A murder suspect's parents took him to a police station Saturday to turn himself in after he was accused of fatally shooting a man in the parking lot of an east Oak Cliff grocery store late Friday.

Marque Townsend, 20, was arrested on a murder charge and booked into the Dallas County jail on $100,000 bail.

According to the arrest warrant, Townsend got into an argument with Jimmy Davis, 23, around 11:40 p.m. outside the Gold Star Food Store, 2837 E. Ledbetter Drive.

Police say Townsend pulled out a pistol with an extended magazine and shot Davis several times in the chest, then continued shooting Davis in the back as the mortally wounded man tried to escape.

Davis was taken to Baylor University Medical Center, where he later died.

Surveillance cameras at the grocery store captured the shooting on video, showing Townsend with a distinctive bandage around his left elbow.

Townsend arrived at the Dallas Police Department Central Patrol Division with his parents around 6:30 p.m. Saturday. His parents told police he was involved in the shooting at the Gold Star Food Store and was turning himself in.

According to the warrant, Townsend still had the bandage around his left elbow when he turned himself in, leading police to believe he was "clearly" their suspect.
