A panel of international medical experts has given alternative causes of death in several cases against Lucy Letby.
Retired neonatologist Dr Shoo Lee, who co-authored an academic paper on air embolisms (bubbles) in babies in 1989 which featured prominently in the trial, chaired a panel of 14 experts to compile an “impartial evidence-based report”.
Dr Lee said he believed his findings on skin mottling were misinterpreted by the prosecution. He said in a new paper he published in December 2024 there were no cases of skin discolouration when air was injected into the veins.
At her trial in 2023, prosecutors pointed to skin discolouration in several of the victims as evidence that air had been injected into their veins by Letby.
“The notion that these cases are air embolism because they collapsed and because there were skin rashes has no basis in evidence. Let’s be clear about that,” Dr Lee said.

The panel laid out alternative causes of death in many of the cases, including natural causes and poor medical care at Countess of Chester Hospital.
“We did not find any murders,” Dr Lee said. “In all cases, death or injury were due to natural causes or just bad medical care.”
Asked about the Countess of Chester Hospital, Dr Lee, a retired medic from Canada, said: “I would say if this was a hospital in Canada, it would be shut down. It would not be happening.”
Sky News has approached the Countess of Chester Hospital for comment.
Minutes before the conference began, the Criminal Cases Review Commission, which investigates potential miscarriages of justice, announced it would review Letby’s case after receiving an application from her lawyers on Monday.
Opening the press conference, MP Sir David Davis described Letby’s convictions as “one of the major injustices of modern times”.
Findings will be earth-shattering for babies’ parents
This must have been one of the most distressing mornings for the grieving parents of the babies who died in Chester.
A 10-month trial concluded their new borns were murdered by Lucy Letby.
Now they have been presented with a body of evidence gathered by some of the world’s leading neonatal experts that could and probably will put some doubt against her conviction.
Every single baby’s death has been forensically analysed: the allegations presented in court with the circumstances of each death against what the panel claims are the clinical facts in the case.
Dr Shoo Lee, the panel chair, approached Letby’s lawyers following her conviction in 2023. He was convinced his 1989 paper on neonatal deaths used as evidence in the case against Letby had been misinterpreted.
The team he has assembled to examine each death is a world leader in their own respective field.
For parents learning today these experts believe some of the baby deaths were preventable and not the result of a serial killer nurse will come as nothing less than earth-shattering.
This expert panel review of each case, if true, could point to yet another systemic failure of NHS maternity care.
But now it will be for the Criminal Cases Review Commission to decide if Letby’s case is investigated as a potential miscarriage of justice.
Letby, 35, the UK’s most prolific child killer of modern times, is serving fifteen whole life terms in prison after she was convicted at Manchester Crown Court of murdering seven infants and attempting to murder seven others between June 2015 and June 2016.
Various methods were used to attack the babies while the defendant worked as a nurse on the neonatal unit at the Countess of Chester Hospital.
One method was air being injected into the bloodstream which caused an air embolism, blocking the bloody supply and leading to sudden and unexpected collapses.
Last year Letby lost two bids 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.
In December, the former nurse’s barrister, Mark McDonald, said he would seek permission from the Court of Appeal to re-open her case on the grounds Dr Dewi Evans, the lead prosecution medical expert at her trial, was “not reliable”.
Dr Evans, a retired consultant paediatrician, said concerns regarding his evidence were “unsubstantiated, unfounded, inaccurate”.
In September a public inquiry into how Letby was able to commit her crimes began hearing evidence. Closing legal submissions are expected in March and the findings are expected to be published this autumn.
Detectives from Cheshire Constabulary are also continuing their review of the care of some 4,000 babies admitted to the Countess of Chester Hospital from January 2012 to the end of June 2016, while Letby worked as a neonatal nurse, there. It also includes two work placements at Liverpool Women’s Hospital in 2012 and 2015.
Letby has been interviewed under caution at HMP Bronzefield in Ashford, Surrey, in relation to the ongoing investigation into baby deaths and non-fatal collapses.
The family of a nine-year-old girl stabbed to death have said she was a “beautiful soul” who was brave, kind-hearted and “always put a smile on people’s faces”.
Police were called to Lime Close in Weston-super-Mare, Somerset, just before 6.10pm on Monday, where Aria Thorpe had suffered a single stab wound.
The child was pronounced dead at the scene.
In a tribute released by Avon and Somerset Police on Friday, the girl’s family on her mother’s side said: “For those who didn’t have the privilege of knowing Aria, she was the most beautiful little soul – happy-go-lucky, full of light, and joy.
“She loved to sing and dance, and she took such pride in dressing up, always wanting to look just like her mummy.”
Tom Thorpe, the girl’s father, said: “It’s hard to put into words how devastating it is, our little Aria, that you’re up there with the angels looking over us.”
It comes as a 15-year-old boy charged with Aria’s murder appeared in court.

Aria was a ‘precious girl’
In their statement, Aria’s family on her mother’s side said her death “has devastated us beyond words”.
“Our hearts are broken in a way we never imagined possible,” they added.
“As a family, we are holding one another close and doing everything we can to support each other through this unimaginable time.”
They said they were “truly touched by the lovely messages we have received”, before asking “that our privacy is respected, as we try to come to terms with the terrible loss of our precious girl”.

‘Wacky ways and outright madness’
Mr Thorpe said: “How sad it’s going to be not hearing ‘Dad, how long left?’ on our long journeys back and forth at weekends.
He then said that Aria was “such a brave, kind-hearted and a beautiful innocent soul”, and “always put a smile on people’s faces with your wacky ways and just outright madness”.
Mr Thorpe added: “Your other little family down here in Portsmouth will forever miss you.
“We’ll miss you begging to go outside, even in the pouring rain just to have as much fun as possible in the little time we had at weekends.
“You will be greatly missed, you special little angel. A life gone far too early but I hope a life lived well. We all love you dearly. Goodnight darling.”
Teenager in court
Meanwhile, a 15-year-old boy charged with Aria’s murder appeared at Bristol Crown Court on Friday, where he was remanded.
The teenager, who cannot be named because of his age, was arrested in the Somerset village of Worle at 6.19pm on Monday.
He is next due in court on 16 March 2026. Appearing via video link from youth detention accommodation, he spoke only to confirm his name.
Judge Peter Blair KC set a provisional trial date for 15 June during the hearing.
David Walliams has been dropped by his publisher HarperCollins UK.
A spokesperson for the company said that “after careful consideration, and under the leadership of its new CEO, HarperCollins UK has decided not to publish any new titles” from Walliams.
“HarperCollins takes employee well-being extremely seriously and has processes in place for reporting and investigating concerns,” the spokesperson added.
“To respect the privacy of individuals, we do not comment on internal matters.”
The publisher announced in October that it had appointed Kate Elton as its new chief executive, following the departure of former boss Charlie Redmayne.
The 54-year-old, who shot to fame with the BBC sketch show Little Britain, is one of the country’s best-selling children’s authors.
He has written more than 40 books, which have sold more than 60 million copies worldwide and been translated into 55 languages, according to his website.
His first children’s book, The Boy in the Dress, was published by HarperCollins in 2008.
Walliams is also known for Come Fly With Me, another BBC sketch show, and was formerly part of the judging panel for Britain’s Got Talent.
He was awarded an OBE in 2017 for services to charity and the arts.
Walliams has been contacted for comment.
