DNA ties ex-Chicago detective to 1960 murder of 8-year-old girl

Chicago police used recently discovered DNA evidence to identify Thomas McInerney, a former CPD homicide detective who died in 2006, as the killer of Gloria Kowalewicz in 1960. The case is a cold-case breakthrough, but the suspect is deceased, so no prosecution will follow. It matters as a notable law-enforcement development highlighting advances in forensic DNA and the legacy of historical misconduct.
