The New York Daily News reported that the shooting took place at AT&T stadium in Arlington about an hour after the New England Patriots beat the Dallas Cowboys 30-6.
Witnesses reported that the two men got into an argument, which escalated to a fistfight. Then, as the gunman held his weapon to the head of the victim, the crowd urged him to shoot, which he did.
Paramedics and police were called to the scene and the unnamed victim, a male in his early 40s, was taken to a local hospital with life-threatening injuries.
The shooter was apprehended by police after he tripped over a low retaining wall and injured his leg while trying to flee the scene.
“I didn’t think he was going to pull the trigger,” said witness Leslie Williams to the Ft. Worth Star-Telegram.
Lt. Chris Cook of the Arlington Police told the Star-Telegram that the two men were tailgaters who had been at the stadium since the afternoon. Their relationship to each other is unknown. The investigation into the shooting, Cook said, is ongoing.
