5. The Black Baron (Kevin Cawley)
British native Kevin Cawley worked most of his career under a hood as “The Black Baron.” In October 1992, Cawley was working in a battle royal for All Star Wrestling at the Lewisham Theatre in Catford. During the bout, Cawley fell to the corner, and was taken out while the match continued. A heart attack had claimed the life of another wrestler with the Black Baron dying at age 46.
