At least 15 shot, 2 fatally, in South Side mass shooting in ‘makeshift pop-up tow company,’ top cop says

In response to a question, Brown said investigators had heard a rumor that someone left and came back and began shooting, but he said authorities were “unable to confirm that rumor at this point. It’s still so early, particularly with some of the witnesses in surgery right now that we haven’t been able to talk to.”
