WATCH: Police name ‘person of interest’ for 4th of July parade shooting in Highland Park

HIGHLAND PARK, Ill. (AP) — A gunman on a rooftop opened fire on an Independence Day parade in suburban Chicago on Monday, killing at least six people, wounding at least 30 and sending hundreds of marchers, parents with strollers and children on bicycles fleeing in terror, police said. The suspect remained on the loose hours later as authorities scoured the area.

Highland Park Police Chief Lou Jogmen said Monday afternoon that police have identified 22-year-old Robert E. Crimo III as a person of interest and cautioned he should be considered armed and dangerous. Police declined to answer questions about how they identified Crimo. Authorities described his car as a silver Honda Fit with an Illinois license plate DM 80653.

The July 4 shooting was just the latest to shatter the rituals of American life. Schools, churches, grocery stores and now community parades have all become killing grounds in recent months. This time, the bloodshed came as the nation tried to find cause to celebrate its founding and the bonds that still hold it together.

Mayor Nancy Rotering said the violence “has shaken us to our core,” adding, “On a day that we came together to celebrate community and freedom, we are instead mourning the tragic loss of life and struggling with the terror that was brought upon us.”
