Police responded to reports of the explosion shortly before 9 a.m. on Monday at Newaygo High School located in the small rural city of Newaygo, Michigan. They found the 16-year-old student who accidentally set off the device with moderate to severe injuries from the blast, according to MLive.
Newaygo Schools Superintendent Peggy Mathis characterized the incident as “not an attack or designed to be something malicious, but a serious lack of judgment.” She added that the blast “was not somebody planting an explosive device in order to hurt our students. Those directly involved with the situation determined that was not the intent.”
All schools in the county of just over 48,000 people went into lockdown, and Newaygo High School was evacuated in the immediate aftermath of the explosion, state police said. There is an investigation underway that includes assistance from the FBI and the Bureau of Alcohol, Tobacco, Firearms, and Explosives.
State police said troopers executed a search warrant at a residence where they believe the explosive was made. Students at the high school where the explosion occurred were dismissed for the rest of the day because of the investigation and presence of lingering smoke.
