— The Navy will award its highest non-combat decoration for heroism Friday to a Hagerstown sailor killed last month in a shooting in Norfolk, Va., officials said.

Petty Officer 2nd Class Mark A. Mayo, who was assigned to Naval Security Forces at Naval Station Norfolk, was shielding a sailor from a civilian truck driver who had taken her gun during the March 24 confrontation aboard the destroyer USS Mahan, officials said. Mayo was 24.

Jeffrey Tyrone Savage shot Mayo, officials said. Naval Security Forces then shot Savage to death, officials said.

Capt. Robert E. Clark Jr., the commander of Naval Station Norfolk, said last month that Mayo's actions were "nothing less than heroic."

"He selflessly gave his own life to ensure the safety of the Sailors on board USS Mahan," he said.

Adm. Mark Ferguson, the vice chief of naval operations, is to present the Navy and Marine Corps Medal to Mayo's family during a private ceremony Friday before the sailor is buried at Arlington National Cemetery.

Gov. Martin O'Malley ordered the U.S. and Maryland flags on all public buildings in the state to be flown at half-staff from sunrise to sunset on Friday in honor of Mayo.

Mayo enlisted in the Navy in October 2007, and reported to Naval Station Norfolk in May 2011.
