DIXON, Ill. (AP) — An August trial date has been set for the 19-year-old man who has pleaded not guilty to charges he opened fire before graduation practice at Dixon High School last month.

Matthew Milby Jr. faces felony gun charges and is being held in jail in lieu of $2 million bond. Milby is accused of taking a semi-automatic rifle to Dixon High School on May 16 as graduation practice was taking place in the gym.

Authorities allege Milby, who was a member of the graduating class, fired at a gym teacher and was running away when he was confronted by school resource officer Mark Dallas.

Milby is accused of firing at Dallas. Dallas returned fire, striking him in the shoulder and the hip. Neither Dallas nor the gym teacher was injured.

Milby’s trial is set to begin Aug. 20 before Lee County Circuit Court Judge Charles T. Beckman.
