LITTLE ROCK Ark. (AP) A 19-year-old Arkansas man has been sentenced to 60 years in prison after pleading guilty in the killing of an airman from Maine who tried to stop him from robbing a gas station.

Drequan Lamont Robinson of North Little Rock pleaded guilty Monday to first-degree murder and aggravated robbery in the March 2019 shooting death of Senior Airman Shawn Arnold McKeough Jr., a Westbrook native.

The Arkansas Democrat-Gazette reports that Robinson must serve at least 70 percent of his sentence before he’d be eligible for parole.

Security footage from the convenience store showed McKeough lunge at Robinson’s accomplice before Robinson turned and shot McKeough in the face.

Robinson’s three accomplices also pleaded guilty and were sentenced to shorter prison terms.
