CHICAGO (CBS) — A 20-month-old boy was killed, and his mother was grazed by a bullet, when they were shot while driving home from the laundromat Saturday afternoon in the Englewood neighborhood.

Chicago Police Chief of Operations Fred Waller said, shortly after 2 p.m., the boys’ mother was driving south on Halsted Street near 60th Street, on the way home from the laundromat, with the toddler in a child seat in the back of the car, when another car pulled up alongside them, and someone inside started shooting.

The boy was shot once in the chest, and a bullet grazed the mother’s head, according to Waller.

The mother, who is 22 years old, drove to St. Bernard Hospital, where her son was pronounced dead. She was later transferred to the University of Chicago Medical Center.

“It seems like just yesterday, it was actually last Saturday, I was in front of you all talking about a 3-year-old that was killed in the Austin community, and now here in Englewood, a 20-month-old was killed,” Waller said. “This is happening far too often. Too many times children are killed by senseless violence, and not only just children, but grown-ups also. When is this going to stop? When are we going to say enough is enough?”

Pastor Donovan Price said he consoled the boy’s mother and father as they grieved for their son.

“Today, I just want to sit on the side of the curb … like the mom was at one point. I just want to sit on the side of the curb, and shake my head, and cry,” Pastor Donovan Price said. “If you’re not mad, if you’re not outraged, if you’re not heartbroken about this, then what will you be heartbroken about, and do you have a heart?”

“It’s all bad. There’s a term ‘it’s all bad.’ Well, this, it’s all bad,” Price added. “I would like to see the silver lining, but this is all bad.”

Waller said the shooting did not appear to be random. He said detectives were working “feverishly” to review video footage from nearby cameras, and to canvass the area for witnesses.

No weapon has been recovered, but based on the shell casings at the scene, Waller said the shooter was using a handgun.

“No doubt we’ll catch the person who did it. We’ll catch the person who killed that 3-year-old. We’ll catch the person who killed this kid. But that’s not going to bring that kid back, and that’s not going to satisfy that family,” Waller said.

Multiple groups have offered rewards for information leading to the arrest and conviction of the shooter. The rewards total at least $39,000.

Mayor Lori Lightfoot, in a series of tweets on Saturday, noted a 17-year-old boy also was shot and killed on Saturday, writing “The pain of losing a child never goes away. … I am tired of the funerals. I am tired of burying our children.”

“It’s on all of us. It’s on all of us to find the courage to be a part of the solution,” she wrote. “It’s on all of us to double down on our all-hands-on-deck public safety efforts with police officers, street outreach teams, trauma support workers, community and faith-based partners. We must ask ourselves: “What are we each doing to make this a season of bounty, not tragedy?”

Chicago Police Supt. David Brown also issued a statement Saturday night:

“We ALL need to be outraged by the violence we are seeing in our city. This baby, and all of our residents, deserve better. This is not just a problem that Englewood needs to solve. This is not just a problem on the South Side or the West Side. We cannot compartmentalize the violence that is tearing families and communities apart. Someone knows something. For the sake of Chicago’s children, please come forward to help bring the trigger pullers to justice.”

The boy is at least the fifth child under age 10 to be shot in Chicago in the last week-and-a-half, and the second to be killed.
