More charges are expected, Lake County State’s Attorney Eric Rinehart said.Crimo, who appeared in court via Zoom for his first appearance Wednesday, showed no emotion as a prosecutor outlined the attack and read the victims’ names.Prosecutors said that Crimo confessed to Monday morning’s parade massacre.Crimo is accused of taking his legally purchased high-powered rifle and opening fire on paradegoers from a roof of a business.A witness reported seeing an individual with a gun on a building rooftop “scanning the ground with a gun,” Assistant State’s Attorney Ben Dillon said.On the rooftop, police discovered three empty 30-round magazines and 83 spent shell casings, prosecutors said.Crimo told police he wore women’s clothing during the shooting and used makeup to hide his facial tattoos and blend in with the crowd, prosecutors said. Crimo was apprehended at at traffic stop in Lake Forrest, Illinois, Monday evening. A second weapon, also purchased legally by Crimo, was found in the car, police said.Crimo was ordered held without bond. He is set to return to court for a preliminary hearing on July 28.He did not enter a plea during the appearance and was appointed a public defender.When the gunfire began at Monday’s parade, revelers fled in panic, leaving behind empty strollers, overturned chairs and half-eaten sandwiches.“Bodies were horribly, horribly, horribly injured from, you know, guns and bullets that were made for war — not for parades,” witness Dr. David Baum said of some of the victims.“The paramedics went quickly and assessed the damages — saw bodies that were blown apart and put a blanket over them quickly. And then went on to try and help other people,” Baum told ABC News. “These are injuries that nobody should have to see.”Authorities believe the massacre had been planned for weeks.No motive is known, police said. When asked by reporters if the gunman targeted anyone specifically, police said the “shooting appears to be completely random.”Copyright © 2022, ABC Audio. All rights reserved.
