What we know so far – NBC Chicago

It has been more than 24 hours since a deadly mass shooting at an event celebrating June 19 in a southwest Chicago suburb left more than 20 people dead.

While a lot happened in the hours that followed, several questions remain.

Here’s a look at what we know so far, as the investigation into what happened continues:

How did the filming go

Authorities say the shooting erupted around 12:25 a.m. Sunday during a scuffle near Hinsdale Lake Terrace in unincorporated Willowbrook. Police said officers were initially monitoring the celebration, but were called to respond to another 911 call.

Deputies were in an area near the intersection of Honeysuckle Rose Lane and Route 83 when they heard multiple gunshots.

Witnesses described a chaotic scene the day after the shooting.

“We were all out and the next thing you know, gunfire started. Everyone ran and it was chaos,” Craig Lottie said.

“As we were preparing to leave, we just started to hear gunshots behind us. So we fell,” said Marqeisha Avery, another witness.

How many shooters were there?

Police believe multiple guns were fired in the incident, but the total number of suspects who opened fire on the crowd remains unclear.

Authorities said Monday they were still processing ballistic evidence.

Police added that they are continuing to process evidence from the scene.

As of Sunday evening, authorities were still looking for suspects in the incident. They did not immediately respond to requests for comment on Monday.

Who were the victims?

Earlier Monday, the victim killed in the shooting was identified as 31-year-old Reginald Meadows. The DuPage County Coroner’s Office said Meadows died of a fatal gunshot wound to the abdomen following the tragic event.

Police said they were not releasing the identity or location of other victims “out of an abundance of caution” and for their safety.

A local hospital reported that it initially received 12 patients who were injured in the incident. Seven were treated and released, while five remained hospitalized.

What triggered the shooting?

Police only said the shooting erupted during a fight at the event, but have not yet released a motive.

The DuPage County Sheriff’s Office said in a statement Monday afternoon that their investigation remains active and ongoing as officers continue to search for witnesses and potential victims following the incident that has caused at least 23 people killed, including one fatally.

“Interviews of known witnesses and victims are continuing, and we are trying to locate other witnesses and victims who may not have sought medical attention for their injuries,” police said.

Where are things now?

Police said they have been investigating “non-stop” since the incident and the investigation is continuing.

The department added that it was continuing to process evidence, including what was left behind by the vehicles involved and video evidence from nearby businesses.

In the hours after the shooting, Illinois Governor JB Pritzker said he was “watching closely” what happened.

“…Gathering together for a holiday celebration should be a joyful occasion, not a time when gunfire erupts and families are forced to run for protection,” his statement read in part.

White House Press Secretary Karine Jean-Pierre tweeted Sunday afternoon that President Joe Biden is also offering assistance after the shooting.
