IMPERIAL— Centinela State Prison (CEN) officials are investigating the death of an incarcerated person as a homicide.
On Monday, Nov. 14 at 10:16 a.m., staff quickly responded when two incarcerated people, Jose Perez and Juan Serrano, allegedly attacked incarcerated person William Quintero in a recreation yard. Staff contained the incident within minutes. Two inmate-manufactured weapons were recovered. No staff members were injured.
Quintero suffered multiple injuries and was airlifted to an outside hospital. He was pronounced deceased at 7:33 p.m. The Riverside County Coroner will determine Quintero’s official cause of death.
Perez and Serrano have been moved to segregated housing as the investigation continues. Officials have limited population movement on the yard to facilitate the investigation and notified the Office of the Inspector General.
