Bexar County medical examiner records indicate Ayala died at the gym where he was trying to build a career as a trainer. There was no immediate cause of death.
Ayala, a 1979 Golden Gloves middleweight champion, was 19 when he was arrested and later convicted of raping a schoolteacher in New Jersey. He was undefeated in 22 bouts with 19 knockouts and set to fight Davey Moore for a junior middleweight title before the arrest.
After serving 16 years of a 35-year term for rape, Ayala was involved in several incidents in Texas as he tried to revive his boxing career. He was shot in the left shoulder by a woman after allegedly breaking into her home and refusing to leave in 2000.
