Chris Mintz, a 30-year-old Army veteran, was in his fourth day of a new semester at Umpqua Community College when shots rang out on Thursday morning.
In the minutes that followed, a lone gunman fired shots into the classroom. Nine people were killed in the attack in Roseburg, Oregon, and the gunman died in a gunfire exchange with police.
But details have emerged that Mintz risked his own life to stop the killer. After hearing shots, family members and witnesses say Mintz rushed to the front of the room and blocked the door to keep the gunman from entering. He was shot several times and had to undergo emergency surgery.
