WAUKESHA, WI — A day after a 17-year-old was shot by Waukesha Police at Waukesha South High School, police officials revealed new details about Monday's shooting.

Waukesha Police Captain Dan Baumann in a Tuesday afternoon press conference said the 17-year-old student had become angry at a fellow student, and brought two guns to school — both pellet guns. Authorities said the guns the student brought to school were indistinguishable from conventional firearms. "I can get 100 firearms experts to look at that picture right there, and 100 of them will say that is a firearm," Baumann said. Related Reading

During the press conference, Baumann said a concerned Waukesha South High School student approached a School Resource Officer Monday morning, saying that a student brought a gun to school and pointed it at another student's head. At the time, the School Resource Officer and a Police detective were in the school office. They ran to the classroom where the gun-carrying student was located. Baumann went on to say that the classroom was quickly evacuated as the School Resource Officer and Detective began to negotiate with the gun-carrying student.

Baumann said the student removed a gun from his waistband and pointed it at officers. A Waukesha Police officer shot the student a total of three times: once in the upper right thigh and in the arm twice. Officers immediately rendered aid to the student, who later went through surgery and intensive care at Children's Hospital. He is currently in stable condition as of Tuesday afternoon, police said.

Waukesha School District Superintendent Todd Gray called the incident "clearly a superintendent's worst nightmare. We are grateful for response of the school resource officer, police and sheriff," he said. "We will be reviewing the situation and working with students, staff and the police department to allow our students to resume learning tomorrow."
