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.

Authorities said a man named as a person of interest in the shooting was taken into police custody Monday evening after an hourslong manhunt in and around Highland Park, an affluent community of about 30,000 on Chicago’s north shore.

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.

“It definitely hits a lot harder when it’s not only your hometown but it’s also right in front of you,” resident Ron Tuazon said as he and a friend returned to the parade route Monday evening to retrieve chairs, blankets and a child’s bike that he and his family abandoned when the shooting began.

“It’s commonplace now,” Tuazon said of what he called yet another American atrocity. “We don’t blink anymore. Until laws change, it’s going to be more of the same.”

The shooting occurred at a spot on the parade route where many residents had staked out prime viewing points early in the day for the annual celebration. Dozens of fired bullets sent hundreds of parade-goers — some visibly bloodied — fleeing. They left a trail of abandoned items that showed everyday life suddenly, violently disrupted: A half-eaten bag of potato chips; a box of chocolate cookies spilled onto the grass; a child’s Chicago Cubs cap.

“There’s no safe place,” said Highland Park resident Barbara Harte, 73, who had stayed away from the parade fearing a mass shooting, but later ventured from her home.

Highland Park Police Chief Lou Jogmen said a police officer pulled over Robert E. Crimo III about five miles north of the shooting scene, several hours after police released the man’s photo and an image of his silver Honda Fit, and warned the public that he was likely armed and dangerous. Authorities initially said he was 22, but an FBI bulletin and Crimo’s social media said he was 21.

Police declined to immediately identify Crimo as a suspect but said identifying him as a person of interest, sharing his name and other information publicly was a serious step.

Lake County Major Crime Task Force spokesman Christopher Covelli said at a news conference “several of the deceased victims” died at the scene and one was taken to a hospital and died there. Police have not released details about the victims or wounded.

Debbie Glickman, a Highland Park resident, said she was on a parade float with coworkers and the group was preparing to turn onto the main route when she saw people running from the area.

“People started saying: ‘There’s a shooter, there’s a shooter, there’s a shooter,’” Glickman told the AP. “So we just ran. We just ran. It’s like mass chaos down there.”

She didn’t hear any noises or see anyone who appeared to be injured.

“I’m so freaked out,” she said. “It’s just so sad.”
