The man accused of killing seven and shooting dozens at the Highland Park Fourth of July parade appeared in court Tuesday and his attorney said a trial date is expected to be set later this year.

Robert E. Crimo III, 22, of Highwood, faces 21 counts of first-degree murder, 48 counts of attempted murder and 48 counts of aggravated battery with a firearm.

Crimo appeared alongside his attorneys Gregory Ticsay and Anton Trizna, both public defenders, during a case management hearing Tuesday morning.

The hearing was held before Lake County Judge Victoria Rossetti.

Lake County Assistant State’s Attorney Ben Dillon, who is the chief of the Violent Crimes Unit, said his office has turned over an additional approximately 3,700 pages of material to the defense as part of the discovery process.

Prosecutors have filed subpoenas for medical records and other information as part of their investigation but are still awaiting some of those records. Additional lab reports from the FBI are also being sought.

Crimo’s parents attended the Tuesday hearing, which lasted only a few minutes, and sat behind their son.

Rossetti set the next case management conference for September 11.

Trizna said a trial date can likely be set at the September court hearing, which is when prosecutors believe the discovery process will be completed by.

Crimo has been held in the Lake County Jail without bond since July 6.

The 22-year-old’s father, Robert Crimo Jr., 58, of Highwood, was charged in mid-December with seven counts of reckless conduct causing great bodily harm.

Prosecutors and Highland Park police allege that Crimo Jr. was criminally reckless at the time that he helped his son obtain a Firearm Owners Identification (FOID) card.

Prosecutors said that helping his son obtain a FOID card was a contributing cause to the harm suffered by the murder victims in the July 4 mass shooting in Highland Park.

The man’s son, Crimo III, was under 21 when he sought to obtain the FOID card and required his father’s participation in the application process.

Prosecutors previously said Crimo admitted to “looking down his sights” of his Smith & Wesson M&P 15 semi-automatic rifle before opening fire on the crowd on July 4 near Second Street and Central Avenue in Highland Park.

Crimo told investigators he fired two full 30-round magazines before loading a third 30-round magazine and firing, Dillon said.

Seven people were killed and dozens of others were shot. 83 spent shell casings were recovered at the scene.
