Roger Evans, 74, was a patient at Daniel Drake Memorial Hospital in Cincinnati when he was deliberately poisoned on September 17, 1986.

Evans’s death initially appeared to be the decline of an already seriously ill hospitalized patient and did not by itself trigger the wider inquiry. After a later cyanide poisoning at Drake led to testing and an arrest, Harvey admitted to multiple killings and Evans’s death was treated as one of the intentional, premeditated homicides committed during Harvey’s employment at the hospital. Prosecutors listed Evans among the Drake victims when Harvey pleaded guilty to numerous counts of aggravated murder in August 1987.

Anyone who knew Roger Evans, his time at Drake Hospital, or has information about his final days is asked to come forward.
