Pro wrestling legend Killer Karl Kox (real name: Herb Gerwig) passed away on Thursday morning at the age of 80.
Gerwig was a legitimate wrestling headliner in the 1960s and 1970s and was one of the all-time top villians in Australia, in addition to his multiple main-events in the United States.
Gerwig suffered what was described as a massive heart attack back in late October, and according to reports, never fully recovered.
