A 19-year-old is still missing after entering the water on a boogie board Monday in Ocean City. The teen and a friend went into the surf near 10th Street Beach just before 5 p.m. "Initial reports stated that two people were in the water on boogie boards approximately 200 yards from shore. One person was successfully rescued by Ocean City Beach Rescue, while the second person remains missing," the U.S. Coast Guard said. The rescued individual told first responders that the other swimmer lost his boogie board before being hit by a wave and failing to resurface. Members of the Ocean City police and fire departments immediately responded to the beach and began an "intensive search." Local rescue workers, state police and Coast Guard crews used drones, boats, divers and helicopters in an effort to locate the missing man. "At this time the swimmer has not been located and the search remains active," Ocean City police said.
