Peery, a 28-year-old resident of Ladysmith, Wisconsin, was patrolling about 35 miles south of Exeland that morning with fellow warden John Hagen. "About 12:20 Hagen received a cellphone call from Joseph Crotteau, his long-time friend and the brother of Robert [Crotteau, one of the victims]," Peery recalls. "He described the scene and didn't know what to do. We informed other law enforcement agencies and raced to the area to set up a perimeter roadblock. One of the victims had written Vang's back-tag number in the dust of an ATV at the scene, so we ran a check and knew exactly who we were looking for."
