A newlywed Marine couple have surrendered to authorities, two weeks after their disappearance alarmed relatives who said they initially suspected foul play.

Marine officials say Lance Cpl. Margaret McMahon-Reid and Pfc. George Reid II turned themselves in after being placed on "unauthorized absence" status for failing to report for duty. Officials say the couple were scheduled to be returned to Camp Pendleton Monday.

The couple disappeared from their Escondido apartment on March 31. Relatives initially told police they suspected foul play. But police dropped the case five days later, saying it appeared the couple simply packed up and left.
