Irene Koutros, 41, was murdered in July 1973 in the underground garage at Grant Park in Chicago. Her death was one of several violent killings later linked to Lester Harrison, an offender active between 1970 and 1973 whose record included arrests for robbery and assault and documented mental-health issues. Some victims in that series suffered fatal stab wounds; Koutros was attacked in the same park garage that became a hunting ground for Harrison.

Harrison had previously been found incompetent for trial in other cases and was released multiple times before the crime spree ended. The series culminated with the August 13, 1973 killing of Judith Ott, an event that led to Harrison’s final capture after Ott’s husband, David Ott, tackled him near the scene. Harrison was later confined indefinitely as a sexual predator and deemed unfit for trial.

The circumstances around Koutros’s death underscore gaps in how a person with repeated violent behavior and mental illness was managed before more comprehensive confinement. If anyone knew Irene Koutros, her movements that July, or has information about Grant Park in 1973, please share what is known.
