A guy armed with a high-powered rifle opened fire from a rooftop during a Fourth of July parade in the Chicago neighborhood of Highland Park on Monday, killing six people and wounding more than 36. According to the police, the suspect was apprehended.

Police verified the capture of 22-year-old Robert E. Crimo III.

A video from the Chicago station of ABC News depicts police encircling a vehicle and Crimo exiting the car with his hands high. Crimo is prone on the ground before his arrest by the police.

Highland Park Police stated that charges would be brought.

The gunfire forced toddlers to abandon tricycles and parents to flee with their children, transforming a patriotic civic display into a scene of frantic mayhem.

Richard Kaufman, a retired physician across the street from where the gunman opened fire, described the sound as resembling fireworks and said he heard approximately 200 rounds.

"It was utter chaos. A stampede. There were infants in the air. Individuals were diving for shelter "he claimed. People were tripping over one another while covered in blood.

The police have no motive for the shooting.

Jim Anthony, a spokesman for the NorthShore University HealthSystem, stated that over 36 people were injured, primarily by gunfire. The ages of the 26 individuals brought to the hospital in Highland Park varied from 8 to 85, according to emergency room physician Brigham Temple.

The New York Times identified one of the victims as 76-year-old Nicolas Toledo, who was in a wheelchair and did not want to join the parade. However, his limitations required that someone constantly accompany him, and his family did not want him to miss the occasion.

"We were all in shock," Xochil Toledo, his granddaughter, said. We believed it to be part of the parade.

At least one of those killed was a Mexican national, according to a tweet from a top Mexican Foreign Ministry official.

After a massacre on May 24 that murdered 19 schoolchildren and two teachers at an elementary school in Uvalde, Texas, and an incident on May 14 that killed ten people at a grocery store in Buffalo, New York, gun violence is fresh in the minds of many Americans.

Children holding American flags, riding tricycles, and traveling in wagons drawn by parents froze as the crowd screamed and gunshots went out, as evidenced by social media video.

The Lake County Sheriff's Office has produced an online wanted poster for Crimo, which depicts a thin-faced, bearded man with facial and neck tattoos.

According to the police, the shooter gained access to the shop's rooftop using an unsecured alley ladder.

President Joe Biden and his wife Jill were "shocked by the senseless gun violence that has yet again brought grief to an American community on this Independence Day." he stated.

Biden stated that he has "surged federal law enforcement to assist in the urgent search for the shooter."

In his remarks, Biden referred to the recent bipartisan gun-reform legislation he signed and added, "I'm not going to give up fighting the epidemic of gun violence."

According to the US Census Bureau, Highland Park has a population of 30,000 and is almost entirely white. Jewish Telegraphic Agency estimates that around one-third of the population is Jewish.

The shooting will undoubtedly reignite the American debate over gun regulation and the question of whether stronger laws can prevent the numerous mass shootings that occur in the United States.
