Is Lucy Letby Innocent? Dr Svilena Dimitrova Explains the Evidence | Part 2

In the second and final part of this special two-part series, True Criminals continues its examination of the case of Lucy Letby — the neonatal nurse convicted at Manchester Crown Court of murdering seven babies and attempting to murder seven others at the Countess of Chester Hospital. Letby is currently serving multiple whole life orders, following convictions secured after a lengthy investigation by Cheshire Police known as Operation Hummingbird. At trial, the prosecution argued that babies were deliberately harmed through methods including air embolism, insulin administration and physical interference. But the case has since become the subject of intense debate among some medical experts, legal commentators and campaigners who question whether the convictions are safe. In this episode, Sky News crime correspondent Martin Brunt and journalist Helen Fospero explore the ongoing arguments surrounding the evidence presented to the jury — including the medical testimony, statistical analysis and clinical interpretations that played a central role in the prosecution case. Our guest once again is consultant neonatologist Dr Svilena Dimitrova, who has reviewed large parts of the medical evidence used during the trial. She discusses why she believes some of the conclusions presented in court are deeply flawed, raising questions about issues including the interpretation of insulin test results, the statistical chart used to link Letby to baby collapses, and the clinical understanding of events inside the neonatal unit. Dr Dimitrova also addresses the controversial question of whether systemic failures within the hospital — including staffing pressures, clinical oversight and wider NHS challenges — may provide alternative explanations for some of the tragedies that occurred on the unit in 2015 and 2016. The episode examines why the defence at trial called no expert medical witnesses, the role played by prosecution expert testimony, and the debate now unfolding among specialists about how complex neonatal medicine was presented to a jury. We also explore what could happen next in the legal process. Letby’s legal team has asked the Criminal Cases Review Commission (CCRC) to examine the case, a step that could potentially lead to the Court of Appeal reviewing the convictions if the commission finds grounds that they may be unsafe. At the centre of this story remain the babies who died or collapsed and the families who continue to live with the consequences of those events. Their loss is profound and enduring. This podcast examines the evidence and the arguments with care, recognising the complexity and sensitivity of a case that continues to divide opinion across the UK. ....................................
