A family dispute in a Roswell apartment ended in a fatal shooting on the morning of Thursday, September 25, 2025. Police responded to Rosemont Apartment Homes on Rosemont Parkway and found 56-year-old Gary Clark shot to death inside a unit. Investigators say Clark and his 29-year-old son, Tristan Dinnall, had been arguing before the shooting.

Witnesses reported seeing the shooting and gave officers a description of Dinnall and the vehicle he drove. A responding officer located the car minutes after the 911 call, conducted a traffic stop and arrested Dinnall without incident. He was charged with murder and possession of a firearm during the commission of a felony and was booked into the Fulton County Jail held without bond. Authorities have described the incident as an isolated domestic-related act and are not seeking other suspects.
