Delos Gedzius Sr., a 33-year-old man of Polish ethnicity, died on April 1, 1989, in Alsip, Illinois. He had been living in Merrionette Park at the time. Neighbors said loud music and a blaring television came from his apartment for several days before his body was found. No arrests have been made and the death remains unsolved.

His death is part of a wider, disturbing sequence tied to his former wife, Deborah Anne Booe Fornuto, who was suspected in the deaths of six of their children. Those infants’ death certificates were later changed by the Cook County Medical Examiner’s Office from natural causes to indicate foul play, and a grand jury investigation followed.

What details might someone living in Merrionette Park or Alsip at the time remember that could help clarify what happened to Delos Gedzius Sr.?
