Chyna had been taking the legally prescribed pills over the course of three weeks, but wasn't using them properly, he said.

 “She was inappropriately taking her legally prescribed medication over the course of two to three weeks,” Anzaldo said. “On Sunday night, her body had enough.” 
  
 The manager doesn’t believe that Chyna had purposely taken a deadly number of pills in a suicide attempt, as there weren’t any illegal drugs or alcohol around the apartment when he found her. 
  
 Chyna had been taking Ambien and Valium for years, but had steadily upped her intake to a dangerous amount, leading up to her death, Anzaldo said. 
  
 “Her normal amount was one thing, but over the course of time she was increasing, and not properly,” he told the News.

 Chyna’s toxicology report will not return for another eight months, but her manager predicted the prescription drugs would be behind the wrestler’s death. 
  
 “They’re not going to find 60 pills in her stomach,” Anzaldo explained.

 The 45-year-old wrestling star, had been dead for days before Anzaldo found her body on April 21. 
  
 Her brain will be turned over to the doctor played by Will Smith in “Concussion,” to examine for any signs of chronic traumatic encephalopathy (CTE). 
  
 Anzaldo claimed Chyna would be an interesting subject for Dr. Bennet Omalu because of her history with the WWE and domestic violence. 
  
 Before her death, she posted a 13-minute video on YouTube in a haunting final message. 
  
 She told her fans: "I hope you have a beautiful day. Wake up, wake up, wake up. Or sleep in. Or stay in bed all damn day today. It's Sunday, right? Love you all, peace." |||||

With toxicology reports still months away, Chyna's manager says he knows what killed the former professional wrestler, the New York Daily News reports. Anthony Anzaldo, who found Chyna's body in her California home last Wednesday, says she was killed by an unintentional overdose of legally prescribed Ambien and Valium. “She was inappropriately taking her legally prescribed medication over the course of two to three weeks,” Anzaldo says. “On Sunday night, her body had enough.” According to the Los Angeles Times, Anzaldo denies the death of the 46-year-old wrestler—real name Joanie Laurer—was a suicide attempt. “You are not going to find 60 pills in her stomach,” he says.
