(NBC)- Newly released video shows the dramatic moments a bystander confronted a gunman who opened fire outside an In-N-Out Burger in Twin Falls, Idaho. Video shows the suspect, armed with what authorities described as an AR-style rifle, firing multiple rounds in the drive-thru as customers scrambled for safety. Witness Lane Koehn said the armed bystander likely prevented even more people from being shot. Police credited both the armed civilian and an off-duty Idaho State Police trooper, who also returned fire, with helping save lives during the attack.
