Stella Lemon was an 87-year-old white female patient at Daniel Drake Memorial Hospital in Cincinnati, Ohio, whose death on March 16, 1987, became part of one of the most extensive hospital serial-murder investigations in American history. Contemporary reporting identified Lemon as one of the patients killed by hospital orderly Donald Harvey. According to the case record, Harvey gave Lemon cyanide approximately three or four weeks before she died. Later accounts describe the poison as having been placed in orange juice. Unlike a sudden, immediately obvious poisoning, Lemon survived for several weeks after receiving the cyanide before dying on March 16, allowing the killing to blend into the deaths of seriously ill patients being treated at Drake.
Lemon's death initially did not expose what Harvey was doing. By the time she died, he had already been killing patients at Drake for months, frequently using cyanide and sometimes other poisons. The breakthrough came through the death of another patient, John W. Powell, on March 7, 1987. Harvey had placed cyanide into Powell's gastric feeding tube. During Powell's autopsy the following day, the presence of cyanide was suspected, and laboratory testing confirmed the poison. Cincinnati police were notified, turning what might otherwise have been treated as another hospital death into a homicide investigation.
Investigators began examining Powell's food supply, questioning his wife and interviewing hospital employees. During those interviews, Harvey's name surfaced because of the circumstances surrounding his earlier departure from employment at the Cincinnati Veterans Administration hospital. Hospital workers were volunteering for polygraph examinations, and Harvey initially volunteered as well, but he called in sick on the day he was supposed to take the test. Detectives Jim Lawson and Ron Camden subsequently questioned him. During that interrogation Harvey admitted putting cyanide into Powell's feeding tube, claiming that he had done it because he felt sorry for Powell and his family. At first, however, he denied having killed anyone else.
Harvey was indicted on April 6, 1987, for the aggravated murder of Powell, and public defender William Whalen was appointed to represent him. As investigators and journalists examined other suspicious deaths at Drake, the case widened dramatically. Nurses reportedly supplied information about deaths they believed were connected to Harvey, and an examination of the pattern of fatalities showed similarities between the deaths and his work schedule. Faced with the possibility that prosecutors could uncover numerous additional murders and seek the death penalty, Harvey and his attorney entered negotiations for a comprehensive plea agreement.
The agreement required Harvey to disclose the killings he had committed in exchange for prosecutors taking the death penalty off the table. Stella Lemon's poisoning was among the murders ultimately attributed to him. Contemporary UPI reporting listed Lemon as the 24th victim in the group of aggravated-murder cases to which Harvey pleaded guilty, stating that she had been given cyanide three or four weeks before her March 16 death. The same reporting showed the scope of the case: Harvey pleaded guilty to 24 aggravated murders, four attempted aggravated murders and one felonious assault involving victims in and around Cincinnati.
There was therefore no unresolved unknown suspect in Lemon's death. Donald Harvey was identified as her killer, confessed as part of the broader investigation, and accepted criminal responsibility through his guilty pleas. Lemon's killing fit the pattern that investigators uncovered at Drake: a hospital employee with direct access to vulnerable patients secretly introducing lethal substances into food, drinks, feeding tubes or other medical routes, allowing deaths to appear connected to the patients' existing illnesses rather than deliberate poisoning. In Lemon's case, the cyanide did not kill her immediately; she remained alive for weeks before dying, further obscuring the connection between the poison and her death.
Harvey did not go through a conventional murder trial for Lemon's death because the case was resolved through the plea agreement. In August 1987 he formally pleaded guilty to the Hamilton County charges, including the series of aggravated murders encompassing Lemon's killing. The court imposed three consecutive life terms under the agreement, effectively ensuring that he would remain imprisoned for decades. Additional investigations continued after those pleas, producing still more murder and attempted-murder charges connected to Drake Hospital. By 1988, Harvey had been convicted in Hamilton County of 28 murders and seven attempted murders, with additional sentences imposed concurrently with the life terms he was already serving.
The criminal reckoning extended beyond Ohio. Investigators also examined Harvey's earlier employment at Marymount Hospital in Kentucky, where he confessed to additional patient deaths dating to the 1970s. A Kentucky grand jury ultimately returned eight murder indictments and one voluntary-manslaughter indictment in corroborated cases. Harvey pleaded guilty to all nine counts and received life sentences for the murders plus a 20-year sentence for manslaughter, to be served concurrently with his Ohio punishment. Lemon's death thus emerged not as an isolated hospital homicide but as one episode in a killing career spanning years, multiple medical institutions and dozens of victims.
