UPDATE: DIXON, Ill. (WIFR) - A former Dixon High School student accused of firing a rifle during graduation rehearsal is back in court as prosecutors move one step closer to a trial date.
Matt Milby faces three counts of aggravated discharge of a firearm in the shooting that happened one week ago. He appeared in a Lee County courtroom through a video call as he remains in the jail held on $2 million bond.
Milby's attorney, Tom Murray, dropped a previously filed motion to change the trial judge. Judge Jacquelyn Ackert says Milby will be due back in court on June 7 for a preliminary hearing.
Milby's attorney spoke to reporters following court Wednesday responding to reports that the 19-year-old's mother, Julie, should not have been able to own a weapon due to her criminal history. Illinois State Police say the gun used in the shooting was purchased by the mother in 2012. Murray says his client had a valid FOID card when she purchased the weapon.

UPDATE: DIXON, Ill. (WIFR) - Illinois State Police look for more details in the Dixon High School shooting including how suspected shooter, 19-year-old Matt Milby, had access to the weapon used in the shooting.
Investigators say the 9mm semi-automatic rifle used last Wednesday was purchased by Milby's mother, Julie, in 2012. A report by WGN, in Chicago, alleges she should not have been able to purchase a gun following a 1991 conviction of felony battery and resisting an officer with violence in Florida.
Milby's attorney, Tom Murray, told WGN he believes the gun was purchased legally in Illinois with a FOID card.
Milby, a former student of Dixon High School, pleaded not guilty to three counts of aggravated discharge of a firearm on Friday. He is currently held in the Lee County Jail on $2 million bond. He will be back in court for a hearing on Wednesday.
Milby is considered innocent until proven guilty.
UPDATE: DIXON, Ill. (WIFR) - At his first court appearance, suspected shooter Matt Milby pled not guilty to all charges.
After allegedly opening fire Wednesday at Dixon High School, Milby has 3 counts filed against him for aggravated discharge of a firearm. His bond is set at $2 million, but his defense attorney, Thomas Murray, tried to reduce that number to half a million dollars.
Lee County Judge Ronald Jacobson denied the defense's motion to lower bail. The prosecution argues Milby has already shown willingness to open fire, and would be a threat to public safety.
Milby appeared in court through a video call as the judge explained all three charges. His attorney says what happened Wednesday has not only changed the lives of his client's family but of the Dixon community.
"Matt is the only one that took a physical injury in this incident. There's a lot of emotional injury for sure but, Matt's the only one that had a physical injury in this incident. So in that sense, this community here is very fortunate," said Thomas Murray, Milby’s Defense Attorney.
The Lee County State's Attorney requests if Milby is released, that he can't have any contact while in or out of custody with Mark Dallas or Coach Andrew McKay, can't go within 100 yards of Dixon High School and is ordered to wear a GPS monitor.
Again, Milby faces charges of aggravated discharge of a firearm to a police officer, (identified as school resource officer Mark Dallas), aggravated discharge of a firearm to a school employee (identified as Andrew McKay, a gym coach at the school) and aggravated discharge of a firearm to an occupied building (Dixon High School).
Based on his charges, Milby could spend up to 120 years behind bars for the three class X felonies.
Milby will be in court at 9 a.m. on Wednesday, May 23 in front of Judge Ackert for a preliminary status hearing.
