The mother of a baby murdered by Lucy Letby, known as Baby D, shares her harrowing experience in a new Netflix documentary. She reflects on the years since her daughter's death, feeling a sense of failure as a mother for not being able to protect her. The documentary, titled 'The Investigation of Lucy Letby', delves into the tragic story of Baby D, who died in 2015 after being injected with air by Letby, a neonatal nurse. Letby was convicted of murdering seven babies and attempting to murder seven others at the Countess of Chester hospital between 2015 and 2016, serving 15 whole life sentences. The baby's mother, using the pseudonym 'Sarah', describes the emotional toll of the trial, sitting just three meters away from Letby, who stared at her repeatedly. Despite the overwhelming evidence, Letby's defense team argues for her innocence, with her barrister, Mark MacDonald, emphasizing the lack of direct evidence and motive. An international panel of medical experts, led by Dr. Shoo Lee, also questioned the convictions, suggesting alternative explanations for the deaths. However, the consultants who raised initial concerns have faced backlash and accusations of lying to cover up their own failings. The case remains under scrutiny, with a government inquiry pending and the Criminal Cases Review Commission reviewing the evidence, as the parents of the victims strive to cope with the ongoing revelations.
