As the death investigation was getting underway, Riverside Sheriff’s Sgt. Joshua Parker explained that about 4 a.m.,
deputies assigned to the jail located an adult male unresponsive “within his cell in a housing area of the facility.”

 Deputies immediately summoned jail medical personnel, as well as Cal Fire/Riverside County Fire and other emergency personnel, and began life-saving measures.

Despite their efforts, when Cal-Fire arrived they pronounced the man deceased at the scene.

Based on the circumstances Riverside Sheriff’s investigators along with Southwest Station’s Investigations Bureau and Cois Byrd Detention Center Investigators responded and assumed the investigation. 

The victim’s identity has not been released pending notification of the man’s family, and officials have not specified why the person was incarcerated or how long he had been at the facility.

“Due to the ongoing investigation, no further information will be released at this time,” said Parker. 

Anyone with information regarding this incident is encouraged to call Investigator Franchville of the Southwest Sheriff’s Station at (951) 696-3000. Callers can refer to incident file number SC183490005 and can remain anonymous.
