WWE icon Chyna's manager claims he knows how she died

According to the Los Angeles Times, Anthony Anzaldo, Laurer's manager, said she died of an accidental overdose of Valium and Ambien.

"It's a 98 percent certainty and 2 percent speculation," Anzaldo told The Associated Press on Wednesday.

Anzaldo reportedly found the star dead at her Redondo Beach, California, home April 20.

Laurer, who had a prescription for the tranquilizers and sleeping pills, had been taking the medications for three weeks, Anzaldo told the Times. However, she may have been "self-medicating a little bit more than she should have," he told the AP.

"They're not going to find, like, 60 pills in her stomach," said Anzaldo, who told the Times that he does not believe Chyna committed suicide.

The Los Angeles County coroner's office has not released an official cause of death because officials are still waiting for the results of toxicology tests, the AP reports.

Laurer's brain has been donated to Dr. Bennett Omalu, the subject of the film "Concussion" starring Will Smith, according to the AP.
