NORFOLK -- A memorial service honoring Master-at-Arms 2nd Class Mark A. Mayo was held at 10 a.m. Monday at Naval Station Norfolk.
Mayo, 24, was killed during a shooting aboard USS Mahan on March 24. Mayo was assigned to Naval Security Forces on the base.
The Hagerstown, Md. native enlisted in the Navy in Oct. 2007 and reported to Naval Station Norfolk in May 2011.
The shooting remains under investigation.
The memorial service is not open to the public, the Navy said.
In his hometown Thursday night, about 70 people attended a City Park candlelight memorial service. They filled metal benches to offer support and condolences to Mayo's parents and three siblings, seated in the park's bandshell. Two poster-sized photos of Mayo in uniform flanked the speaker's podium near a bunch of blue-and-white balloons - the colors of Williamsport High School, where Mayo was a wrestling star, and the Dallas Cowboys, represented by a team blanket draped over an empty chair. Photos, video of the service from Herald-Mail Media.
His boyhood pastor, the Rev. Paul Berry, told the crowd that Mayo deliberately laid down his life to save another sailor by jumping between her and a civilian gunman who was trying to board a ship.
The gunman, truck driver Jeffrey Savage, was then killed by Navy security forces responding to the scene.
Mayo's brother Terrail Blair says he's proud of his 24-year-old baby brother. Blair says he feels connected to the families of the U.S. Army soldiers killed Wednesday in a shooting at Fort Hood, Texas.
A funeral is scheduled April 11 in Washington, D.C., where the family lived before moving to Hagerstown in 1998.
