Stevie Lee Richardson, the actor in projects such as Jackass, American Horror Story, and former TNA wrestler, died at 54.
His family confirmed the sad news and said he died "unexpectedly" in his home.
Aside from being an actor, Lee was also popular with wrestling fans, going by the stage name of 'Puppet, The Psycho Dwarf.'
