One of the students taken hostage by a fellow classmate at a Wisconsin high school says the gunman appeared depressed but didn't seem like he wanted to hurt anyone.

Zach Campbell spoke to reporters on Monday after he and 22 other students and their teacher were released unharmed after being held hostage for about five hours at Marinette High School. Police say the 15-year-old gunman shot himself after police entered the classroom Monday night. His condition is unknown.

Campbell says the students were watching a film in class, when the teen pulled out a gun and shot at the projector. He says the gunman then fired another shot.

Campbell says he and the other students tried to keep the gunman calm by talking to him about hunting and fishing.
