Lawyers for child serial killer Lucy Letby will make a fresh bid to challenge her convictions on the grounds that the lead prosecution medical expert at her trial was “not reliable”.
Her barrister, Mark McDonald, said he would immediately seek permission from the Court of Appeal to take the “exceptional, but necessary, decision” to apply to reopen her case.
Speaking at a press conference at London’s Royal Society of Medicine, Mr McDonald said that “remarkably” Dr Dewi Evans had changed his mind over the mechanism of death involving three of Letby’s murder victims.
He said: “The defence will argue that Dr Evans is not a reliable expert, and all the convictions are not safe.”
Barrister Mark McDonald who is representing Lucy Letby
Letby, 34, from Hereford, is serving 15 whole-life orders after she was convicted at Manchester Crown Court of murdering seven infants and attempting to murder seven others, with two attempts on one of her victims, between June 2015 and June 2016.
She has lost two bids this year to challenge her convictions at the Court of Appeal – in May for seven murders and seven attempted murders and in October for the attempted murder of a baby girl which she was convicted of by a different jury at a retrial.
The Thirlwall Inquiry into how Letby was able to commit her crimes has heard evidence at Liverpool Town Hall since September and will resume in January, with findings expected to be published in autumn 2025.
