Richard Arena III, an 18-year-old Marine stationed at Camp Pendleton, California, was last seen on January 15, 2017. He failed to report for duty that day and was listed as a deserter by the United States Marine Corps, but subsequent inquiries raised concern that his disappearance may not have been voluntary.

Arena is Hispanic, 5 feet 1 inch tall, about 120 pounds, with black hair. Though officially classified as a deserter, investigators in law enforcement and the military have continued to examine the possibility of foul play or coercion. Details released publicly are limited and the case remains unsolved.
