Witnesses were in disbelief that a shooting happened in the heart of downtown Chicago.

“I saw the trail of blood, and saw the commotion, and kind of feel that now the area’s sort of tainted. We thought this area was going to be protected from this kind of stuff. You don’t think it’s going to happen around here,” Sergio Castro said.

Police said the shooting appeared to be gang-related. Area Central detectives were investigating.
