Parking lot shooting leaves 1 dead and at least 22 people hurt in suburban Chicago

“We know of 22 victims injured and one victim killed by gunfire. Several other victims were also injured while attempting to flee the area,” the sheriff’s office said in a statement. Authorities didn’t immediately release the conditions of those injured.

A motive for the attack wasn’t immediately known, and no one was arrested by early afternoon. Sheriff’s spokesman Robert Carroll said authorities were interviewing “persons of interest” in the shooting, the Daily Herald reported.

Police were at the strip mall before the shooting to monitor the gathering, but were called away because of a nearby fight, the sheriff’s office said. “They heard gunshots and immediately returned to the scene,” the sheriff’s office said.

“We transported numerous victims from the scene. Others just walked into area hospitals,” said Eric Swanson, deputy chief at the sheriff’s office.

Rick Wagner, who lives nearby, said there were at least 300 people in the lot by 10:30 p.m. “We’ve had multiple conversations with police” about large groups meeting there, Wagner told the Daily Herald.

A witness, Markeshia Avery, said it was a Juneteenth celebration. Monday is the federal holiday commemorating the day in 1865 when enslaved people in Galveston, Texas, learned they had been freed — two years after the Emancipation Proclamation.

“We just started hearing shooting, so we dropped down until they stopped,” Avery told WLS-TV.

Another witness, Craig Lotcie, said: “Everybody ran, and it was chaos.”

Illinois Gov. JB Pritzker said in a statement that he was monitoring the investigation.

“Gathering for a holiday gathering should be a joyful occasion, not a time where gunfire erupts and families are forced to run for safety,” Pritzker said.

The White House released a statement Sunday afternoon, saying that the “President and First Lady are thinking of those killed and injured in the shooting in Illinois last night. We have reached out to offer assistance to state and local leaders in the wake of this tragedy at a community Juneteenth celebration.”
