Mitch Mortvedt, assistant director of Iowa Department of Criminal Investigation, said a sixth-grade student at Perry Middle School, which is connected to Perry High School, was killed in the shooting. Five others, four students and a Perry school administrator, are being treated at local hospitals. One is in critical condition, Mortvedt said, and four others are in stable condition.
According to Mortvedt, responding officers found Butler dead of an apparent self-inflicted gunshot wound. In a subsequent search of the school, officers located a "rudimentary" improvised explosive device. It was disarmed without further incident or injury, he said.
