A U.S. Marine was taken into custody late last month after a missing 14-year-old girl was found in the barracks of Marine Corps Base Camp Pendleton in Oceanside, California. 

The teen’s grandmother had reported her granddaughter missing on Tuesday, June 13. She’d run away from home several days prior, her grandmother said. 

Deputies responded to the grandmother’s home that same day to take a missing person report and enter the teen’s information into multiple missing persons databases.

Military police at Camp Pendleton located the teen and informed the sheriff’s department. Detectives interviewed the teen and returned her to her grandmother.
