Authorities say two inmates, one of them convicted of DUI manslaughter, have escaped from North Kern State Prison.

Lt. Barry Bolton of the California Department of Corrections and Rehabilitation says guards at the Kern County facility noticed the two men missing at the 9:30 p.m. count Monday. Bolton says both men were in minimum security and the escape is being considered a walk-away.

The missing men are twenty-six-year-old Filipe Ramirez Suarez and twenty-four-year-old Francisco Sanchez, who also goes by Frankie Escobar. Both men are from Los Angeles County.

Bolton says Suarez was incarcerated for DUI manslaughter with gross negligence; Sanchez was serving time for DUI.

The prison has an escape detail working with local law enforcement to find the men.

Delano is in the Central Valley, about 30 miles north of Bakersfield.
