(HIGHLAND PARK, Ill.) — A gunman opened fire on a Fourth of July parade in an affluent suburb north of Chicago on Monday, killing at least seven people and injuring more than three dozen others, including children.

Five of the victims died at the scene of the shooting in Highland Park, Illinois, while one died at a hospital, according to officials. On Tuesday afternoon, a seventh victim succumbed to their injuries at Evanston Hospital, officials said.

The Northshore University Hospital system, which includes Evanston, Glenbrook, Highland Park and Skokie hospitals, treated a total of 39 patients from the scene, according to hospital officials.

Highland Park Hospital admitted 25 people with gunshot wounds, 19 of whom were treated and discharged. The others were in “more serious condition,” said Dr. Brigham Temple, medical director of emergency preparedness.

The wounded ranged in age from 8 to 85, according to Temple. One child was taken to Evanston for further treatment and another was medically evacuated to the University of Chicago Hospital, about 30 miles south of Highland Park.

As of Tuesday, eight patients remained hospitalized in the Northshore facilities, officials said.
