Marine Corps Identifies 4 Service Members Who Died In Chattanooga Attack

Updated at 10:40 p.m. ET

Their experience levels ranged from multiple deployments in war zones to one year in the service with no deployments. Their homes ranged from Georgia to Wisconsin, but their lives converged in Thursday's deadly attack in Tennessee.

The Marine Corps has formally identified the victims as Gunnery Sgt. Thomas J. Sullivan, Staff Sgt. David A. Wyatt, Sgt. Carson A. Holmquist, and Lance Cpl. Squire K. Wells.

All died in Thursday's attack after a gunman opened fire at a joint Navy and Marine Corps facility in Chattanooga, in an incident that followed an attack on a recruiting center. A Marine, a sailor and a police officer were wounded.

The dead include Lance Cpl. Skip Wells, 21, who had just started a two-week assignment in Chattanooga.

As NPR's All Things Considered reports, a family friend said today, "Up to the minute this incident happened, he was a very proud serving Marine."

"Please keep our fallen Marines in Tennessee and their families in your thoughts and prayers," Commandant of the Marine Corps Gen. Joseph F. Dunford Jr. said Friday. "Also pray for a speedy recovery of those wounded and affected by this tragedy. Our focus remains on supporting the families of our Marines."
