Pro Wrestler Mike 'Mad Dog' Bell dies at 37

Bell was found Sunday at a Costa Mesa live-in rehabilitation facility, although the cause of death is still to be determined. The coroner is waiting for the results of toxicology tests.

Mike Bell was the subject of a recent documentary his brother Chris directed called "Bigger, Stronger, Faster," which partly dealt with Mike's addition to prescription painkillers and alcohol abuse.

"You can't really blame wrestling, but it's kind of the lifestyle," Chris Bell said. "You have a couple of painkillers to get to the next match, have a couple drinks night to night and it gets out of hand."
