Assistant State's Attorney Lorraine Scaduto said Crawford was working as a Safe Passage worker in the 1300 block of West 111th Place about 4:15 p.m. when he got into an altercation with a group of teens. He then followed the group and opened fire, striking a 17-year-old girl in the chest with a bullet that lodged between her rib cage and lung, Scaduto said.
