Former Chicago Detective Identified as Killer in 1960 Murder of 8-Year-Old Gloria Kowalewicz
By Drooid · · How we work
Core Event
Chicago police announced that modern forensic analysis has linked former homicide detective Thomas F. McInerney Jr. to the 1960 abduction and shooting of Gloria Kowalewicz, who was eight years old when she vanished while walking to morning Mass on Nov. 12, 1960. A fingerprint recovered from the strap of the girl’s white communion purse and DNA recovered from items at the scene matched McInerney, who retired from the Chicago Police Department in 1987 and died in 2006.
Background & Context
Gloria Kowalewicz disappeared shortly before 8 a.m. while heading a few blocks from her home to St. Mary of Mt. Carmel Church. Her body was discovered roughly four hours later in a ditch within a forest preserve southwest of Chicago. Investigators collected a bullet, the victim’s coat, shoes, and the white communion purse that held her prayer book. Despite interviewing more than 1,300 people, knocking on hundreds of doors, and questioning over a dozen individuals under polygraph, the case remained unsolved for more than six decades.
Preserved evidence—including the purse-strap fingerprint—was retained by the department and later re-examined with advanced DNA-genealogy tools that have previously solved cases such as the Golden State Killer. The FBI and Illinois State Police assisted in the recent analysis.
