The public inquiry into Lucy Letby's murders at the Countess of Chester Hospital has revealed significant details about the hospital's delayed response to the spike in neonatal deaths. Despite concerns from consultant paediatricians, Letby, known as 'nurse death,' was not removed from clinical duties until after several fatalities. The inquiry, led by Lady Justice Thirlwall, aims to understand how Letby was able to commit these crimes and scrutinize the hospital's internal governance and staff conduct. Comparisons have been drawn to previous cases like Beverley Allitt's, with a focus on lessons unlearned. The inquiry also addresses the distress caused by post-trial speculation and criticisms of the defense, emphasizing the need for closure for the victims' families.
