Genene Jones has two murder convictions and one for attempted murder. The number of children she is suspected of killing runs past sixty. The reason the gap between those two figures is that wide is not a difficulty about evidence, or not only that. It is that the hospital where most of it happened ran an internal review, replaced the licensed vocational nurses on the unit with registered nurses, recorded no allegation against anyone, and said nothing to the clinic that hired her next.
Eight cases in this archive share that shape. In each of them an institution held enough to act and dealt with it inside the building: a rota was changed, a nurse was asked to resign, a reference was written that gave only the dates of employment, an internal inquiry cleared someone and told nobody. The killing then continued somewhere else, or continued in the same place for years. What the eight say together is something none of them says alone. The transfer was the mechanism, and the reference nobody wrote is the part that did the damage.
Jones qualified as a licensed vocational nurse in 1977 and worked in the paediatric intensive care unit at the Bexar County Medical Center Hospital in San Antonio from 1978. Infants on her shift suffered unexplained seizures and cardiac arrests, and a number of them died. Emergencies on her three-to-eleven rota became frequent enough that the shift acquired a name among the staff. The hospital noticed, and what it did about it was a reorganisation. The journalist Peter Elkind's assessment is that it had every reason to notify the authorities and decided not to come forward with what it knew. No administrator was ever charged. She went to work at a paediatric clinic in Kerrville, and within two months seven children there suffered respiratory arrests. On September 17, 1982 fifteen-month-old Chelsea McClellan died in an ambulance after a fatal injection of a muscle relaxant. When the San Antonio deaths were finally looked at, the hospital's records for the period had been destroyed under a document retention policy.
Charles Cullen worked at nine hospitals and a nursing home in New Jersey and Pennsylvania between 1984 and 2003, and the essential fact of his case is not what he did but what they did. Suspicion was raised at institution after institution. He was investigated internally, questioned by police at least once, found removing drugs, and dismissed or asked to resign. Every time, he was allowed to leave with a reference that gave his dates of employment and nothing else. The reason usually given was legal advice about defamation exposure. He has twenty-nine convictions, admitted to about forty killings in interviews, and said he had lost count and that it could be several hundred. Both states changed the law afterwards, requiring healthcare employers to report suspected wrongdoing and giving them immunity for honest references, which is a legislature saying out loud what the silence had cost.
Michael Swango admitted causing four deaths and the estimates run to sixty, and the case is taught in medical governance for the sequence rather than the poison. During his internship at Ohio State University Hospital in 1984, nurses on his ward reported that patients were collapsing after he had visited them, and one saw him inject something into an intravenous line. The hospital ran a brief internal inquiry, cleared him, and did not go to the police. He did not get his residency, and that was the whole of it. He poisoned co-workers with arsenic in 1985, was convicted of aggravated battery, served two years, and lost his licence in two states. Then he re-entered medicine on forged documents and an account of the conviction as a barroom brawl, and was taken on in South Dakota and at Stony Brook, which placed him at a veterans' hospital on Long Island without properly checking his application. Each institution passed him on and he went on killing at the next one.
Niels Hogel has eighty-seven convictions, two in 2015 and eighty-five in 2019, and the commission that examined the case concluded the real total is unknowable and probably exceeds three hundred. Both clinics he worked at had noticed the death rate on his shifts and the missing drugs. Oldenburg moved him on with a neutral reference in 2002 rather than reporting him. Delmenhorst delayed for weeks after suspicion crystallised. Germany is the one place in these eight cases where that decision was itself treated as a crime: seven former colleagues and managers at the two hospitals were prosecuted for failing to act, and several were convicted.
Orville Lynn Majors was a licensed practical nurse in the intensive care unit of a small rural hospital in Clinton, Indiana. Its ICU recorded 147 deaths between 1993 and 1995, against about thirty in the same period before he was hired. Nurses on the unit had begun saying among themselves that patients died when he was on, and one told a supervisor she was afraid to leave a patient alone with him. He was suspended in 1995, when the state licensing board acted on complaints. The hospital had the numbers and the staff had the suspicion, and what stopped him came from outside. He was convicted of six murders in 1999 and sentenced to 360 years; the prosecution's own estimate of the true figure was around 130.
Elizabeth Wettlaufer killed eight people in long-term care homes in Ontario between 2007 and 2016 using insulin, which in an elderly resident produces a death that looks entirely ordinary. No post-mortem was performed on any of them. She had been dismissed from her first nursing job in 1995 for stealing medication. She was dismissed from one home in 2014 for a medication error that had nothing to do with the killings, and was hired elsewhere. Nobody who let her go was concealing a murder, and that is the point of including her: the Gillese Inquiry found in 2019 that the long-term care system had no mechanism that would have found her, and what ended it was that she checked herself into a mental health centre in Toronto and told her doctors, who reported it.
Beverley Allitt's failure came earlier than the others, at the hiring. Through her training she was a persistent presenter at hospitals with injuries and complaints that turned out to have no organic cause, she failed a great deal of that training through absence, and she was taken on as a state enrolled nurse anyway. She was convicted in May 1993 of four murders, three attempted murders and six counts of causing grievous bodily harm on a children's ward, over about ten weeks. The Clothier Inquiry reported in 1994 on how she was ever employed, given a sickness record that should have been examined, and recommended screening nursing applicants for the pattern. Its recommendations were widely described afterwards as unimplemented. The record was in the building the whole time and nobody read it.
Lucy Letby was convicted of seven murders on a neonatal unit, and her case belongs here with the contest stated rather than left out. The convictions are among the most contested in modern English law: two applications to the Court of Appeal have been refused, a preliminary application has been with the Criminal Cases Review Commission since February 3, 2025, and in January 2026 the Crown Prosecution Service decided no further charges would be brought over nine more babies. What is not in dispute is the hospital's response, which the Thirlwall Inquiry was set up to examine. Consultants noticed the rise in deaths and collapses, raised it with management repeatedly through 2016, and were told to stop. Two of them were made to apologise to her. She was moved to clerical work in July 2016. Whatever the courts finally conclude about her, an institution that answers its own doctors that way is the subject of this article.
A sceptical reader will say the silence was rational, and for a while the law agreed. An employer who passes on a suspicion it cannot prove is exposed, and a reference confined to dates of employment is the advice a careful lawyer gives. That defence has been overtaken by events. New Jersey and Pennsylvania both changed the law afterwards, requiring healthcare employers to report suspected wrongdoing and giving them immunity for honest references, which means the exposure was fixable and was fixed once the cost of it was visible. Germany prosecuted seven people for the decision itself. The silence was not a legal necessity. It was a choice about who carried the risk, and in every one of these cases it was carried by the next patient.
Three cases in the archive show what the other route looks like, and all three took one person deciding to say something outside the institution. Waltraud Wagner and three colleagues killed elderly patients on a geriatric ward at the Lainz General Hospital in Vienna between 1983 and 1989; they were caught when a doctor overheard them laughing about a death in a tavern and reported it. Edson Isidoro Guimaraes was stopped when a hospital porter in Rio de Janeiro watched him fill a syringe with potassium chloride and inject a comatose patient, who died at once; his hospital had spent two years trying to account for the death rate in its intensive care unit, buying equipment and retraining staff, looking for a fault in a machine rather than a person. Once he was off the ward the deaths on it halved. Timea Faludi's case reached the Budapest police because the hospital's own director general reported a pattern of suspicious deaths, although rumours about her had circulated inside the building since 1998.
None of those three was solved by a system. A doctor in a bar, a porter in a doorway, and one administrator who picked up a telephone. Set against eight cases where the information stayed inside, that is not a reassuring comparison. It is the same finding twice: what these institutions were equipped to do was manage a personnel problem, and what nobody was equipped to do was say so to anyone outside.
