HASTINGS, Minn. - Rene Doffing once delivered life-saving CPR to a 2-month-old baby. Another time, gun in hand, he helped subdue a suicidal man.
While chasing a suspect inside a house, he literally kicked in the door on a large marijuana operation. Police later learned the property was ringed by homemade bombs.
