Early Life and Medical Foundations
Education and Early Career Progression
Dewi Evans began his academic journey in Wales, attending Carmarthen Grammar School before studying medicine at Cardiff Medical School. He qualified in 1971 and swiftly advanced through various clinical disciplines, initially gaining additional credentials in obstetrics and gynaecology before focusing on paediatrics. His dedication to learning and specialization led him to earn fellowship titles from both the Royal College of Physicians and the Royal College of Paediatrics and Child Health.
Evans’ early roles in hospitals across South Wales gave him hands-on experience in a range of paediatric and neonatal care challenges. These formative years not only honed his clinical instincts but also laid the groundwork for what would become a career of medical and legal consequence.
Consultant Leadership and Healthcare Contributions
He served as a consultant paediatrician at major hospitals such as Morriston and Singleton in Swansea. His responsibilities went beyond treatment; he was instrumental in developing new maternity and neonatal care systems in the region. As a clinical director, he was known for his firm leadership and for implementing protocols that improved newborn survival and care standards.
Evans’ reputation within medical circles was shaped by both his technical knowledge and his willingness to challenge institutional inertia. His work wasn’t confined to hospital wards—he helped shape paediatric guidelines and spoke publicly on matters affecting child health policy in the UK.
Transition to Expert Witness: A Second Career
Founding a Consultancy in Paediatrics
After retiring from full-time clinical work in 2009, Dewi Evans founded Dewi Evans Paediatric Consulting Ltd, shifting his focus to legal and forensic review. His goal was to offer expert medical opinion in cases where children’s health or deaths required specialist scrutiny. These included clinical negligence claims, suspected child abuse, family court matters, and, most notably, criminal cases involving infant fatalities.
His expertise in interpreting complex medical records made him a sought-after figure in legal circles. Lawyers on both sides of the courtroom valued his ability to distill medical jargon into understandable, court-friendly explanations.
Key Cases and Legal Footprint
Evans worked on numerous legal cases over the years, but none matched the national significance of the Lucy Letby trial. Tasked with reviewing unexplained deaths and collapses of babies in a neonatal unit, Evans became the lead expert for the prosecution. His interpretation of clinical notes and postmortem findings became a cornerstone of the Crown’s argument that foul play was involved.
His testimony, while powerful, was not without criticism. Some experts and legal commentators questioned elements of his methodology, including instances where his medical opinions evolved over the course of the investigation. Still, the weight of his evidence was significant in helping the jury reach a verdict.
Strengths, Criticisms, and the Weight of Influence
Depth of Experience and Authority
Few experts bring as much clinical gravitas to court as Dewi Evans. His decades in neonatal and paediatric medicine are unmatched by many in his field. His commitment to thorough case review, cautious yet decisive language, and willingness to confront difficult truths have earned him recognition among colleagues and prosecutors.
His reports often seek to combine physiological explanation with pattern analysis, particularly in multi-case scenarios such as serial infant deaths. He has repeatedly stated that he serves the court—not the prosecution or defense—a guiding principle he believes ensures impartiality.
Controversies and Judicial Pushback
Evans’ credibility has been challenged in several legal contexts. In one case, a judge described one of his expert reports as “worthless,” citing a lack of balance. In others, defense teams have pointed out inconsistencies in his opinions over time or suggested that he sometimes overstepped his medical scope when drawing legal conclusions.
The Lucy Letby trial intensified this scrutiny. Some viewed his interpretations of air embolism and other causes of death as speculative, particularly given the complexity of neonatal care. Nonetheless, the presiding judge allowed his testimony, ruling that it was for the jury to determine its credibility.
A Legacy of Impact and Ethical Debate
Advancing Forensic Paediatrics
Evans has played a defining role in legitimizing paediatric forensic consulting as a vital legal tool. By applying medical expertise to court proceedings, he has helped clarify difficult cases that once seemed medically ambiguous. His work highlights the importance of experienced clinicians in ensuring justice in sensitive child-related matters.
His contribution has pushed both the legal and medical fields to ask harder questions: How much certainty is required for an expert opinion? Where does science end and speculation begin? And how do we balance the need for justice with the limits of current medical understanding?
Walking the Line Between Justice and Judgment
Dewi Evans embodies the tensions that come with bridging medicine and law. On one hand, he is celebrated for giving voice to children who cannot speak for themselves. On the other, he has faced criticism for potentially misinterpreting ambiguous signs in complex environments like neonatal units.
Regardless of where one stands on his conclusions, it’s clear that his work has sparked valuable discussion about the role of expert witnesses, especially in high-stakes cases involving life and death.

For some, Dewi Evans is a hero of justice; for others, a figure who illustrates the dangers of over-reliance on medical opinion in legal matters. What remains undeniable is his impact.
