The Navy has called off a search for a L.t.j.g. Asante McCalla, 24, of Lilburn, Ga., according to the Times of San Diego.

At approximately 7 a.m. local time on Aug. 19, McCalla, who was assigned to USS Lake Erie, failed to report for duty. The ship conducted man overboard procedures while operating in the eastern Pacific Ocean with the John C. Stennis Carrier Group Strike Group (JCS CSG), according to the Third Fleet Naval Public Affairs Office.

The Sailor was not found on board and the Navy looked for him for four days, the Times of San Diego reported.

McCalla is a 2012 graduate of Parkview High School in Lilburn. He attended Morehouse State College on a full military officer scholarship, including roles in leadership while a cadet in ROTC, according to his parents. He was recently promoted to his current rank and was close to completing his Surface Warfare Officer designation.
