Police conclude probe into Houston's death

Police close Houston investigation

Beverly Hills police say they have concluded Whitney Houston's death investigation and found no signs that a crime occurred, The Associated Press reports. Lt. Mark Rosen said Wednesday the determination was made after reviewing the Grammy-winning singer's full autopsy report, which attributed her death to accidental drowning. Coroner's officials ruled heart disease and cocaine use also contributed to the 48-year-old singer's death at the Beverly Hilton Hotel on Feb. 11. Police have repeatedly said they have found no signs of foul play in Houston's death.
