New Evidence Challenges Lucy Letby Murder Convictions
The Facts
- The legal team for former nurse Lucy Letby—sentenced for poisoning babies in her care between 2015 and 2016—has submitted two major reports to the Criminal Cases Review Commission (CCRC) contesting her conviction; a 698-page expert analysis and an 86-page report by seven medical experts.
- In a summary report published on April 2, 2025, the panel of international experts asserted there was “no medical evidence to support malfeasance” and that the infants died of either “natural causes or errors in medical care.”
- A summary of the joint expert witness report on Baby F and L, compiled by the seven medical experts, concludes that new evidence “undermines the validity” of the insulin and C-peptide test results presented in court, arguing that these findings "cannot be safely relied upon."

The Spin
Narrative A
The evidence used to convict Lucy Letby was fundamentally flawed. New and extensive medical analysis by experts from across the globe has revealed that no evidence of deliberate harm to any of the infants involved exists and that the immunoassay results are unreliable. Her conviction is based on unsound evidence, and requires urgent review by the Court of Appeal.
Narrative B
Few investigations match the complexity and magnitude of the case against Lucy Letby. It involved two jury trials, two appeal court reviews, over 100 hours of jury deliberations, and an exhaustive six-year police investigation that compiled 32,000 pages of evidence. The fact is that the case against Letby was thoroughly and fairly examined.
