Jailed UFC veteran 'Joe Son' suspected of killing prison inmate

Rape, torture, homicide ... is there anything this guy can't do?
Former UFC punching bag Joseph Hyungmin Son, who is serving a life sentence after being convicted of torture in a brutal gang rape case, is now under suspicion for killing his cellmate at California's Wasco State Prison on Oct. 10, 2011.
The story first surfaced earlier today on The Underground with a chilling account from "SoCal PriznGard:"

Ex UFC fighter, Joe Son has murdered his cellmate. While serving a life sentence for gang rape, Joe Son has been attacked several times by other inmates who do not tolerate rapists in prison. It has not yet been determined why he killed his cellmate or how ... Joe and dead guy only ones in cell together. Guard doing count, sees celly is unresponsive, medical arrives. CPR performed. Celly has trauma to chest area. Pronounced dead. Innocent until proven guilty but looks like he did it. These are the only facts that I have right now. Investigation still in progress since it just happened on Monday around 5:00 pm.

Now the Wasco Litigation Department has sent out a press release (via Cage Potato) confirming the inital report:

Officials from Wasco State Prison-Reception Center (WSP-RC) and the Kern County District Attorney's Office are investigating the death of an inmate as a homicide. The inmate, whose name is being withheld pending notification of his next of kin, was found dead in his cell about 5:50 p.m. October 10, 2011.
The 50-year-old inmate was received at WSP-RC from San Luis Obispo County on June 23, 2011, as a parole violator with a new term for failure to register as a sex offender. He received a 2-year sentence.
Joseph Son, 40, has been identified as a suspect in the case. Son was received at WSP-RC from Orange County on September 16, 2011, on a life sentence with the possibility of parole for torture.

"Joe Son" (0-4), also known to non-MMA fans as "Random Task" from Austin Powers: International Man of Mystery, is probably best known in the fight community for having his balls demolished by Keith Hackney back at UFC 4 en route to a first round submission loss.
