With the official cause of Whitney Houston's death now released -- accidental drowning due to atherosclerotic heart disease and cocaine use -- a new TMZ report says someone may have removed all traces of cocaine from Whitney's hotel room as a way to hide evidence.
The L.A. Coroner's Office said in their report Whitney used cocaine "immediately prior to her collapse." But investigators who arrived on scene found no traces of the white powder or any other illegal substance.
One source extremely close to the situation told TMZ that the individual who removed the cocaine was also the person who supplied it to the pop singer.
The Beverly Hills PD told TMZ the investigation is not closed, but said in a previous statement there was no evidence of wrongdoing.
Houston was found dead in a bathtub at the Beverly Hilton Hotel last month, and several pills were found on the scene -- including Xanax, muscle relaxants and Benadryl.
