Paediatric radiology expert for the prosecution
Gave post-mortem radiology evidence for the Crown.
Radiological findings were consistent with the prosecution's mechanisms (intravascular gas, air-in-stomach).
Independent paediatric radiologists have re-read the imaging and argue the findings are more consistent with NEC, sepsis and other natural causes than with the prosecution's deliberate-harm framing.

Trial prosecution experts.
Lead causation expert at trial
Main contribution: Provided the principal medical-causation narrative across the indictment, diagnosing air embolism, exogenous insulin and gastric-air administration as mechanisms of harm.
Key claim: Skin-discolouration patterns and gas findings were diagnostic of deliberate harm via intravenous air, insulin administration and air-in-stomach.
Criticism: Methodology rejected by the 14-member Shoo Lee International Expert Panel (Feb 2025). Lee himself states the prosecution misapplied his 1989 paper. A family court judge separately described an unrelated Evans expert report as 'worthless' (2023). Self-referred to Cheshire Police; out of routine NICU practice for over a decade at the time of trial.

Second-opinion neonatology expert at trial
Main contribution: Largely corroborated Dr Evans's conclusions at trial.
Key claim: Supported the air-embolism and insulin theories advanced by Dr Evans.
Criticism: Independent neonatologists argue her conclusions rest on the same methodology as Dr Evans's and inherit its limitations — same-methodology-second-clinician rather than independent corroboration.

Reviewing pathologist for the prosecution
Main contribution: Re-read original autopsy material on behalf of the Crown.
Key claim: Identified pathology findings the Crown argued were consistent with the deliberate-harm mechanisms.
Criticism: Independent paediatric-pathology re-readings filed October 2025 (supplementary CCRC submissions) argue the preserved post-mortem material is compatible with natural pathology.
