BRUNSWICK, Ga. (AP) _ A Navy corpsman missing since a Marine helicopter crashed in the Atlantic Ocean was found dead Sunday by a team of Navy divers, military officials said.

Petty Officer 1st Class Kevin J. Frank, 39, of Ocean City, Md., had been missing since Saturday morning, when the Marine helicopter went down about 30 miles southeast of Savannah. Frank was stationed at the Beaufort (S.C.) Naval Hospital.

Six Navy divers went down into the 90-feet-deep water and found Frank's body just outside the helicopter Sunday afternoon.

The Marine helicopter had crashed while searching for people on a civilian helicopter that crashed in the same area Friday night.

The civilian helicopter had been carrying two workers on a Marine Corps project: Tim Potts of FK Logistics in St. Augustine, Fla., and Keith Laney, who worked for Northup Grumman in Beaufort, S.C.

Both Potts and Laney died. They were doing maintenance for the Marine Corps on ocean microwave towers that are part of a flight recording system used for tactical aircrew, authorities said.

A Coast Guard cutter rescued four of the five crew members from the Marine helicopter crash. Three were uninjured, and one was hospitalized.

Gunnery Sgt. Terrence Peck said the Marine Corps was investigating both crashes.
