Whitney Houston died from drowning in a hotel bathtub, but coroner’s officials said Thursday that heart disease and chronic cocaine use were contributing factors to the singer’s death.  The release of the autopsy ends weeks of speculation about what killed the Grammy-winning singer on February 11, 2012.

Houston was found submerged in the bathtub of her room at the Beverly Hilton Hotel and her death has been ruled as accidental. Prescription medications were found in her hotel room, but coroner’s officials said they weren’t in excessive quantities.

Beverly Hills police said in a statement there was no evidence of wrongdoing in connection with Houston’s death.
