NBC NATIONAL NEWS — Late this afternoon, Thursday, March 22, the L.A. County Coroner released the official autopsy report for pop super-star Whitney Houston.
We’re told the troubled pop star accidentally drowned in a bathtub with cocaine and heart disease as contributing factors in her death.
The coroner ends weeks of speculation as to what killed the 48-year-old singer.
"We know that when she slipped under the water, she was still alive,” Craig Harvey, L.A. County spokesperson, explained. “We have evidence of water in the lungs, so that substantiates that finding."
Houston's body was found submerged in a bathtub by one of her staff members at the Beverly Hilton Hotel on Saturday, February 11 - one day before the Grammy's.
"They found her unresponsive,” Mark Rosen, BHPD, said. “They attempted life-saving resuscitation measures - unfortunately, they were not successful."
The coroner's report found no evidence of foul play, but did indicate results consistent with chronic cocaine use. The findings also showed marijuana, Xanax, the muscle relaxant Flexeril, and Benadryl in her system, but they did not contribute to her death.
Houston had planned to attend Clive Davis pre Grammy party the night she died.
Her death shocked and saddened the world.
Houston leaves behind her daughter Bobbi Kristina and a musical legacy that will forever be remembered.
