Authorities are searching for an inmate who walked away from the Acton Conservation Camp in Los Angeles County on Wednesday.

Authorities determined that Julian OchoaRuiz, 38, was missing at 11 p.m. Authorities with the California Department of Corrections and Rehabilitation immediately searched the campgrounds and buildings but could not find him, officials said in a news release.
