The father of Highland Park Fourth of July mass shooting suspect Robert Crimo III was arrested Friday in connection with the attack that killed seven people and wounded dozens more.
The Lake County State's Attorney's Office in Illinois said Robert Crimo Jr. faces seven counts of felony reckless conduct in connection with his son's Illinois Firearm Owner's Identification (FOID) Card.
"Parents and guardians are in the best position to decide whether their teenager should have a weapon. They are the first line of defense," Lake County State's Attorney Eric Reinhart said. "In this case, that system failed when Robert Crimo Jr. sponsored his son. He knew what he knew, and he signed the form anyway."
Authorities have previously said that Crimo III attempted suicide by machete in April 2019 and in September 2019 was accused by a family member of making threats to "kill everyone."
Prosecutors said Crimo Jr. signed his son's application for a FOID card on Dec. 16, 2019, when he was19.
At the time he signed the application, his son was under 21 and could not get a FOID card, and because of that could not legally purchase a firearm without his father's assistance.
In media interviews after the shooting, Crimo Jr. said he did not expect to face charges and did not believe he did anything wrong by helping his son get a gun license through the state’s established process.
Crimo III faces numerous charges, including murder, for the killing of seven people and wounding another 48 at the Highland Park July 4 parade. Authorities said he planned the attack for weeks, which sent parade goers and participants running for their lives. He has pleaded not guilty.
The seven victims who died in the shooting were identified as Jacki Sundheim, 63; Nicolas Toledo-Zaragoza, 78; Irina McCarthy, 35, and Kevin McCarthy, 37; Katherine Goldstein, 64; Stephen Straus, 88; and Edwardo Uvaldo, 69.
After the shooting, Crimo III tried blending in with the crowd and walked to his mother's home and borrowed her vehicle. He was arrested during a traffic stop.
His next court date is Jan. 31, 2023.
