CHINO, Calif. (AP) — Authorities are looking for an inmate firefighter who walked away while assigned to a crew working on the remnants of a Southern California wildfire.

State corrections officials say 31-year-old Armando Castillo walked was last seen about 4:45 p.m. Sunday, when he was among inmate crews working the so-called Canyon Fire 2 in Orange County.

Castillo was sentenced in Los Angeles County last year to a five-year term for possession of a firearm and evading a peace officer while driving recklessly. He was scheduled to be released on probation in May 2018.

He had been assigned to Oak Glen Conservation Camp in Yucaipa.
