Delos Gedzius Sr., a hard-working pipefitter and former Marine, was found dead in his apartment in Merrionette Park, Illinois, on April 25, 1989. Authorities determined the cause of death to be a gunshot wound to the head and opened an investigation into the circumstances surrounding his death.

His wife, Debbie Gedzius, whose life was marked by the deaths of six children attributed to Sudden Infant Death Syndrome, drew scrutiny because of the unusual pattern of those deaths. The inquiry was described as being put on hold while authorities continued to examine the case.

Key facts about what happened in the apartment and who, if anyone, was responsible remain unresolved. Does anyone have information about Delos Gedzius Sr.’s last known contacts or about the state of the investigation in 1989?
