The Marine Corps identified the victim of Friday’s deadly barracks shooting aboard the Beaufort, South Carolina, air station as Cpl. Tyler P. Wallingford.

Wallingford was a 21-year-old aircraft ordnance technician assigned to an F-35B training squadron known as Marine Fighter Attack Training Squadron 501, or VMFAT-501.

He was killed following being shot in the barracks around 9:30 p.m Friday.

Another Marine, Cpl. Spencer T. Daily, also an ordnance tech with VMFAT-501, is a suspect in the incident and currently is in custody, according to 2nd Lt. Kevin L. Buss, a Marine spokesman with the Beaufort air station.

“Our deepest condolences go out to the family and friends of our fallen Marine,” Buss told Marine Corps Times in an emailed statement.

Naval Criminal Investigative Service is leading the investigation of the shooting.
