Helen Metzger was 63 and living in the Cincinnati area when she died on April 10, 1983, after arsenic was placed in a pie she ate. Investigators later learned the poisoning was deliberate and premeditated; some accounts say it followed an argument between Metzger and her neighbor, Donald Harvey. Metzger suffered paralysis and hemorrhaging before her death and was buried at Vine Street Hill Cemetery in Cincinnati.

Metzger’s killing became part of a much larger investigation that unfolded after a 1987 hospital autopsy found cyanide in a patient. Police focused on Harvey, an orderly who had access to patients and also targeted people in his personal life. Prosecutors included Metzger among the aggravated-murder counts in the Ohio case, concluding arsenic in her pie caused her death. No second suspect has been identified; Harvey admitted to Metzger’s murder and to numerous other killings.

Did anyone who knew Helen or lived near her remember that neighborhood or the dispute with Harvey?
