ENID, OKLA. ? Shirley Lehman was looking forward to her grandson’s return in about three weeks from military duty in Iraq.

But a visit from Air Force personnel over the weekend turned an anticipated joyous reunion into one of sorrow.

Air Force Staff Sgt. Dustin W. Peters, 25, was killed Sunday when his convoy was hit by a homemade bomb about 155 miles north of Baghdad, officials at Little Rock Air Force Base in Arkansas said in a statement.

Peters, of El Dorado, Kan., was assigned to the 314th Logistics Readiness Squadron.

“It’s been such a shock,” said Lehman, who lives in the Enid area along with Peters’ father, Dennis Peters.

Lehman said her grandson called last week to say he’d be bringing his young son to visit the family when the airman came home on leave Aug. 3.

Dustin Peters entered the Air Force in January 1997, completing basic training at Lackland Air Force Base and technical training at Fort Leonard Wood, Mo.

He was assigned to the 332nd Air Expeditionary Wing and attached to the U.S. Army’s 494th Truck Company at Balad Air Base in Iraq.

“We lost a valuable member of the Little Rock Air Force Base team and our Air Force family,” Col. Joseph Reheiser, 314th Airlift Wing commander, said in a statement. “Sgt. Peters will be missed, but his dedication and sacrifice will never be forgotten.”

Dustin Peters was decorated with the Air Force Commendation Medal with one Oak Leaf Cluster and with Valor, and an Air Force Achievement Medal with one Oak Leaf Cluster.

Lehman worried about safety for Dustin Peters, who was serving his second tour of duty in Iraq and had been to Kuwait, Saudi Arabia and Afghanistan during his service in the Air Force.

“There were times when I asked him to get out (of the military),” she said. “He was just so dedicated.”
