Fourteen experts worldwide are preparing to present what they describe as 'significant new medical evidence' regarding the Lucy Letby case. The 35-year-old former neonatal nurse is currently serving 15 whole-life orders after being convicted at Manchester Crown Court of murdering seven infants and attempting to murder seven others.

The case has faced intense scrutiny over the past year. Letby, who maintains her innocence, has had two attempts to appeal her convictions denied.

An international panel of experts in neonatal care is scheduled to present their analysis at a press conference in London later today, February 4. Notable among them is retired medic Dr Shoo Lee, co-author of a significant 1989 paper on air embolism in babies, which played a key role in Letby’s 10-month trial.

Evidence presented in court revealed how Letby, from Hereford, harmed infants on the neonatal unit at the Countess of Chester Hospital through various methods between June 2015 and June 2016. One method involved injecting air into the bloodstream, which caused air embolisms that led to sudden and unexpected collapses in the infants.

Dr Lee has indicated that his findings regarding skin discolouration were misinterpreted by the prosecution. Reports suggest the expert panel discovered alternative causes of death for a 'large number' of the babies involved in the trial.

Letby’s lawyers are planning to apply to the independent Criminal Cases Review Commission (CCRC), which investigates potential miscarriages of justice and can refer cases back to the Court of Appeal. Tory former minister Sir David Davis, who recently raised concerns on behalf of Letby’s legal team in the House of Commons, will chair the panel. Her barrister, Mark McDonald, will also attend.

Sir David, MP for Goole and Pocklington, advocates for a retrial for Letby, stating he believes it will exonerate her. In 2022, Letby lost two appeals: one in May concerning seven murders and seven attempted murders and another in October regarding the attempted murder of a baby girl, which was determined by a different jury at a retrial.

During her first appeal, an attempt to introduce new evidence from Dr Lee was rejected, as three senior judges concluded there was no prosecution expert evidence diagnosing air embolism solely based on skin discolouration. Dr Lee has since updated his academic paper and asserts he found no cases of skin discolouration linked to air embolism via the venous system.

In December, Mr McDonald announced plans to request the Court of Appeal's permission to reopen Letby’s case, arguing that lead prosecution expert Dr Dewi Evans was 'not reliable'. Dr Evans has responded that concerns regarding his evidence were 'unsubstantiated, unfounded, inaccurate'.

A public inquiry into how Letby managed to commit these crimes began hearing evidence in September, with closing legal submissions expected in March. The findings from Lady Justice Thirlwall are anticipated to be published this autumn.

Cheshire Constabulary detectives continue to review the care of approximately 4,000 babies admitted to the hospital during Letby’s tenure as a neonatal nurse, covering her work from January 2012 to June 2016, including placements at Liverpool Women’s Hospital in 2012 and 2015.

Letby has been interviewed at HMP Bronzefield in Ashford, Surrey, under caution regarding the ongoing investigation into baby deaths and non-fatal collapses, and she maintains her innocence.
