Houston passed away on Saturday, after she was found unconscious and unresponsive in her hotel room at the Beverly Hilton. The award winning singer was declared dead by paramedics at the iconic hotel at 3:55 p.m. PST. She was 48.
The legendary singer's autopsy was conducted on Sunday, and Beverly Hills Police Department detectives were present during the examination.
"There were no physical signs of trauma on Whitney's body. She weighed over 150 pounds, and there was food in her stomach. Upon closer inspection of her throat, it did look enflamed, but nothing out of the realm of normal,” a source close to the situation tells RadarOnline.com. “Her heart wasn't enlarged which means she didn't have a pre-existing heart condition. Based on the condition of her body, and her coloring, Whitney might have been underwater for at least 30 minutes. Her face was blue/yellow when taken out of the bathtub where she was found.”
As RadarOnline.com previously reported, law enforcement found Valium, Lorazepam, and Xanax in Houston's hotel room.
The Grammy award winning singer had "a plethora of sedatives including Lorazepam, Valium, Xanax, and a sleeping medication that was found in her hotel room," a law enforcement source tells RadarOnline.com.
The prescription drugs were officially taken into custody by the Beverly Hills Police Department, who is handling the investigation.
Meanwhile, the Los Angeles County Coroner has authorized the release of Houston's body to her family for funeral arrangements.
