Lucy Letby is a former British neonatal nurse whose criminal convictions for the murder of seven infants and the attempted murder of seven others represent one of the most bitterly contested legal cases in modern UK history. While the courts have ruled decisively, a growing body of medical and journalistic scrutiny has raised fundamental questions about the evidence that underpinned the verdicts.
The case continues to generate intense public debate, fueled by high-profile documentary projects, a vocal campaign questioning the safety of the convictions, and ongoing investigations by official bodies and the press. Letby herself maintains her innocence, and her legal team has pursued further appeals.

Lucy Letby worked as a neonatal nurse at the Countess of Chester Hospital. Over a period spanning 2015 and 2016, a cluster of infant deaths and collapses on the unit led to a major police investigation. Letby was arrested in 2017 and subsequently charged.
Following a lengthy trial at Manchester Crown Court from October 2022 to August 2023, she was found guilty of seven counts of murder and seven counts of attempted murder. The prosecution argued that she had harmed the babies through methods including injecting air into their bloodstreams and administering insulin. She received 15 whole-life sentences.
A retrial on a single outstanding count of attempted murder in June 2024 resulted in a further conviction. The victims were five male infants and two female infants; seven other babies survived the attacks. As reported by the BBC, Letby’s initial appeals were rejected.

What is the Evidence and Key Testimony in the Lucy Letby Case?
The prosecution’s case relied heavily on statistical analysis of the clustering of deaths and collapses around Letby’s shifts, and on expert medical interpretation of the babies’ clinical events. A central piece of evidence was a note found in Letby’s home that read “I am evil, I did this,” which was introduced as an admission of guilt.
What did the note Lucy Letby wrote say?
A handwritten note discovered during a police search of Letby’s home contained the phrase “I am evil, I did this.” This note was presented to the jury as evidence of her consciousness of guilt.
What has Private Eye reported about the Lucy Letby case?
Private Eye magazine has published several investigative reports that question the strength of the medical evidence used to convict Letby. Their reporting has focused on the reliability of expert testimony and the statistical methods used by the prosecution, contributing to the public controversy surrounding the case.
A significant development came in 2025 when an international expert panel, convened by the Canadian neonatologist Dr. Shoo Lee, reviewed the medical records of the babies involved. The panel stated there was “no medical evidence to support malfeasance” and concluded that the deaths and injuries were consistent with natural causes or poor medical care. They specifically found no evidence that Letby had injected air into the babies’ bloodstreams.
This report directly contradicted the testimony of key prosecution witnesses, including Dr. Dewi Evans, whose professional credibility has since come under further scrutiny. The BMJ, the Guardian, and the New York Times have all reported on this conflict of medical opinion. The court outcomes, however, remain unchanged, as the BBC has noted.
The central controversy hinges on the reliability of expert medical interpretation. The original prosecution depended on rare clinical events being attributed to deliberate harm, while later experts have stated that interpretation was medically incorrect. The truth of the matter remains a subject of fierce legal and medical debate.
Why Are Some People Campaigning for Lucy Letby’s Innocence?
A substantial campaign has grown in support of Letby’s claims of innocence, driven largely by doubts about the medical evidence. A public petition seeking to overturn the convictions has gathered over 100,000 signatures. The campaign often argues that Letby was convicted on circumstantial evidence and disputed expert testimony rather than direct proof of harm.
The campaign’s arguments are amplified by the findings of the international expert panel and by investigative reporting from outlets like Private Eye and the BMJ. This has created a situation where a vocal public movement exists alongside the official legal position that the convictions are sound. The legal process continues with a fresh appeal application having been announced in 2025.

Background and Analysis of the Case
The Lucy Letby case sits at a complex intersection of forensic medicine, criminal psychology, and legal journalism. The central tension is between a criminal justice system that has delivered a final verdict and a scientific community that is deeply divided over the medical evidence that supported it. The Royal College of Physicians of Edinburgh has hosted events discussing the power and limits of expertise in the case, highlighting its significance for legal processes involving complex medical facts.
