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.
The Crown alleged Child C, an extremely premature infant, deteriorated and died because Lucy Letby deliberately introduced air via a nasogastric tube. The prosecution treated the deterioration as anomalous and as requiring a deliberate-act explanation.
Child C's clinical record contains pre-existing infection findings consistent with pneumonia, against a background of antenatal reversed end-diastolic flow on Doppler ultrasound recorded approximately three weeks before delivery. Both findings substantially elevate the baseline collapse risk for any extremely premature infant. Independent paediatric review by Dr Martyn Pitman and others has emphasised that the antenatal severity and the documented infection together account for the deterioration without any deliberate act, but that the centrality of these natural-cause factors was not foregrounded for the jury when assessing the alleged criminal mechanism.
A baby with documented reversed end-diastolic flow in the weeks before delivery and pneumonia at the time of collapse carries a substantially elevated risk profile that alters the baseline against which any postnatal clinical event must be measured.
The Crown emphasised the alleged NG-tube air-injection mechanism and Letby's presence at the deterioration. The full antenatal trajectory and the pre-existing pneumonia were not given the prominence they would carry in a clinical-causation review.
The international Panel's case-by-case review identified natural-cause and prematurity-associated mechanisms fully consistent with the deterioration in Child C and inconsistent with the prosecution's deliberate-air mechanism on the physiological grounds set out in the Panel's NG-tube analysis.
