A 23-year-old senior airman stationed at Little Rock Air Force Base in Arkansas was fatally shot Friday while trying to stop an armed robbery.

Shawn Mckeough Jr., who served in Germany, Kuwait, and South Korea, was shot at the Valero Big Red convenience store in North Little Rock on Friday around 11 p.m. when he attempted to stop two people who barged in with handguns, police said. The two armed individuals then left the store without taking any money.
