Authorities in Lake County say the man suspected as the mass shooter at the Highland Park 4th of July parade planned his attack for weeks.
And he had prior contact with law enforcement. Lake County Major Crimes Task Force Spokesman Christopher Covelli says starting in April of 2019 they became aware of Robert Crimo III, and in September of 2019 they were told he had dangerous intentions.
The Illinois State Police say at the time of the September incident Crimo didn’t have a Firearm Owners Identification Card to revoke. And with no one willing to file an official complaint there wasn’t a way to prevent him from applying for a FOID card. And those knives were returned to his father.
Crimo later passed a background check and was granted a FOID card after being sponsored by his father.
