Investigators looking into the death of Whitney Houston are reportedly now focusing on prescription medications found in the hotel room where she died.
The Los Angeles County Coroner tells CNN that authorities have been attempting to obtain Houston's medical records and determine the identity of her doctor. The Los Angeles Times quotes a source with knowledge of the case as saying that investigators are expected to subpoena doctors who prescribed her medications as well as the pharmacies where she obtained them.
The 48-year-old pop icon died Saturday at the Beverly Hills Hilton hotel just hours before she was to appear at producer Clive Davis' annual pre-Grammy Awards party. Ed Winter, assistant chief coroner for Los Angeles County, has said that although medication was found in the room, the amount was not unusually large.
An autopsy was conducted on Sunday, but no cause of death has been determined pending the results of toxicology reports that are expected to take several weeks. Authorities have said there were no indications of foul play and no obvious signs of trauma were found on Houston's body.
A private funeral service will be held for the superstar on Saturday in the Newark, New Jersey church where she first showcased her musical talent.
