A month after two women were hit by gunfire while sitting in the bleachers during a White Sox game at Guaranteed Rate Field, the shooting that stunned the city and made news around the country appears no closer to being solved than it was in the hours after the incident, sources said.

       Rumors and hearsay, peddled largely by content aggregators on social media, have done little to quell speculation about the shooting — which, in the nearly 150-year history of Major League Baseball, is believed to be perhaps just the fourth instance of a fan being shot while inside a big league ballpark.

       Investigators have been weighing whether the woman who sustained the more severe injuries was somehow able to bring a gun into the stadium that later discharged while she was in the left field bleachers, according to police sources not authorized to speak publicly about the investigation. That woman has not been cooperative with Chicago Police Department investigators in the weeks since she was shot, sources said.
