The three victims were struck by gunfire from a single vehicle that fled the scene, according to a statement from a park spokesman. Dozens of emergency vehicles responded after the shooting. Two of the victims were still being evaluated at an area hospital, while a third victim refused treatment, according to the release. Their ages and genders were not released. Illinois State Police confirmed the shooting, saying they sent troopers to assist, but referred further investigation to Gurney police and the Lake County Sheriff’s Office. Officials at those offices did not immediately return calls for comment. The park was closed early with guests and team members departing under the direction of the Gurney Police Department. Law enforcement is investigating. The shootings come as public fears of a mass shooting remain high after the mass shooting at the Highland Park Fourth of July parade that left seven people dead and dozens more injured. Last weekend’s Bud Billiken Parade in Bronzeville had an increased police presence following concerns raised after the north suburban shooting that shocked the nation.
