NASHVILLE, Tenn. (WKRN) – Metro police have made an arrest in connection to a shooting that left one man dead in the parking lot of a Jack in the Box in South Nashville. 

The shooting happened on Tuesday at 4:30 p.m. at the Jack in the Box on Largo Drive right off of Harding Place. 

According to an affidavit, an altercation occurred in the parking lot of the fast-food restaurant between several employees. Metro police say the incident is believed to have begun after the girlfriends of the two men were involved in a physical altercation. Officials say the girlfriends are also employees at Jack in the Box.

Courts documents say during the altercation, video surveillance captured Trey Scales, 28, grabbing a gun from his vehicle, pointing it at his co-worker and shooting him. Scales initially told officers that he shot his co-worker in self-defense, but police say video evidence showed otherwise.

The co-worker, who has been identified as 30-year-old Keanthony Thompson, was transported to Vanderbilt University Medical Center where he was pronounced dead.
