signs of foul play in Houston's death.
Rosen extended condolences to Houston's family and fans. Houston had been planning a comeback, including a starring role in the remake of the film "Sparkle," which is due for release later this year.
