(KGTV) — An inmate convicted of sexually assaulting a minor in San Diego was killed during an attack inside a California corrections facility this week.
Officials said on Thursday, 41-year-old Jonathan Watson attacked two inmates with a weapon at California Substance Abuse Treatment Facility, and State Prison in Corcoran. Both inmates suffered head wounds and were taken to a local medical center.
One inmate, 48-year-old David Bobb, died from his injuries while being taken to the hospital. Bobb was sentenced in San Diego on Oct. 17, 2015 to life in prison with the possibility of parole for aggravated sexual assault of a child under 14 years old.
The other injured inmate is in critical condition at a local hospital.
Officials say Watson has been serving a life sentence for first-degree murder and intentionally discharging a firearm causing great bodily injury or death.
The prison specializes in substance abuse treatment and houses more than 5,400 inmates.
