After the gunfire died down, agents moved a police vehicle to the scene in an attempt to evacuate Pfeifer before he bled to death. But once the vehicle approached, Drega began firing again, forcing the officers to take cover. Eventually, NH state trooper Charles West and Border Patrol agent Stephen Brooks advanced up a slope to Drega's position. As Drega stepped out from behind a tree to fire, Brooks opened up with his M14 rifle while West fired a slug from his Remington 870 shotgun, killing Drega and ending the gunfight.
