'They're just shocked': Community holds vigil for 3-year-old killed in West Lawn road rage shooting

CHICAGO (WLS) -- Mateo Zastro, 3, was shot and killed on Friday night while riding in the back seat of his mother's car.

A community is holding a vigil for 3-year-old Mateo Zastro, who police said was killed in a West Lawn, Chicago road rage shooting.

Mateo was the victim of what police described as a road rage incident in Chicago's West Lawn neighborhood. On Monday evening, his family and their supporters gathered to honor him with a vigil near their home.

"It wasn't necessary to do what you did. You followed my path home," said his mother Veronica Zastro. "I wasn't following you."

Zastro's grief has given way to boiling anger. She, along with the crowd at the vigil, demanded whoever shot the child turn themselves in.

"And then you decided to plot against me and my babies, and I will not sleep until you are brought in. I will not sleep," Zastro said.

Mateo's siblings were in the car with him at the time of his death.

"These ones were in the backseat and when their baby brother dropped to the floor..." she recalled. "My son is scared to go back to school"

And while no arrests have been made, police made it clear that there is more than one person out there who can lead them to their shooter.

WATCH: CPD Supt. David Brown speaks after several children shot over weekend

CPD Supt. David Brown spoke after several children were struck by gunfire in Chicago weekend shootings.

"Based upon what we do have, I know I'm being a little bit cryptic, but we do have evidence to show that people out there know who committed this act and we ask for them to come forward, even if it is anonymously, through a tip," said CPD Chief of Detectives Brendan Deenhihan

Mateo was not the only child shot in Chicago this weekend. A 7-year-old boy is at Comer Children's Hospital, recovering from surgery after being struck in the leg on Sunday morning. He was also riding in the back of his parents' car.

The family was, according to police, arriving at a Roseland church, when they saw and followed a man who was allegedly breaking into a relative's vehicle. That man was arrested following the incident.

The mother of 7-year-old Legend Barr said he has undergone surgery after being shot this weekend and faces a long road to recovery.

"The 7-year-old is pretty resilient. He handled it like a champ. When you think of a seven year old being shot, what a terrible thing. But, he is doing fine right now, as fine as you can do after an incident like that," said CPD Deputy Chief Larry Snelling.

According to city data, as of Oct. 1st, 291 teens and children under 19 have been shot in Chicago so far this year. Thirty-nine of them have been killed.

And while police continue to tout a significant decline in overall shootings and homicides in the city relative to last year, the number of children shot and killed in Chicago, is as of Saturday, only down by one.
