On March 21, 2005, a double homicide followed by a spree shooting occurred at two locations in the Red Lake Indian Reservation in Red Lake, Minnesota, United States. That afternoon, 16-year-old Jeff Weise killed his grandfather (an Ojibwe Red Lake police sergeant) and his grandfather's girlfriend at home. After taking his grandfather's police weapons and bulletproof vest, Weise drove his grandfather's police car to Red Lake Senior High School, where he was enrolled. Weise shot and killed seven people at the school and wounded nine others. The dead included an unarmed security guard at the entrance of the school, a teacher, and five students. After the police arrived, Weise exchanged gunfire with them. After being wounded, he committed suicide inside of a classroom. It remains the deadliest mass shooting by a lone gunman in Minnesota.
