Navy official identifies civilian who shot sailor at base; records show he is convicted felon

The Virginia truck driver who killed a sailor aboard a Naval destroyer served prison time for manslaughter and drugs, but it's still unclear what led him onto the base earlier this week.

The Navy identified the shooter Thursday as 35-year-old Jeffrey Tyrone Savage of Chesapeake, Va., but officials were still searching for clues about the shooting.

Savage was killed by Navy security forces Monday night aboard the USS Mahan after he took a gun from a petty officer who was on watch for the ship and used it to shoot Petty Officer 2nd Class Mark Mayo, who was providing security at Naval Station Norfolk.

Navy officials have said there's no indication the attack was planned or had any link to terrorism.
