Jonny Tapia's body was found by a family member on Sunday; authorities reported that nothing seemed suspicious about the death.
While having won world titles in three weight classes, Tapia is said to have also led somewhat of a chaotic life.
Jail sentences, struggles with mental illness, suicide attempts and being declared clinically dead five different times as a result of drug overdoses were some of the hallmarks of Johnny Tapia's lifestyle after the ring.
According to a report done by the New York Times, Tapia who was 5 feet 6 inches, would often be forced to fight by his uncles. If he ever lost a match, they would beat him, Tapia said.
Tapia had the words Mi vida loca, or my crazy life, as a tattoo on his belly and had eventually made that his motto after he thought he had outgrown his first, baby-faced assassin, according to The Times.
Tapia would win his first 22 fights as a professional boxer before eventually being suspended from the sport in 1990 for failing three drug tests.
Three and a half years later, the troubled boxer would return to win five fights before defeating Henry Martinez to win the world super flyweight title in 1994.
Tapia would go undefeated for 18 more bouts before beating Nana Konadu to win the bantamweight title (118 pounds) and become a two-division world champion.
His first to defeat came to the hands of Paulie Avala in June 1999 in what The Ring magazine called the fight of the year.
Mike Tyson has been quoted as calling Tapia one of the greatest fighters ever, with a record of 59 wins, 30 by knockout; five losses; and two draws. He was knocked out only once.
