When a friend found Chyna's body on Wednesday evening, the former wrestling icon had been dead for at least one or two days.

The news came as authorities still sift through her Redondo Beach, California, home, trying to figure out what caused the former professional wrestling pioneer to pass away at the age of 45.

Initial indications are that she could have accidentally overdosed on prescription medication.

According to TMZ, there was no suicide note left in the home. The last known contact she had with anyone was Sunday evening, a full 72 hours before her deceased body was found. Sources told the celebrity website that she had been dead for "a day or two."

Upon a search of the home, authorities found no illegal drugs, but they did find several legal prescription bottles, but "nothing out of the ordinary." The bottles, the website said, were not emptied, which leads many to believe her death was not a planned suicide.

"Several neighbors told investigators they suspected 'overdose' as the cause of death since she'd seemed 'under the influence' lately," TMZ said.

Her struggles with depression and substance abuse were well known.

She was arrested in 2005 after allegedly attacking then-boyfriend Sean "XPac" Waltman in front of his kids. That same year she reportedly got naked and jumped into a nightclub fish tank during a drunken outing. She checked into treatment a short time later.

Two weeks ago, the former WWE pro missed her schedule appearance at Wrestlecon in Dallas, Texas, and posted an apology on her social media pages.

"From the bottom of my heart I want to apologize to all of my fans who came out to wrestlecon to see me," she wrote. "Things did not work out as I had planned and I will make it up to you guys at some point. Just know that I am ok."

Her death shook up the wrestling community. Like many, her longtime wrestling companion Paul Levesque, who wrestles as HHH, took to Twitter upon her death.

Chyna, he wrote, was "someone who wasn't afraid to blaze her own trail & create a path for those who would follow. A pioneer whose star shined bright. #RIPChyna."

The popular in-ring figure of the late 90s also built a career away from the wrestling ring. She posed for Playboy and starred in several pornographic films. She also appeared on several reality shows, namely "The Surreal Life" and "Celebrity Rehab."
