Bartlett, 23, died after he was struck by a car while trying to secure a mattress and box spring to the top of a vehicle along McGinnis Ferry Road about 9:30 p.m. on June 2.
Witnesses told officers the vehicle that struck Bartlett was a dark-colored four-door sedan, possibly a black BMW. Investigators believe the vehicle suffered damage to the right bumper and hood, windshield and passenger-side door.
Bartlett was the brother of Pittsburgh Steelers defensive end Stephon Tuitt, who attended Notre Dame and played high school football at Monroe Area High in Walton County. Tuitt, who was selected in the second round of the 2014 NFL draft, has played seven seasons with the Steelers.
Bartlett’s mother, Tamara Bartlett, is a deputy with the Gwinnett County Sheriff’s Office, the agency confirmed.
The hit-and-run remains under investigation. Anyone with information about the case or the driver involved is asked to call Johns Creek police at 470-774-3358 or email Investigator Alexander Hennessee at firstname.lastname@example.org.
