Highland Park (US), Jul 6 (AP) The man charged with killing seven people at an Independence Day parade confessed to police that he unleashed a hail of bullets from a rooftop in suburban Chicago and then fled to the Madison, Wisconsin, area, where he contemplated shooting up an event there, authorities said Wednesday.

The suspect turned back to Illinois, where he was later arrested, after deciding he was not prepared to pull off a shooting in Wisconsin, Lake County Major Crime Task Force spokesman Christopher Covelli said at a news conference following a hearing where the 21-year-old man was denied bond.

The parade shooting left another American community — this time affluent Highland Park, home to about 30,000 people near the Lake Michigan shore — reeling. More than two dozen people were wounded, some critically, and hundreds of marchers, parents and children fled in a panic.

Covelli said it did not appear that the suspect had planned another attack in Wisconsin, but fled there, saw another Independence Day celebration and “seriously contemplated” firing on it. The assailant had ditched the rifle he used in Illinois, but he had another rifle and about 60 more rounds with him, according to Covelli.

Police later found his phone in Middleton, Wisconsin, which is about 135 miles (217 km) from Highland Park.

For hours before his arrest, police warned that the gunman was still at large and that he should be considered armed and dangerous. Several nearby cities canceled events including parades and fireworks.

Lake County Assistant State's Attorney Ben Dillon said in court that the gunman “looked down his sights, aimed” and fired at people across the street. He left the shells of 83 bullets and three ammunition magazines on the rooftop.

Some of the wounded remained hospitalised in critical condition, Covelli said, and the death toll could still rise.

Lake County State's Attorney Eric Rinehart said he planned to bring attempted murder and aggravated battery with a firearm charges for each individual hurt.

“There will be many, many more charges coming,” he said at a news conference, estimating that those charges would be announced later this month.

The suspect, Robert Crimo III, wore a black long sleeve shirt as he appeared in court by video. He showed little emotion as the prosecutor described the shooting and said little besides telling the judge that he did not have a lawyer.

On Tuesday, Thomas A Durkin, a prominent Chicago-based lawyer, said he would represent Crimo and that he intended to enter a not guilty plea to all charges. But Durkin told the court Wednesday that he had a conflict of interest in taking the case. Crimo has been assigned a public defender.

Rinehart also left open the possibility of charging Crimo's parents, telling reporters that he “doesn't want to answer” that question right now as the investigation continues.

Steve Greenberg, the lawyer for Crimo's parents, told The Associated Press that the parents aren't concerned about being charged with anything related to their son's case.

Questions also arose about how the suspect could have skirted Illinois' relatively strict gun laws to legally purchase five weapons, including the high-powered rifle used in the shooting, despite authorities being called to his home twice in 2019 for threats of violence and suicide.

Police went to the home following a call from a family member who said Crimo was threatening “to kill everyone” there. Covelli said Tuesday police confiscated 16 knives, a dagger and a sword, but said there was no sign he had any guns at the time, in September 2019.

Police in April 2019 also responded to a reported suicide attempt by the suspect, Covelli said.

Crimo legally purchased the rifle used in the attack in Illinois within the past year, Covelli said. In all, police said, he purchased five firearms, which were recovered by officers at his father's home.

The revelation about his gun purchases is just the latest example of young men who were able to obtain guns and carry out massacres in recent months despite glaring warning signs about their mental health and inclination to violence.

Illinois state police, who issue gun owners' licenses, said Crimo applied for a license in December 2019, when he was 19. His father sponsored his application.

The state police have defended how the application was handled, saying that at the time “there was insufficient basis to establish a clear and present danger” and deny the application, state police said in a statement.

Investigators who have interrogated the suspect and reviewed his social media posts have not determined a motive or found any indication that he targeted victims by race, religion or other protected status, Covelli said.

The gunman initially evaded capture by dressing as a woman and blending into the fleeing crowd, Covelli said.

In 2013, Highland Park officials approved a ban on semi-automatic weapons and large-capacity ammunition magazines. A local doctor and the Illinois State Rifle Association quickly challenged the liberal suburb's stance. The legal fight ended at the U.S. Supreme Court's doorstep in 2015 when justices declined to hear the case and let the suburb's restrictions remain in place.

Asked whether Crimo's case demonstrates flaws in state law, Rinehart said that “the gap in the state's gun laws would be that we don't ban assault weapons.”

Under Illinois law, gun purchases can be denied to people convicted of felonies, addicted to narcotics or those deemed capable of harming themselves or others. That last provision might have stopped a suicidal Crimo from getting a weapon.

But under the law, who that provision applies to must be decided by “a court, board, commission or other legal authority.”

The state has a so-called red flag law designed to stop dangerous people before they kill, but it requires family members, relatives, roommates or police to ask a judge to order guns seized.
