A teenager died in a single-vehicle crash Sunday night in Lamar County.

Sgt. Jeremy J. Burkett of the Highway Patrol Division said the incident happened at about 7:50 p.m. Sunday on Dempsey Road, about five miles west of Sulligent.

A Polaris Ranger ATV operated by a 15-year-old overturned.

The teen, who was not using a seat belt at the time of the crash, was ejected, Burkett said. A 15-year-old passenger, from Sulligent, was injured and transported to a local area hospital.

Troopers with the Alabama Law Enforcement Agency continue to investigate.
