It all began with a car chase in Cicero, that turned into a shootout Sunday.

Witnesses said they saw a white car chasing down a black car in Cicero; the black car crashed into two other vehicles at the border in Chicago, and then masked gunmen began firing near West Roosevelt Road and Cicero Avenue.

First responders got to the scene around 12:30 p.m. A total of six people were injured, and one person was killed.

A Cicero spokesperson said at least four people were shot, and one of those victims died on the scene.

The Cook County Medical Examiner’s Office identified the man killed as 19-year-old Justin Washington, Jr. of Chicago.

Cicero police believe the shooting “was not random,” and that Washington was targeted by two suspects who were in a second vehicle.

The Chicago Fire Department said three other people were injured in the incident.

Two people were transported in critical condition to Stroger Hospital.

Two others were taken to Mt. Sinai Hospital in serious condition. Another person was taken to Mt. Sinai Hospital in good condition.

A sixth person was transported to Loretto Hospital in good condition.

Two female victims have been released from the hospital.

One female victim remains stable.

A business owner who was in the area when the violence unfolded described what he saw.

“I heard an accident. I heard a couple loud bangs. And when I came to the front of the store, I heard multiple gunshots. Then I heard more, and then I heard more,” said Louis Rainone, the owner of Roosevelt Gold Exchange. “They just went to that side of the car, and just started shooting him up. I have cameras. I looked to see if everything was clear. The white car took off. Soon after, the police came, the ambulance, the fire truck. It’s been closed down ever since. All the businesses are closed. It’s just one thing after the other.”

It happened on a street that has become a pathway paved with ongoing tragedy, some said.

“Somebody can’t even walk to the drug store,” Rainone said. “It’s violence. It’s on an, almost, everyday basis. It’s becoming terrible.”
