Brownsville, TN – An Army veteran is being called a hero when he stopped a shooter at a high school football game Friday by disarming him and restraining him until the police arrived.

Patrick Shields was at a homecoming football game on Friday night to watch his son, Taylor, play in the game.

After the game, Shields and his brother were cleaning up their tailgating area, according to USA Today.

“My brother and I were cleaning up, and we heard a bunch of kids hollering and yelling across the street at Walgreen’s, but we didn’t know what was going on,” Shields said, according to USA Today. “Then we heard sounds like fireworks … like pow, pow, pow. And I looked over there and saw the flame coming out of a pistol, and a bunch of the kids were running toward us.”

Shields saw the shooter had the gun in his hand. He said it looked like the gunman was aiming for one person but Shields couldn’t tell who was the target.

Shields, who served in the Army for 22 years and currently is in the National Guard, immediately took action.

“I grabbed him by the arm that was holding the gun and pulled him toward me and threw him up against the fence,” Shields said, according to USA Today. “Then I grabbed him by the back of the shirt and got him on the ground.”

Brownsville Police Assistant Chief Kelvin Evans was headed in that direction and arrived to put handcuffs on the suspect.

“Mr. Shields quick thinking saved many lives,” said Chief Barry Diebold of the Brownsville Police Department, according to USA Today.

Demetrius Harper and Cameshia Murphy were both shot during the incident, according to the police report. Harper was hit twice in the back and Murphy was shot in the foot.

They have since been released from the hospital.

The shooter was only identified as a 16-years old male.

He is charged with criminal attempt to commit first-degree murder, aggravated assault and reckless endangerment. He is being held in a juvenile detention center, according to USA Today.
