A person of interest was in police custody early Wednesday morning in connection with a shooting that killed a teenage boy and critically wounded two men in Chicago’s Back of the Yards neighborhood.

The shooting happened at 7:40 a.m. Tuesday. Chicago police said a dark sport-utility vehicle pulled up in the 5000 block of South Throop Street, and someone in the vehicle got out and started shooting. The gunfire hit a 17-year-old boy who was walking outside and two men — ages 55 and 61 — sitting in a nearby vehicle.

The 17-year-old, identified by family as Pedro Ramirez, was taken to the University of Chicago’s Comer Children’s Hospital, where he was pronounced dead. Both men were taken to Stroger Hospital in critical condition.

The shooting happened just a few blocks from Peace and Education Coalition High School, an alternative high school for youth between the ages of 16 and 21.

“I heard the shots and I looked out the window and I saw him laying there, and I saw someone come to his aid,” a neighbor said.

She says she was left shaken following the gun violence near her home, but appreciates those who came to lay flowers, balloons, and candles at a memorial in his honor.

“I don’t think he deserved what happened to him. He was young, he had a lot of life to live,” she said.

The family identified Ramierz through GoFundMe, saying, “Pedro was a kind-hearted young man, loved by many and always willing to help. He was one of those people who truly leave a lasting impression.” His mother confirmed that he was an honor roll student at Tilden High School and was on the school’s soccer and volleyball teams.

Chicago Public Schools, in a statement, said, “All of us at Chicago Public Schools (CPS) are saddened to learn of the loss of this young person’s life and we extend our heartfelt condolences to the family, friends, school and community members impacted by this tragedy.”

The two men who survived the shooting drove to a nearby auto repair shop, where one of the workers, who asked to be identified only as Leo, saw them pull up in a red minivan.

“I thought it was a customer needing a tire repair, and when they pulled up at window level, the driver said, ‘I need assistance. Can you call paramedics?’ And I did so,” he said.

The minivan’s rear window had been shot out. Leo said the men’s injuries looked severe, and he acted quickly to get help.

About a mile and a half away from the shooting, police were seen investigating an SUV near 44th Street and Wolcott Avenue, where an AK-47-style assault rifle was lying on the ground nearby.

No charges had been announced in the case. It’s also not clear yet who was targeted in the shooting.
