The U.S. Marshal's Service, the Jacksonville Police Department and the Onslow County Sheriff's Office are expanding their search for a missing Camp Lejeune Marine. Staff Sergeant Robert Loughridge was last seen on August 3. He's been a Marine for 11 years and was assigned to the family readiness post on the Jacksonville base. Officials say Loughridge has not contacted any of his family members since he disappeared. The search area has now been increased to include hundreds of acres.
