The Los Angeles County Coroner's Office has begun issuing subpoenas and contacting doctors and pharmacies to obtain deceased singer Whitney Houston's medical and drug records, assistant chief coroner Ed Winter told TheWrap on Wednesday.
Winter added that this is standard operating procedure.
"We do that in most cases," Winter said.
A small assortment of medications were found in Houston's suite at the Beverly Hilton hotel following her Feb. 11 death, though nothing that would set off alarms: The anti-anxiety medicine Xanax, the painkiller ibuprofen, the menstrual cramp treatment Midol, and amoxicillin, which is used to treat bacterial infections, were reportedly found in the room, with the bottles containing few pills.
Winter confirmed to TheWrap that there were "not a lot" of pills found in Houston's room.
Even so, Houston's family was reportedly told that the "I Will Always Love You" singer likely died of a combination of prescription drugs and alcohol.
Houston, 48, was found "underwater and apparently unconscious" in the bathtub by a personal staff member Saturday afternoon, the Beverly Hills Police Department said Monday, but was removed from the tub before emergency responders arrived on the scene. Efforts to resuscitate her were unsuccessful, and Houston was pronounced dead at approximately 3:55 p.m.
The singer had a long struggle with substance abuse.
A cause of death has not yet been announced. A toxicology test is pending, though the results could take weeks to arrive.
Houston's funeral will take place Saturday at noon at the New Hope Baptist Church in Newark, N.J., which she attended as a child.
