The Los Angeles County Coroner's office is going to be obtaining copies Whitney Houston's medical records in their ongoing investigation to determine her official cause of death, RadarOnline.com is exclusively reporting.
Houston died in her room at the Beverly Hilton Hotel Saturday afternoon. Responding emergency medical personnel declared the singer dead at approximately 3:55 pm PST. She was 48.
As RadarOnline.com previously reported, Whitney was seen leaving a doctor's office three times between February 2 and February 10. Houston was reportedly seeing a ear, nose and throat doctor, and several other physicians.
L.A. County Assistant Chief Coroner Chief Ed Winter will be going to Houston's doctors' offices to get copies of her medical charts.
"Winter will get copies of the medical charts from all of her treating physicians. He needs all of that information for Whitney's final autopsy report. It will be a very thorough and extensive report, and Winter will go where the facts take him. The cops and coroner already have several prescription bottles that were recovered from her hotel room. The doctors listed on those bottles will be contacted as well, and some of these doctors are out of state," a law enforcement source told RadarOnline.com exclusively.
Houston had "a plethora of sedatives including Lorazepam, Valium, Xanax, and a sleeping medication that was found in her hotel room," a source tells us.
The prescription drugs were officially taken into custody by the Beverly Hills Police Department, who is handling the investigation, and the autopsy took place on Sunday. Cops will be working with the Coroner's office to determine the official cause of the pop singer's death, but that could take weeks.
