Wrestling legend Jimmy "Superfly" Snuka was ruled mentally incompetent by a Pennsylvania judge -- and therefore will NOT stand trial for the 1983 murder of his ex girlfriend.
Just last year, the 73-year-old was charged with the murder of Nancy Argentino -- who died following an alleged altercation with Snuka in her hotel room before a wrestling match in 1983.
Snuka's legal team argued that he suffers from early onset dementia. His wife took the stand and claimed his mind is essentially gone -- saying he can't pick his car out of a parking lot and will randomly fry chicken at 2 AM.
