Nursing-staff perspective — what the colleagues actually said
Prosecution claim
The Crown's institutional narrative treated the nursing workforce on the Countess of Chester neonatal unit as a largely neutral background against which one nurse was identifiably anomalous.
Counter-evidence
Thirlwall Inquiry evidence from nursing colleagues — including ward manager Eirian Powell, senior nurses Kate Bissell and Yvonne Farmer, and others — tells a different story. Nurses on the unit describe a working environment under severe strain, with staffing levels, infant acuity, infrastructure failures, and infection-control pressures all beyond the unit's operational envelope. Several nurses specifically told the Inquiry that Letby was in their view a competent and caring colleague, and that the pattern the consultants were describing was not reflected in the nursing floor's day-to-day experience. This is not proof either way of the central criminal allegation — but it is evidence of the specific limited analytical base on which the 'common factor' reasoning was constructed, and it is evidence the jury was not systematically walked through.
You don't have one nurse behaving in a way her colleagues do not recognise in her. You have a unit in crisis in which one nurse works an unusual number of the crisis shifts.
What the jury heard
Selected nursing testimony was adduced at trial. The systematic Thirlwall Inquiry picture of nursing-workforce perspective on the unit had not yet been developed.
What the Panel says
The Panel does not opine on nursing-workforce perception directly but its finding of no medical evidence of deliberate harm is consistent with the nursing-floor picture of a unit in systemic strain rather than one with a deliberate harmer on it.
What independent experts add
- Ward Manager Eirian Powell's Thirlwall Inquiry evidence sets out the day-to-day operational picture of the unit in 2015–16.
- Nurse Kate Bissell and Nurse Yvonne Farmer gave evidence on workflow, handover practices and the collective nursing-staff perception of the consultants' concerns.
- Nurse Ashleigh Hudson gave evidence as a colleague on the unit during the cluster period.
- None of the nursing witnesses describes having observed Letby act in a way consistent with the Crown's later characterisation.
- The absence of a colleague who describes direct observation of suspicious behaviour is a significant evidential absence; in the Allitt case, by contrast, colleagues did give direct observational evidence.
