A seventh person has died from injuries suffered in Monday’s Fourth of July holiday parade mass shooting in Highland Park, north of Chicago.

The seventh person died Tuesday at Evanston Hospital. Six were killed Monday and dozens of others were injured after a man perched on the roof of a nearby building opened fire on the crowd watching the Independence Day parade.

Robert E. Crimo III, 22, of Highland Park, remains in police custody over the shooting though he has not yet been charged with a crime. At a Tuesday news conference, police also said they had not yet determined a motive.

But we do believe Crimo preplanned this attack for several weeks,” Lake County Deputy Chief Christopher Covelli said Tuesday.

Covelli said that after shooting more than 70 rounds of ammunition from a high-powered rifle at parade-goers from a nearby rooftop, the shooter exited the roof, dropped his rifle and blended in with the crowd dressed in women’s clothing as he made his escape.

“He walked to his mother’s home, who lived in the area, and blended right in with everyone else as they were running around, almost as if he was an innocent spectator as well,” Covelli said, adding that authorities think he was in part trying to cover his facial tattoos to mask his identity.

At his mother’s home, Crimo borrowed her vehicle, Covelli said.

Hours later, after investigators issued an alert offering details on the car Crimo was believed to be in, an alert North Chicago police officer spotted the vehicle and called for backup.

“They were able to safely apprehend Crimo with no injuries to the officers,” Covelli said.

The shooter allegedly scaled a ladder to the rooftop and opened fire on the crowd of parade watchers shortly after 10 a.m. Monday in the north Chicago suburb.

Highland Park Police Chief Lou Jogmen said Monday night Crimo was in police custody.

“The officers that spotted the vehicle attempted to conduct a traffic stop on that subject, and the subject did flee,” Jogmen said. “A brief pursuit went on at Wesley and 41 in Lake Forest and the subject was taken into custody without incident.”

The shooting victim’s ages range from 8 years old to 85 years old. Highland Park Hospital official Dr. Brigham Temple announced that “four to five” of the victims were children.

Temple said that only two of the 26 victims who were transported to Highland Park Hospital are still at the hospital. All others have been transferred or released.

Five people died at the scene and a sixth victim died at a hospital, Lake County Coroner Jennifer Banek said.

The parents of accused Highland Park, Illinois, shooter Robert ‘Bobby’ Crimo III were “a problem” and always the last to pick him up from his afterschool sports program, the suspect’s former coach told Fox News Digital.

“I remember the parents more than him because they were kind of a problem,” recalled Jeremy Cahnmann, who ran an afterschool sports program at Lincoln Elementary School. “There wasn’t a lot of love in that family.”

The accused shooter, 21, is in police custody after allegedly gunning down revelers at the Highland Park July 4 parade, killing at least six people and injuring more than 36.

Crimo was 9 or 10 when he was enrolled in Cahnmann’s Nerf football program, along with his younger brother. “Every week, the Crimos were the last kids there, and we’d have to call their parents to pick them up,” the former coach said, speaking of Crimo’s dad, Bob Crimo, 58, and his mom, Denise Pesina, 48.

“The kid was really quiet, really soft-spoken, never made an issue,” added Cahnmann, who now runs the Chicago-based company Brain Bash Trivia.

Pesina, however, was a handful, he said. “She got into it once with one of the heads of the program, she was yelling,” he recalled. “It seemed like her kids were a nuisance to her.”

The accused shooter, an aspiring rapper, grew up with his parents, younger brother and older sister on McDaniels Avenue in Highland Park, outside of Chicago.

Under the stage name “Awake the Rapper,” Crimo posted a disturbing music video in 2021 that featured drawings of a stick figure wearing tactical gear carrying out an attack with a rifle, and a newspaper clipping about Lee Harvey Oswald, who assassinated John F. Kennedy.

“The signs were there for a long time,” said a neighbor of Crimo. “There were always police cars at the house. The parents were arguing, fighting all the time.”

Pesina is a self-proclaimed energy healer with her company called Trilogy Energy Systems, according to her Facebook page. His father once ran for mayor and had a local sandwich shop, Bob’s Pantry and Deli, that has since shuttered.

“He was so nice, he always gave the kids free candy and treats,” the neighbor said.

The mom seemed unstable while the father was well liked in the community, locals told Fox News Digital.

At the time of the shooting, the younger Crimo was living with his father and uncle at a home in nearby Highwood. Neighbors said Pesina still lived in the Highland Park home, which had become an eyesore in the upscale suburb.

“I walk by the house every day, it looks like it should be condemned,” said a local. “The landscaping is seven-feet high. I was thinking to myself the other day, we should really do a welfare check.”

Cahnmann said he was stunned to learn of the mass shooting.

“I’m shocked,” Cahnmann said. “Obviously these things can occur anywhere anytime, but Highland Park is a very affluent suburb where you don’t think things like this will happen.”

Investigators believe the suspect planned “this attack for several weeks,” Chris Covelli, spokesperson for the Lake County Major Crimes Task Force, said in a news conference Tuesday. The suspect dressed in women’s clothing to help conceal his identity, Covelli said, blended in with the crowds as they fled the area, and went to his mother’s house.

Law enforcement have yet to establish a motive, but Covelli said there has been no information to suggest the attack was “racially motivated, motivated by religion or any other protected status.” There is no indication anyone else was involved, Covelli said.

The suspect was taken into custody soon after police publicly identified him Monday as a “person of interest” who the FBI said was “being sought for his alleged involvement in the shooting of multiple individuals” at Highland Park’s Independence Day parade.

The suspect took his mother’s vehicle, and a member of the community saw him, Covelli said. That individual called 911 and North Chicago police conducted a traffic stop and took him into custody.

Police previously said Crimo was 22 years old, but on Tuesday, said he is actually 21.

The suspect legally purchased the weapon he used in Monday’s shooting, Covelli said Tuesday, describing it as a “high-powered rifle” which shot high-velocity rounds. The weapon, which he described as “similar to an AR-15,” was purchased locally, Covelli said, within the Chicagoland area.

Investigators believe he fired more than 70 rounds over the course of the attack, Covelli said, and there is no indication the weapon was modified.

Crimo also legally purchased a second rifle found in his vehicle at the time he was apprehended, as well as other guns recovered from his home, which Covelli described as pistols.

Firearm evidence was found on the rooftop of a business near the shooting, Covelli said Monday, describing the gun as a “high-powered rifle.” At the time, authorities were working to trace the firearm to find out who purchased it and its origins, according to Bureau of Alcohol, Tobacco, Firearms and Explosives spokesperson Kim Nerheim.

The expedited trace of the firearm was “a major investigative lead,” Covelli said Tuesday, and helped identify the suspect along with witness statements and videos from the community.

A total of 39 patients were treated at four NorthShore University HealthSystem hospitals, according to spokesperson Jim Anthony, who said nine patients remained hospitalized as of Tuesday afternoon. Four are in good condition, four are in stable condition, and one was in critical condition.

Eight of the nine patients suffered gunshot wounds, including the critical patient, a 69-year-old man, Anthony said.

Police in Highwood — the suspect’s hometown, just outside Highland Park — had no prior crime-related interactions with Crimo, according to Chief Dave Wentz.

The only contact the department had with Crimo involved a noncriminal incident where Crimo was present when he was a juvenile, Wentz said.

“We literally have nothing on him,” Wentz said. “He was not potentially involved in anything.”

He posted violent imagery online

The suspected shooter posted music on several major streaming platforms under the pseudonym Awake the Rapper, and he apparently made and posted music videos online featuring ominous lyrics and animated scenes of gun violence.

In one video titled “Are you Awake,” a cartoon animation of a stick-figure shooter resembling the suspect’s appearance is seen wearing tactical gear and carrying out an attack with a rifle. Crimo, seen with multicolored hair and face tattoos, narrates, “I need to just do it. It is my destiny.”

In another video titled “Toy Soldier, a similar stick-figure resembling the suspect is depicted lying face down on the floor in a pool of his own blood, surrounded by police officers with their guns drawn.

Law enforcement is reviewing the videos posted online, Covelli said at Tuesday’s news conference, noting police had not previously been made aware of them. “We’ll look at them and see what they reveal.”

Several of the suspect’s online postings “reflected a plan and a desire to commit carnage for a long time in advance,” Mayor Rotering said in an interview with NBC’s Hoda Kotb on “Today.

“And it’s one of those things where you step back and you say, what happened? How did somebody become this angry and hateful,” she said, “to then take it out on innocent people who literally were just having a family day out?”

YouTube and Spotify removed content tied to the suspect from their platforms, the companies confirmed Tuesday. They declined to answer questions about whether the content had been flagged or previously reported for violations of their respective terms of service. The companies also declined to say precisely when they removed the suspect’s content.

CNN has also reached out to Apple Music, Amazon Music, Tidal and Pandora with similar questions, but the companies have not yet responded.

His uncle says he saw no warning signs

Highland Park Mayor Nancy Rotering knew the suspect when she was his Cub Scout pack leader, she said, telling CNN, “Many years ago, he was just a little boy, a quiet little boy that I knew.”

“It breaks my heart. I see this picture and through the tattoos, I see the little boy,” she said. “I don’t know what got him to this point.”

The suspect’s uncle, Paul A. Crimo, was “heartbroken” to learn his nephew was believed to be responsible for Monday’s shooting, telling CNN,” There were no signs that I saw that would make him do this.”

The suspect lived in an apartment behind a house in Highwood, owned by his father, said Paul Crimo, who also lives at the house. He last saw his nephew Sunday evening, he said, sitting on a recliner in the house and looking on his computer.

“Everything was as normal,” he said.

To Paul Crimo’s knowledge, his nephew did not have a job, he told CNN, though he worked at Panera Bread before the Covid-19 pandemic. Paul Crimo said he had never seen the suspect engage in violence or concerning behavior. He didn’t know of his nephew’s political views, either, describing him as a “quiet” person.

“He’s usually on his own. He’s a lonely, quiet person. He keeps everything to himself.”

The suspect’s father and Paul Crimo’s brother, Robert Crimo Jr., previously ran for mayor, he said. “We are good people here, and to have this is devastating.”

“I’m so heartbroken for all the families who lost their lives,” Paul Crimo said.
