Mayor Rahm Emanuel was among those offering condolences to the family of a 6-year-old girl killed the day before she was scheduled to start school.
Arianna Gibson was sleeping on her grandmother's couch the 7400 block of South Sangamon Street when the house was hit by gunfire. Two other teens were also wounded in the shooting.
A prayer vigil was held Monday in the girl's honor, but the victim's mother, Demitta Collins, and her grandmother were taken to nearby Liberation Christian Center to meet with Emanuel and the family's pastor.
"He said I don’t have to worry. My family don't have to worry," Collins said of her meeting with the mayor.
Police Superintendent Garry McCarthy expressed disgust Monday at a news conference while talking about the incident and revealed a potential break in the case.
"We have a person in custody who's being questioned," McCarthy said. "We have a lot of information we have to follow up on before we get that person charged. But right now it’s a very, strong, strong lead."
The two teens victims, A 17-year-old female and a 17-year-old man, were listed in good condition.
On Saturday, the whole block had gathered for a party. Arianna was among dozens of children who played with sidewalk chalk and ate barbecue ahead of their first day of school. She was scheduled to begin classes at Libby Elementary.
"Whoever hurt my baby are wrong for that. That was a little 6 year old. She didn't deserve this," Collins said.
