An autopsy on the singer was completed Sunday; however the coroner is not officially saying what killed the six-time Grammy winner.

Houston was found unresponsive Saturday afternoon by a family member in the bathtub of her fourth floor hotel room at the Beverly Hilton, according to Winter.

“She was underwater and apparently unconscious.  Ms. Houston was pulled from the tub by members of her staff and hotel security was promptly notified,” Beverly Hills police said in a statement.

Detective say Houston had been at the Beverly Hilton with a large entourage of family, friends and co-workers preparing for Clive Davis’ annual pre-award show bash at the same hotel.

Paramedics tried to revive the singer, but she was pronounced dead at 3:55 p.m.

The Beverly Hills Police Department has issued a security hold barring the coroner’s office from releasing details surrounding her death while toxicology tests continue.

However, the coroner’s office has said that there were no signs of foul play.

“At this time her cause of death is deferred and we are finishing with all of our testing and it will be an ongoing investigation,” said Assistant Chief Coroner Ed Winter.

Officials say it could take at least two weeks for toxicology findings to be returned, but a preliminary report could be available as soon as Wednesday.

“When we find out we will be in contact with the Beverly Hills Police Department and the family and give them the findings,” Winter said.

At a news conference Monday, Beverly Hills police said their investigation at the hotel was complete and stressed Houston’s death was not being handled as a homicide.

TMZ reports that officials told the singer’s family that Houston did not die from drowning but a combination of Xanax, other prescription drugs and alcohol.

The Los Angeles Times is reporting that police are interviewing family members to determine what Houston was doing Saturday hours before her death.

Houston’s daughter, Bobbi Christina Brown, 18, was rushed to Cedars Sinai Hospital Sunday where she was treated and released for anxiety and exhaustion, police said.

Houston’s ex-husband, Bobby Brown, who was preforming with New Edition in Mississippi when Houston died, issued a statement Sunday regarding her death.

“I am deeply saddened at the passing of my ex-wife, Whitney Houston. At this time, we ask for privacy, especially for my daughter, Bobbi- Kristina. I appreciate all of the condolences that have been directed towards my family and I at this most difficult time.” Said Bobby Brown.

The couple wed in 1992 and divorced in 2007 after a tumultuous marriage.

Funeral plans for the late singer have not been announced.

Fans have erected a make-shift memorial outside of the hotel, leaving notes, candles and flowers.

“It’s very sad, she’s gonna to be missed. We all loved her so much,” fan Shelia Johnson said.

A candlelight vigil will be held Monday at 5 p.m. in Leimert Park, 3415 W. 43rd. Place in Los Angeles.
