In September 2022, before Letby's trial concluded, the RSS's Statistics and the Law Section published a general working-party report, 'Healthcare serial killer or coincidence?', chaired by Peter Green with contributions from Richard Gill and Jane Hutton. The Society wrote to the Thirlwall Inquiry in September and November 2023 recommending its terms of reference include the appropriate use of statistical monitoring data in neonatal settings.
In a July 2024 statement, the RSS said it was 'aware of concerns raised by some RSS members and the wider statistical community around the statistical aspects of the Lucy Letby case' and that its 2022 report 'highlighted the challenges of interpreting statistical evidence in medical murder cases'. It said it would convene a meeting on implementing the report's recommendations; it has not itself issued a finding on the safety of Letby's conviction.
