Cops: White powder found in Houston's room

Detectives found white powdery substances and a spoon with white residue in the hotel room where Whitney Houston died, according to the final autopsy report released Wednesday, The Associated Press reports.

Houston had cocaine throughout her system when she died, the report said, and a "spoon with a white crystal like substance in it, a rolled-up piece of white paper from off the top of a counter along the east wall of the bathroom" were found. The report does not specifically identify the substances as cocaine, although the drug was found in toxicology tests in Houston's heart and extremities.

Assistant Chief Coroner Ed Winter said he could not discuss how recently Houston may have used the drug.

Beverly Hills Police Lt. Mark Rosen said their investigation is still open and he could not comment on the findings.

On her final day alive, Houston complained of a sore throat, and an assistant suggested she take a bath before preparing for a pre-Grammy party, according to the report.

The Grammy-winning singer died Feb. 11 after drowning in a bathtub at the Beverly Hilton Hotel. Her death has been ruled as accidental and coroner's officials cited heart disease and cocaine use as contributing factors.
