Janesville firefighters and police officers continue to patrol the streets despite the record-setting low temperatures. Glen Hageman, who has spent close to two decades of winters as a police officer, says working through the cold is part of the job. "We still have crimes being committed," he said. "Criminals still think like criminals." Hageman says during the polar vortex, crime patterns can look different. "You don't have your normal accidents, thefts and things like that," he said. Rather, he says the majority of the calls the department gets when the weather gets cold are wellness checks, or people calling about the safety of others. "Someone will call and say, 'Hey, we need to go check on that person because they shouldn’t be out walking in the weather like this,'" he said.
