CDCR: Man, 21, sentenced for pimping in O.C. beaten to death at substance abuse treatment facility 

The California Department of Corrections and Rehabilitation is investigating the death of an incarcerated man who was sentenced for pimping in Orange County as a homicide. 

According to a CDCR release, officers patrolling the California Substance Abuse Treatment Facility, Corcoran's facility yard discovered an unresponsive man just before 1:30 p.m. Sunday and immediately called for medical assistance. 

The man – identified as Shawn G. Jackson Jr. – was transported to an outside medical center, where he was pronounced dead at 2:49 p.m., CDCR said. 

Jackson, 21, was received from Orange County on Sept. 20, 2023, to serve four years for pimping. 

An investigation determined that another incarcerated man “battered Jackson Jr., rendering him unconscious,” corrections department officials said. 

The assailant was identified as 31-year-old Jarvis Richerson, who, according to CDCR, has been in and out of prison several times on multiple charges; he is currently serving eight years for rape with force/violence, inflicting corporal injury and assault with a firearm.
