The office will now conduct tissue and toxicology studies to try to determine what killed the 44-year-old Adams, who wasn't breathing when his wife found him unconscious in their Tampa home Monday morning. A completed autopsy report is expected in six to eight weeks.

Adams' body showed no visible signs of injury and foul play was not suspected, police said.

Adams, a former world tag team champion, last performed for the World Wrestling Federation in 2001 and served intermittently on the roster beginning in 1990, World Wrestling Entertainment said.

After leaving the WWE in late 2001, Adams competed in Japan and then attempted a career in boxing, the WWE Web site said. He wrestled his last match in January 2003 when a spinal injury forced him into retirement.

Adams' death comes less than two months after pro wrestler Chris Benoit killed his wife and son before hanging himself on the cable of a weight machine in his Georgia home. Prescription anabolic steroids were found in the family's home, raising questions about whether the drugs played a role in the killings.
