A 150-page dossier of 'never-before-seen' Lucy Letby documents could potentially prove the 'killer nurse' is actually innocent. The dossier, allegedly sent by a whistleblower, includes minutes from meetings involving police and hospital consultants, as well as email exchanges. It claims to have been sent from a source inside the Thirlwall Inquiry, which is exploring potential failures of staff and NHS systems. The results of the inquiry will be published later this year. Among those to receive the Letby dossier was Professor Richard Gill, who believes the dossier supports the idea of a 'witch hunt' and that 2026 could be a major year for Letby's case. He describes suspicions around Letby and looming fears of another NHS 'serial killer' as 'infecting' the investigation. Police became involved in the case despite an initial clinical probe highlighting systemic failures and staff shortages. The dossier supports the movement to get the Lucy Letby case properly reinvestigated. Letby was sentenced to 15 whole life orders after being convicted of murdering seven babies and attempting to murder seven more between June 2015 and June 2016 while working at The Countess of Chester Hospital. However, since her second trial concluded in July 2024, there have been growing concerns that she may be innocent. The charges Letby has been convicted of in full are listed, including the specific allegations and the verdicts. Letby's legal team has sent an appeal application to the Criminal Cases Review Commission, which reviews possible miscarriages of justice. Professor Gill believes the dossier will support the ongoing campaign to free Letby, if any of it can be proved as fresh evidence. He expects the CCRC to recommend the case is re-opened or express concerns, but the Court of Appeal may be cautious and come up with excuses. Cheshire Constabulary did not wish to comment when approached by The Sun.
