CAZENOVIA, Wis. – A teenager who pried open his family’s gun cabinet brought two weapons to his rural school Friday and shot the principal to death after a struggle with adults and other students, authorities said. The 15-year-old was taken into custody and charged as an adult with murder, the district attorney said. No one else was hurt. Authorities said the teen had complained about being teased by other students and decided to confront teachers and the principal using a shotgun and handgun taken from his parents’ bedroom. The shooting also came one day after the principal gave him a disciplinary warning for having tobacco, according to a criminal complaint.
