Police said officers brought in a person of interest Friday to be questioned about the shooting. On Saturday, Cook County State’s Attorney’s office said, “the evidence was insufficient to meet our burden of proof to file murder charges at this time.” They said that the Chicago Police Department agreed with this decision.
