A gunman perched on a rooftop opened fire on families waving flags and children riding bikes at a Fourth of July parade on Monday, killing six and wounding more than 36 in the Chicago suburb of Highland Park.
The gunman climbed to the roof of a business using a ladder in an alley, police said.
Hours later, police announced that they had a suspect in custody after 22-year-old Robert E. Crimo III surrendered to authorities.
Police said they did not know what the motive was for the shooting in Highland Park. The wounded ranged in age from 8 to 85, including four or five children.
President Joe Biden said he 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."
Biden referred in his statement to bipartisan gun-reform legislation he signed recently but said much more needed to be done, and added: "I’m not going to give up fighting the epidemic of gun violence."
