A U.S. Marine went missing Monday evening when he left Arizona for Camp Pendleton in Southern California.

Lance Cpl. Job Wallace, 20, was last seen at a friend’s house in Surprise, Ariz., which is northwest of Phoenix.

A Border Patrol camera caught Wallace’s truck traveling eastbound on Interstate 10 southeast of El Paso but his mother said law enforcement told her his phone last pinged in Arizona Monday night.

“He got into several colleges and missed scholarship opportunities just so that he could be a Marine because he felt it was his duty to serve his country,” his mother, who lives in Arizona, said.

He was driving a 2004 silver Ford Explorer Sport Trac pickup with the Arizona license plate CRF9682.

The matter has been turned over to the Naval Criminal Investigative Service.
