The Thirlwall Inquiry, investigating the case of Lucy Letby who murdered seven infants, witnessed key testimonies from former hospital executives. They faced scrutiny over their handling of warnings about Letby and the ensuing lack of accountability. Despite acknowledging failures in communication with victims’ families, the directors, including Alison Kelly and Ian Harvey, were careful with their wording, emphasizing their intent while expressing regret. The inquiry seeks to determine what went wrong and whether corporate manslaughter charges could apply to the hospital trust.
