US hostage-taker aged 15 dies of self-inflicted gunshot wound

Authorities say a 15-year-old boy who held 23 students and a teacher hostage in a Wisconsin classroom has died at a Green Bay hospital from a self-inflicted gunshot wound.

Marinette Police Chief Jeff Skorik says sophomore Samuel Hengel died on Tuesday. Skorik says Hengel, of Porterfield, shot himself as police stormed a classroom at Marinette High School Monday night, The Associated Press reports.

The student, Samuel O. Hengel, entered his classroom at Marinette High School in northeastern Wisconsin on Monday with two handguns and ammunition.

After hours of waiting - and what turned into a conversation about hunting and fishing, students said - several students were allowed to leave the room. Law enforcement officials were entering the room when the student shot himself, they said.

No one else was injured. The teenager was described as a good student who said little during the standoff about what was troubling him, according to New York Times.
