May 2026: Thirlwall Inquiry report delayed to at least September 2026 · six-baby inquests relisted to 2027 · CCRC review active · Shoo Lee Panel: no medical evidence of deliberate harm.
All the evidence. All the failings. All in one place.
The complete public-interest index: every key document, every institutional failing, every expert challenge to the prosecution case — drawn from the Thirlwall Inquiry, the February 2025 International Expert Panel, and the ongoing CCRC review.
Between 2015 and 2016, seventeen babies either died or suffered serious collapses on the neonatal unit at the Countess of Chester Hospital. Lucy Letby was convicted of seven murders and seven attempted murders in 2023 and a further count in 2024. In February 2025, fourteen international neonatologists led by Dr Shoo Lee publicly concluded that they found no medical evidence of deliberate harm in any of the cases reviewed. The case is now under review by the Criminal Cases Review Commission.
Case status
Key live disputes: medical causation (air embolism, insulin, NEC, sepsis); statistical reasoning (shift-chart, base rates, selection bias); documentary evidence (Post-it notes, Facebook searches, handover sheets); expert methodology and disclosure (Hindmarsh GMC non-disclosure; Evans methodology); door-swipe data mislabelling (CPS admission August 2024); hospital staffing, acuity and governance failings.
February 2025 — International Expert Panel
Convened by Dr Shoo Lee — Professor Emeritus of Paediatrics at the University of Toronto and the lead author of the 1989 air-embolism paper cited by the prosecution — the panel reviewed the medical evidence for every count on the indictment.
"There was no medical evidence to support malfeasance causing death or injury in any of the 17 cases in the trial."
— Dr Shoo Lee, speaking at the London press conference, Reported findings: 3 February 2025.
