LOS ANGELES — Officials investigating the death of Whitney Houston are trying to determine whether she drowned in a bathtub shortly before she was set to attend a pre-Grammy Awards gala.
A member of Houston's entourage found her unresponsive Saturday afternoon in her suite at the Beverly Hilton Hotel and called authorities. Beverly Hills Fire Department paramedics performed CPR for about 20 minutes before declaring her dead.
It will be weeks before investigators determine an official cause of death. The Los Angeles County Coroner's Office said it performed an autopsy Sunday but deferred any findings until toxicology results are available in six to eight weeks.
The Los Angeles Times reported that unnamed sources who were briefed on the inquiry said drowning is one of several scenarios investigators are exploring. The sources stressed that authorities still have many unanswered questions, particularly about what Houston was doing in the hours before her death. They are also interviewing friends and family members to determine whether Houston had any underlying medical conditions, said the sources, who spoke to the Los Angeles Times on the condition of anonymity because the case was ongoing.
One source with knowledge of the case said that although Houston was found in the bathtub, officials are still unsure whether she died of natural causes or was in some other way stricken.
Houston struggled with drug and alcohol abuse for years, and in May her spokeswoman said the singer was going back into rehab.
Houston was in Beverly Hills for music industry titan Clive Davis' annual pre-Grammy party Saturday night at the Beverly Hilton. Over the last few days, she had made several public appearances. At times she had been acting strangely, skipping around a ballroom and reportedly doing handstands near the hotel pool. Houston greeted people with a warm smile but at times appeared disheveled in mismatched clothes and hair that was dripping wet.
On Thursday, Houston dropped by the rehearsals for the event, where journalists — including a Los Angeles Times reporter — were in attendance. A Grammy staffer said that as reporters interviewed Davis and singers Brandy and Monica, Houston was dancing just off camera to make the singers and Davis laugh. Grammy personnel expressed concern that she would be caught on camera, and that reporters would write about her behavior.
Beverly Hills police officials, who are investigating the case in conjunction with the coroner's office, said Saturday night that it's far too early to determine whether drugs or alcohol played any role in Houston's death. Police said there is no indication of foul play but placed a security hold on her Coroner's Office file, which is common in high-profile cases.
Lt. Mark Rosen said Houston was at the hotel with a large entourage of family, friends and co-workers, some of whom helped identify her body after she was declared dead.
On Sunday morning, Houston's daughter, Bobbi Kristina Brown, was rushed by ambulance from the hotel to nearby Cedars-Sinai Medical Center, police said. Details of her medical problem were not available, but she was reportedly released from the hospital a few hours later.
The hotel was also besieged by fans who assembled a makeshift memorial of flowers, candles and notes for Houston.
