The clinical picture at birth
Child C was born at approximately 30 weeks’ gestation. 30-week infants are extremely preterm by any UK or international classification. Their survival-to-discharge rate is high with modern neonatal intensive care, but their risk profile during the neonatal period includes respiratory distress syndrome, necrotising enterocolitis, intraventricular haemorrhage, sepsis and feed intolerance — all at substantially elevated rates compared to term babies.
Child C’s antenatal record and admission clinical picture placed him in the high-acuity end of the preterm-infant population. The unit on which he was being cared for was a Level 2 NICU that was, in 2015, operating beyond its designed acuity range.
The prosecution theory
The Crown’s mechanism on Child C’s case was that Lucy Letby deliberately pushed air into the stomach via his NG tube, causing gastric distension, respiratory compromise and circulatory collapse. The theory relied on the general proposition that “air in stomach” at autopsy and X-ray was a signature of deliberate injection. It also relied on the shift-rota chart placing Letby at the collapse.
What the Panel reads from the same record
The Shoo Lee International Expert Panel’s case-by-case review (Feb 2025 and Additional 10 Cases Jun 2025) reads the Child C clinical record differently. The Panel’s position on this case can be reduced to four points:
- The antenatal and early-neonatal record documents identifiable natural pathology. A 30-week infant with the specific antenatal risk factors documented in the record is at the expected high end of collapse risk without any deliberate act being posited.
- The clinical trajectory is consistent with evolving natural pathology. Feed intolerance, abdominal signs, and respiratory deterioration in this sequence, in this patient, in this setting, match the presentation of evolving NEC or sepsis — both leading causes of death in preterm infants.
- The “air in stomach” finding is not diagnostic. Air in the stomach in a neonate with this clinical picture is a non-specific finding with many causes. It is not a specific signature of deliberate injection, as the NG-tube mechanism analysis (see our page on this) establishes.
- Unit context. The unit was, during the cluster period, operating under staffing and infrastructure strain. Sub-optimal clinical care under those conditions is a plausible contributing factor to deterioration of a high-risk preterm infant — and the Panel’s framework explicitly includes this as an alternative explanation.
Why this case is structurally important
Child C was one of the earliest indicted cases — death date 14 June 2015, only days after Child A’s death on 8 June. If the Crown’s narrative is right, Child C’s case is evidence of a pattern of deliberate harm beginning within a week of the alleged first event. If the Panel’s reading is right, Child C’s case is evidence that the pattern of deaths on the unit that summer was what it looked like on paper: a Level 2 unit with a cluster of extremely preterm infants with serious underlying pathology, insufficient staffing, and infection-control problems.
Because Child C’s case comes so early, how the evidence reads on this one baby is effectively how the overall pattern of 2015 is read. That is why the Panel’s re-reading of this specific case matters for the convictions as a whole.
What a modern differential-diagnosis review looks like
A modern UK NICU mortality-and-morbidity review of Child C’s case would, applying current methodology, systematically consider:
- Evolving necrotising enterocolitis.
- Late-onset neonatal sepsis (bacterial, including the outbreak pathogen).
- Intraventricular haemorrhage with secondary deterioration.
- Ventilator-associated complications.
- Metabolic decompensation.
- The rare: air embolism from central venous access.
- The very rare: deliberate intervention.
The trial process ran the list in the reverse direction, starting from the rare end. The Panel’s review corrects the methodology.
