CHICAGO (WTVO) – Police have identified Robert “Bobby” E. Crimo III, 22, as a “person of interest” in the deadly mass shooting at Highland Park’s Fourth of July parade.

Police say Crimo is thought to be driving a 2010 silver Honda Fit with Illinois license plate DM80653.

Authorities say six people were killed and two dozen more injured after a gunman opened fire at a July Fourth parade in a Chicago suburb, authorities said Monday.

At an afternoon press conference, police confirmed five adults were killed at the scene. A sixth person was taken to an emergency room and died, but authorities did not give any further details.

A police spokesperson said that at least one of the victims transported to the hospital was a child with serious injuries. Hospital officials later said victims ranged from 8 to 85 years old, and four or five were children.

Highland Park Police Commander Chris O’Neill, the incident commander on the scene, urged people to shelter in place as authorities search for the suspect, described as a white male wearing a white or blue T-shirt.

Lake County Major Crime Task Force spokesman Christopher Covelli said at a news conference that the gunman apparently opened fire on parade-goers from a rooftop around 10:14 a.m., using a rifle that was recovered at the scene.

Covelli said police believe there was only one shooter and warned that he should still be considered armed and dangerous. He and O’Neill described the shooting as random.

Police have not released any details about the victims or wounded.

“This morning at 10:14, our community was terrorized by an act of violence that has shaken us to our core,” Mayor Nancy Rotering said at the news conference. “Our hearts go out to the families of the victims at this devastating time. 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.”

Hundreds of parade-goers – some visibly bloodied – fled the parade route after shots rang out, leaving their belongings behind. As of early afternoon, ominous signs of a joyous event suddenly turned to horror filled both sides of Central Street where the shooting occurred. Dozens of baby cartridges, some bearing American flags, abandoned children’s bikes, a helmet bedecked with images of Cinderella were left behind in their haste. Blankets, lawn chairs, coffees and water bottles were knocked over as people fled.

Police armed, some in camouflage gear and many clutching AR-style weapons continued to pour into the area.

Highland Park Police initially said in a statement early Monday afternoon that five people had been killed and 19 people were taken to hospitals. but those numbers were revised soon after at the news conference.

Illinois Gov. J.B. Pritzker released a statement Monday afternoon, saying:

“Today, I ask all Illinoisans to pray for the families who have been devastated by the evil unleashed this morning in Highland Park, for those who have lost loved ones and for those who have been injured. I also ask that we all pray for our first responders at all levels of government who are actively working to bring the suspect into custody, and whose bravery undoubtedly saved innocent lives on the scene. 

“There are no words for the kind of monster who lies in wait and fires into a crowd of families with children celebrating a holiday with their community. There are no words for the kind of evil that robs our neighbors of their hopes, their dreams, their futures. There are no words I can offer to lift the pain of those they leave behind. Please know that our state grieves with you, that MK and I grieve with you.

“But grief will not bring the victims back, and prayers alone will not put a stop to the terror of rampant gun violence in our country. 

I will stand firm with Illinoisans and Americans: we must – and we will – end this plague of gun violence.”

President Joe Biden on Monday said he and first lady Jill Biden were “shocked by the senseless gun violence that has yet again brought grief to an American community on this Independence Day.” He said he had “surged Federal law enforcement to assist in the urgent search for the shooter, who remains at large at this time.”
