She was shot in the chest near 18th and Wood streets while walking with friends in the Heart of Chicago neighborhood on Tuesday around 4 p.m. The shooting sprayed bullets at a busy food market, shattering windows.
"It was like one after another. Like he was standing literally outside, and I was looking at him. And he was shooting inside," said Norma Yanez, store employee.
According to witnesses, the incident began with a foot chase. A teenage gunman fired at another young man, and as they ran east on 18th Street, a stray bullet hit the girl in the upper chest.
"She was lying down on the stairway. So she was responsive, but yet in pain," said Sonia Yanez, owner, Meztisoy Food Market.
According to witnesses, the man who was the intended target ran into the store, and the gunman stood outside firing a handful of shots through the window. They say bullets hit a sign, a coffee machine and other items on a front table, but missed 15 or so people in the store.
"Some guy was coming towards me shooting, so I came into the store. And then the guy they were shooting at came in after me," said Norma Yanez, store employee.
Police have not offered a motive for the shooting, but some neighborhood residents say it may have been a gang-related incident.
Meanwhile, Mayor Rahm Emanuel and Chicago Police Superintendent Garry McCarthy plan to hold a news conference Wednesday announcing a decrease in the number of gang-related shootings.
