A student wielding a handgun released 23 classmates and a teacher in a Wisconsin high school after holding them hostage for several hours. A school administrator called police at 3:48 p.m., saying that the young male student had gone into a classroom and taken hostages. About 40 law-enforcement personnel, including hostage negotiators, descended on the school, located in the town of Marinette, which borders Lake Michigan. The student attends Marinette High, and the Marinette police chief said he believes he is a student in the class he’d taken over. No injuries were reported.
