Authorities are searching for a homicide suspect who was mistakenly released from jail in Contra Costa County last week.

Isaiah Jamon Andrews, 20, was released from the Martinez Detention Facility on Wednesday despite being held on an out-of-state arrest warrant for homicide, the Contra Costa County Sheriff’s Office said Monday. 

Authorities are investigating the circumstances surrounding Andrews’ release, the sheriff’s office said in a news release.

“After Sheriff’s Office staff realized Andrews had been released, we launched a search of the immediate area and confirmed that Andrews was no longer in the area,” the sheriff’s office said.

The search for Andrews – a resident of Kent, Wash. – is being carried out by the U.S. Marshals Service, and local law enforcement agencies have been notified. 

Andrews was also being held at the jail on local charges and a juvenile warrant out of Sacramento, the sheriff’s office said.

Anyone with any information on Andrews’ whereabouts is asked to call 911. The Contra Costa County Sheriff’s Office can be reached at 925-646-2441. For any tips, email tips@so.cccounty.us or call 866-846-3592 to leave an anonymous voice message.
