DIXON, Ill. (WICS/WRSP) -- Latest update:
19-year-old Matt Milby, of Dixon, was released from the hospital at 10:20 a.m. Thursday before he was transported to Lee County Jail.
Milby is charged with aggravated discharge of a weapon in a school building, aggravated discharge of a firearm at a school employee and aggravated discharge of a weapon toward a peace officer.
His bond is set at $2 million and he is waiting arraignment, set for Friday, May 18.
Illinois State Police are continuing their investigation, but have learned Milby's mother purchased the weapon used in the shooting - a 9mm semi-automatic rifle, in 2012.
The investigation is open and ongoing.
The name of the Dixon High School shooter has been released.
19-year-old Matthew Milby, the shooter, is currently in the hospital following Wednesday's shooting event that occurred during graduation practice near the school's auditorium.
A school resource officer shot Milby after shots were fired outside of the school. Milby also shot several times at the officer, but missed.
Milby's mother said her son was going through a hard time prior to the shooting, but never anticipated this outcome.
"It's not that I wouldn't love to pour my heart out. But, the kid's been sad for a long time. A lot of kids steal from him, a lot of kids that have known him all his life, his kindness got taken for weakness and he got thrown under the bus. I just want to leave it at that," Julie Milby said.
School Resource Officer Mark Dallas, who shot Milby, is now on administrative leave.
Classes at Dixon High School were cancelled for Thursday.
