Whitney Houston was found face down in a bath of scalding water
The singer Whitney Houston was found face down in "extremely hot" water, according to the final coroner's report into her death released Wednesday.
The 41-page document confirmed the preliminary report released March 23 that the singer died from accidental drowning combined with the effects of heart disease and cocaine use, DPA reported.
The final verdict of the Los Angeles County coroner added that the singer's personal assistant found her face down under more than 30 centimetres of water and had burns on her body.
It also said a white crystalline powder was found in a spoon and on a mirror in the hotel room. The coroner did not test the powder, saying that was the responsibility of the police.
Houston was found dead February 11 in her suite at the Beverly Hilton Hotel in Beverly Hills, California, on the eve of the Grammy Awards.
While cocaine was found to have contributed to her death, numerous other drugs were also found in her body - including marijuana, Xanax and Benadryl - but did not contribute to her death, the coroner said.
"The other medications that were found were either in therapeutic or subtherapeutic levels and are not considered contributory to her death," coroner spokesman Craig Harvey said after the preliminary report in March.
Harvey said no alcohol was found in Houston's body. The latest report said an open champagne bottle was found in the room along with several bottles of prescription medication.
The autopsy results ended weeks of speculation over how the pop star who sang I Will Always Love You had died. Many had speculated that her well-documented troubles with drugs had caused her death at age 48.
