Beverly Hills: Police have closed their investigation into Whitney Houston's death without finding evidence to suggest it was anything other than an accidental drowning, investigators have announced. The Beverly Hills Police Department did not release a detailed report on the case, but Lt Mark Rosen yesterday said the conclusion came after detectives reviewed the complete findings of the coroner's office.
Coroner's officials ruled Houston drowned accidentally at the Beverly Hilton on February 11 and that heart disease and cocaine use contributed to her death.
Houston's death on the eve of the Grammy Awards stunned the world. The singer had been attempting a comeback and had finished work on a remake of the film 'Sparkle.'

Houston\'s death sparked a renewed interest in her music and movies, sales of which will benefit her only daughter.
Toxicology results showed cocaine in her body, and coroner's officials said the results indicated chronic use. In the bathroom, investigators found a small spoon described by investigators as having a 'crystal-like substance' in it, and
they discovered a white powdery substance in a drawer, a coroner's report released last week showed.
Houston had a history of drug abuse which marred her career, robbing her of her voice and reputation, but family and friends described her as intent on returning to glory in the months before her death.
Her death at age 48 sparked a renewed interest in her music and movies, sales of which will benefit her only daughter, Bobbi Kristina.
