Quinton Thornton, 35, was shot and killed on October 6, 2017, at a Marathon gas station on John A. Merritt Boulevard in Nashville. The shooting followed a verbal altercation between Thornton and the occupants of a Lincoln Continental; Thornton walked over to the parked Lincoln and was shot in the back. He was taken to Vanderbilt University Medical Center and died of his injuries.

Investigators identified two suspects connected to the incident. Witnesses said the gunman got into the passenger side of the Lincoln after the shooting and the vehicle fled. A 20-year-old alleged getaway driver, Terry Martin, was arrested in Dyersburg on October 9, 2017. A 57-year-old man, Danny Haskins, was arrested in Dyersburg on October 22, 2017.

Are there witnesses or surveillance footage from the Marathon station or nearby businesses that could clarify the timeline or sequence of events?
