A soldier from Wyoming County has died of wounds suffered in a shooting Wednesday outside a convenience store in Killeen, Texas, an Army spokesman announced Monday.

Spc. Austin James Sampson, 25, who was stationed at Fort Hood in Killeen, died Friday in Scott and White Memorial Hospital, Temple, Texas.

He was the son of Wesley G. and Pamela Scott of Hillside Road, Bliss, and a 2006 graduate of Letchworth Central High School, where he played varsity football.

Witnesses told Killeen police that Sampson and two other soldiers were sitting in a maroon SUV outside the Star Mart convenience store not far from Fort Hood at about 5:30 p.m. when a black man with dreadlocks stepped out of a white Lincoln Town Car, walked up to their vehicle and fired several shots at them.

Sampson’s companions were taken to Carl R. Darnall Army Medical Center in critical condition. The gunman is still at large. A $1,000 reward has been offered for information leading to an arrest.

Sampson enlisted in the Army in July 2006 as a cavalry scout and had been based at Fort Hood since November 2006.

He was deployed to Iraq from November 2007 to January 2009 and to Afghanistan from August 2010 to August 2011. He earned several commendations and service medals.

At the time of his death, he was assigned to Headquarters Troop, 3rd Squadron, 3rd Cavalry Regiment, at Fort Hood.
