Dr. Shoo Lee's 1989 research on pulmonary vascular air embolism was cited to convict Lucy Letby, a nurse sentenced for murdering newborns. However, Dr. Lee claims his findings were misapplied, stirring debate about the integrity of the prosecution's evidence.

Disputed Evidence in High-Profile Case of Nurse Lucy Letby
Renowned Canadian neonatologist Dr. Shoo Lee questions the use of his research in convicting British nurse Lucy Letby of baby murders, asserting misinterpretations led to wrongful accusations.
In a shocking twist to one of Britain's most infamous murder trials, renowned Canadian neonatologist Dr. Shoo Lee is questioning the validity of the evidence that contributed to the conviction of Lucy Letby, a nurse accused of killing multiple infants in her care. Lucy Letby, a nurse at a neonatal unit in northern England, was found guilty of murdering 14 babies across two trials held in 2023 and 2024, leading to her life imprisonment.
This chilling case revealed allegations of a serial killer's methods, among them injecting babies with air, overfeeding them, and contaminating their feeds with insulin. Central to the prosecution's case was Dr. Lee's 1989 academic paper, which discussed a rare complication in newborns known as pulmonary vascular air embolism. The prosecution's lead expert witness referred to this research to assert that Letby had intentionally injected air into the veins of the victims, arguing that specific medical symptoms observed in the babies could only be explained by such acts.
However, Dr. Lee contends that his work was misinterpreted by the prosecution. In a recent interview, he expressed his concerns, stating, “What they were claiming was that this baby collapsed and had skin discoloration; therefore that equals air embolism. But that is not what the research shows.” He emphasizes that the claims made in court do not align with the conclusions of his study.
This challenge to the prosecution's expert evidence raises significant questions regarding the integrity of the trial and whether the conviction of Letby reflects a broader issue within the judicial system when it comes to forensic interpretations. As debates over the case continue, the implications of misinterpretation on justice and the lives that hang in the balance remain at the forefront of public discourse.
