CHICAGO (CBS) — A 6-year-old girl was killed and two teenagers were wounded Sunday morning when someone fired shots into the living room of a home in the Englewood neighborhood.

Police said that at about 6 a.m. Sunday, someone walked up to the front porch of a single-family home in the 7400 block of South Sangamon Street and fired shots inside, striking three people.

As WBBM Newsradio’s Steve Miller reports, the door to the home where 6-year-old Arianna Gibson was shot and killed has a bumper sticker reading “Don’t Shoot. I Want To Grow Up.”

Arianna died after she was taken to University of Chicago’s Comer Children’s Hospital, police said. She had been shot in the chest and the arm.

A 17-year-old boy was taken to John H. Stroger Jr. Hospital of Cook County and a 17-year-old girl was taken to Advocate Christ Medical Center in Oak Lawn. Police said both teens were in good condition.

The night before the shooting, there was a block party on the 7400 block of South Sangamon Street. Arianna was playing, jumping rope and having a good time at her grandmother’s home.

Arianna was sleeping on the couch when she and the two teenagers were shot.

Arianna’s grandmother, Christine Collins, sat on the steps, sobbing and shaking as she tried to figure out why someone would kill her granddaughter.

“Arianna, she was sweet. She loved to play. She loved to come over here and to be with me,” Collins said. “She came over here for the weekend with her brothers … and they had the block party.”

Arianna’s aunt, Linda Chatman, said “It’s just ridiculous, it’s stupid, you know, everybody killing these kids, you know, for no apparent reason. You know, if they’re looking for someone, you know, get that person. Don’t come kill a child who’s innocent, don’t know nothing, what’s going on. It’s just ridiculous.”

Arianna was supposed to have started school on Monday. Her family said she was excited and wanted to get her hair done for the first day of classes.
