The Latest on a shooting at a northern Illinois high school (all times local):
Illinois State Police has identified the man who authorities say fired shots outside a high school auditorium as seniors met for a graduation rehearsal.
Matthew A. Milby was charged late Wednesday with aggravated discharge of a firearm, aggravated discharge at a school employee and aggravated discharge at a school building. He is being held in lieu of $2 million bond.
Police say the 19-year-old fired shots at Dixon High School. A school resource officer confronted the shooter, who ran from the school and shot at the officer. The officer returned fire, striking the suspect.
Authorities say the shooter suffered non-life-threatening injuries and remains hospitalized. The officer was uninjured.
Authorities originally said the man was not a student. However, Superintendent Margo Empen told Sauk Valley Media the suspect was not expelled, did not drop out and was eligible to graduate with his class.
Empen said she could not provide further details because of school privacy laws.
Authorities say students did exactly as they were trained to do when a school resource officer and a former student exchanged gunfire at a northern Illinois high school.

Police have not said why the former student came to the school armed with a gun on a day when students were rehearsing for their upcoming graduation ceremony.
Lockdown has been lifted at the other schools in the city about 80 miles (130 kilometers) west of Chicago.
