CHICAGO — The man suspected of killing at least six people and injuring more than 30 others Monday morning during a Fourth of July parade in Highland Park planned the attack for several weeks before he climbed a fire escape ladder and fired on the crowd from the roof of a building, authorities said at a news conference Tuesday.
The alleged shooter, Robert “Bobby” E. Crimo III, 21, dressed as a woman in order to evade detection, according to Chris Covelli, a spokesman with the Lake County Major Crimes Task Force. After firing more than 70 rounds, he exited the roof, dropped the rifle, slipped into the crowd and went to his mother’s house, he said.
Covelli said investigators haven’t determined a motive.
