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.
Baby O's haemorrhagic deterioration and death were caused by a deliberate act of harm by Lucy Letby, consistent with the Crown's theory of NG-tube-mediated air introduction or direct vascular harm, as part of the alleged pattern of acts on the unit.
The clinical record of Baby O's resuscitation documents a specific iatrogenic event that the prosecution did not foreground in its causation case. During Baby O's resuscitation, a consultant inserted a paracentesis cannula into a location that paediatric resuscitation guidance identifies as a high-risk anatomical zone. A paracentesis procedure — drainage of fluid from the abdominal cavity — performed in a haemodynamically compromised neonate, in a location outside the recommended insertion zone, creates a direct risk of vascular injury and haemorrhage. The Pitman case-by-case analysis and primary-record review identify this specific procedural event as a plausible primary cause of the haemorrhagic event subsequently attributed by the prosecution to Letby's alleged action. This is not a theoretical alternative — it is a specific documented event in Baby O's clinical record.
The paracentesis cannula insertion documented in Baby O's clinical record occurred in a location that paediatric resuscitation guidance identifies as high-risk for vascular injury. That documented iatrogenic event is a specific alternative explanation for the haemorrhage attributed to deliberate harm.
The jury heard the prosecution's mechanism theory for Baby O's death within the triplet-set narrative. The paracentesis cannula event — its anatomical location, its relationship to paediatric resuscitation guidance on safe insertion zones, and its potential contribution to the haemorrhagic outcome — was not foregrounded as a causation alternative in the prosecution's case.
The Panel's triplet-set review concludes that Baby O's death is explicable by natural causes and resuscitation-associated events without requiring a deliberate-harm explanation. The Panel's case-by-case analysis for Baby O specifically identifies iatrogenic contributors to the clinical course as live and unaddressed alternatives to the prosecution mechanism.
