Hundreds of people fled the shooting in Highland Park, about 25 miles north of Chicago, and triggered a police response from local, county and state officials. The extent of the injuries was not known.
One parade attendee, Miles Zeremsky, said he heard about 20 to 30 gunshots, two in a row of gunfire, at about 10:20 a.m. whistle, 20 minutes after the parade began. He said that a hail of bullets created a stampede as people fled. He told CNN he saw several people on the ground covered in blood and described the scene as chaotic.
“When the shooting started, my crew and I were gathering at the beginning of the parade. Me and my team are safe,” he said.
Video taken by a witness, Hugo Aguilera, shows an ambulance rolling down the parade route and a police car with sirens as people gather on a grassy pavement. Aerial video from CNN affiliate WLS shows abandoned lawn chairs up and down the parade route amid heavy police presence.
It was scheduled to begin at 10 a.m. CT at the intersection of Laurel and St. John’s Avenues, and continue north on St. John’s Avenue and then west on Central Avenue and to Sunset Park, the city said.
