BUFORD — One man is dead and another wounded in a Tuesday morning incident near the Hall-Gwinnett county line. Gwinnett Police are using a helicopter to search for “any additional victims and evidence,” they tweeted before 9 a.m. No arrests have been made and law enforcement continues to investigate the area. Officers were sent to the Duncan Preserve subdivision off Sardis Church Road before 4 a.m. after a call referencing “discharging firearms” in the area of Express Lane. A young man in his early 20s was found with a gunshot wound in front of the neighborhood clubhouse at the bottom of Express Lane. He is now being treated at Gwinnett Medical Center in Lawrenceville, police report. His injuries aren’t believed to be life-threatening. About 7 a.m., a second victim was found dead 200 to 300 yards away in a vehicle. The second person is believed to have been killed by a gunshot, but investigators have yet to move the body to determine the exact cause, said Gwinnett Police spokeswoman Michele Pihera. The car was found in Hall County along a dirt road that follows power lines that run through the neighborhood off Sardis Church Road. Investigators believe there was a shooting in front of the clubhouse, after which one of the victims drove down the utility road, where he died. Investigators are looking into whether more people are involved. The identities of those involved are being withheld until next-of-kin are notified.
