According to CBS affiliate WFRV, the suspect, 15-year-old Samuel Hengel, was pronounced dead at 10:44 a.m. He was a  student at Marinette High School.

The chief says the boy gave no reason for holding the 23 students and teacher in a classroom at the school for about five hours. None of the hostages were hurt.

Police say the boy shot himself as they burst into the classroom Monday night.

Skorik says the teen had two handguns and fired several shots inside the classroom during the standoff. He says additional ammunition was found in a duffel bag at the school.
