Robert H. Crockett was an 80-year-old patient who died in Cincinnati, Ohio, on June 29, 1986. His death was later attributed to cyanide poisoning and is listed among the victims tied to hospital worker Donald Harvey. Reports indicate cyanide was introduced into Crockett’s intravenous line, allowing the poison to enter his bloodstream while he was already receiving medical care.

At the time of Crockett’s death, his decline did not provoke immediate suspicion; it fit a pattern seen in several Cincinnati hospital deaths that were initially judged to be medically explainable. Investigators only began to connect such deaths after an autopsy in March 1987 found cyanide in another patient, John W. Powell, which led to a probe that implicated Harvey. Harvey later confessed to numerous killings, including the poisoning of Crockett, and was prosecuted in Ohio under plea agreements that produced multiple consecutive life sentences.

Did anyone who knew Robert Crockett notice unusual events around his care in late June 1986?
