DALLAS, Ga. -- A Dallas police officer shot a man holding a rifle on the Silver Comet in Dallas, Ga. on Wednesday.

According to Dallas, Ga. Police, the incident happened around 2:12 p.m. near the Rambo Nursery. A 911 caller reported a man on the trial with a gun who was shooting.

A Dallas Police officer responded and asked Paulding County Sheriff's deputies for backup. When law enforcement arrived, they found the man sitting at a picnic table. The officers told him to drop the gun but he refused. He allegedly then stood up and waved the rifle and continued to ignore commands.

“He began moving the rifle back and forth from left to right, and when he started to point it at one of the officers, the Dallas Police officer fired on him,” said Capt. Gorman, a detective with the Dallas Police Department. They fired two or three shots at him.

The suspect was taken to Wellstar Kenneston Regional Medical Center and headed into surgery, 11Alive's Duffie Dixon reports.

The GBI has now taken over the investigation, as they do in every case where a law enforcement officer fires a weapon.

Rebecca Vaughn, who works at Rambo Nursery, said she had a heart-stopping moment when she faced the suspect on the trail.

She was coming back from a meeting and was parking her car when she noticed the man on the trail with a gun.

“I could see him through the woods," Vaughn told 11Alive. "He was very slowly walking down the trail and had a long gun like a rifle in his hand.”

She said they made eye contact with one another and he spoke to her.

“He asked me if I could give him a ride," she recalled. "I ignored him, ran inside to my supervisor and said there’s a man outside with a gun."

Moments later someone called 911 saying they heard shots fired.

Now, investigators are trying to figure out what exactly what the man was doing on the trail with the gun, on a section that is usually packed with people walking and riding bikes.
