Joseph Hyungmin "Joe" Son (Korean: 손형민; born November 22, 1970) is a South Korean born, American convicted felon and a former mixed martial artist and actor. He is currently serving life in prison in California for torture.
Son was born in South Korea. He moved to California at an early age.
Son was a mixed martial arts fighter and retired with a record of 0–4. Though he had appeared before in Ultimate Fighting Championship's UFC 3 as Kimo Leopoldo's cornerman, Son had his proper debut at the UFC 4 event, entering the tournament billed as a taekwondo black belt and founder of a style called "Jo Son Do". He was pitted against kenpo fighter Keith Hackney, whom Son outweighted by 30 pounds. Son was able to perform a takedown and a guillotine choke attempt, but Hackney countered by punching Son's groin repeatedly, which was legal under the rules of the event. Keith then performed a blood choke with his fingers and Son tapped out, being eliminated from the tournament.
