LOS ANGELES ( AP) — Whitney Houston’s life was a doleful cover of other addiction riddled pop stars who put their talent and themselves at risk.

Her death has created more heartrending echoes of tragedies past: The painstaking investigation that follows the shocking loss. Why was Houston found underwater in a Beverly Hills hotel bathtub, beyond resuscitation?

The 48-year-old singer, who had prescription drugs in her room, left behind disconsolate family and friends and unfulfilled dreams. Her body was flown Monday by private jet to New Jersey, where she was born and where her funeral is being planned. Late Monday, a hearse under heavy police escort arrived at the Newark, N.J., funeral home that officials said was handling the arrangements for the late pop star.

After an autopsy Sunday, authorities said there were no indications of foul play and no obvious signs of trauma on Houston. It could be weeks, however, before the coroner’s office completes toxicology tests to establish the cause of death.

The singer had struggled for years with cocaine, marijuana and pills and her behavior had become erratic, including in the period before her death. Some described her as upbeat and eager to perform at producer Clive Davis’ pre-Grammy Awards bash. Others described an unfocused woman, unkempt and smelling of alcohol and cigarettes.
