Gunfire rang out at the Forysth County Courthouse in Cummings, Ga., Friday after a man opened fire on a deputy, injuring him in the leg. The gunman was shot and killed a short time later.
Forsyth County Sheriff Duane Piper told WSB TV the shooter, Dennis Marx, walked into Forsyth County Administration Building on East Main Street at about 10:30 a.m. and opened fire. He was armed with an assault rifle and IEDs, according to authorities. Prior to walking inside, Piper said Marx threw stop sticks on the road so that cars could not approach.
Marx was approached by a deputy who he then shot in the leg, Piper confirmed. Piper said the deputy was taken to North Fulton Hospital in Roswell with non-life threatening injuries.
The SWAT team, which was on its way to a separate incident, arrived at the courthouse within 37 seconds. Marx was shot dead in front of the court house a short time later.
Piper described Marx’s home as a “bomb” and said \he was confident it was setup as an explosive trap.
