Around 2 a.m. one night in the summer of 2022, five friends walked out of a club in the Loop and got into an argument with a man who then pulled a gun. He fired a Glock pistol at them, one that had been illicitly converted into an automatic weapon capable of unleashing 20 rounds every second. A witness in a nearby apartment said the spray of bullets sounded like fireworks. Two people were killed — shot in the head and chest. Three others were hit but survived.
