(GREEN BAY, Wis.) -- The young gunman who took more than 20 students and a teacher hostage Monday night has died of a self-inflicted gunshot wound.
Shortly after all the hostages were released unharmed, police heard three gunshots, prompting officers to "breech the door," police said. The student then shot himself.
The gunman, identified as Samuel Hengel, a resident of Porterfield, Wisc., was transported to Bay Area Medical Center where he later died.
Authorities responded to the hostage situation Monday at Marinette High School. Police said a 15-year-old male student armed with a handgun was holding 23 students and a teacher hostage in a classroom.
Although a hostage negotiating team was assembled inside the school, direct contact was not made with the student and police were unaware of the suspect's demands or motive.
