A TOP doctor whose work was used to convict killer nurse Lucy Letby has revealed why he "knows" she's innocent. Letby is serving 15 whole-life sentences for the murders of seven babies and the attempted murders of seven others in her care at the Countess of Chester Hospital. During her trial, an academic paper by Dr Shoo Lee, one of Canada's top neonatologists, was used to support the theory that she killed some of the infants by injecting them with air.

But according to the doctor, his paper was "misrepresented". Despite enjoying a peaceful retirement on his farm in Canada, he decided to testify for Letby at her appeal in October 2023 - which subsequently failed. In an exclusive interview with The Sun - after launching a renewed bid to challenge her conviction - Dr Lee has now revealed why he came out of retirement to try to clear Letby's name. He said: "Sometimes in life we need people to stand up for us and if we don't do that then we're a bit short on humanity.".

According to the neonatologist, the killer nurse's life-sentence is based on "wrong evidence". He continued: "I can say she is innocent. Our conclusion was that there was no murder. "If there's no murderer, then I don't know what she's doing in prison.". But despite the support of Dr Lee and others like him, there are still many who believe and support the court's guilty verdicts. Letby's trial judge said she showed “deep malevolence bordering on sadism” after she was convicted of preying on babies small enough to fit in the palm of her hand.

Seven consultants who had worked alongside Letby — with more than 100 years experience between them — are also convinced she was deliberately harming newborns. And the Criminal Cases Review Commission (CCRC) this week urged people to “remember the families” of the victims amid the storm of “speculation…from parties with only a partial view of the evidence”. But Dr Lee is insistent, adding: "If the prosecution had properly interpreted my paper, she wouldn't have been convicted in the first place.".

Letby's failed appeal left him utterly "disturbed" knowing this meant she would spend the rest of her life behind bars, he said. Dr Lee added: "It didn't seem right because someone has just been convicted using wrong evidence.". He added: "Perhaps the clever thing to do would be to do nothing and say, that's none of my business. "It's not even my country for heaven's sake. But it just didn't feel right.

"I thought if the evidence being used was wrong then this would be a real miscarriage of justice.". Following two of the nurse's failed efforts to overturn her convictions, he assembled 14 experts from around the world to analyse the medical evidence against her. Their report, which was revealed at a press conference on Tuesday, and will now be considered by the CRCC, said there were "no murders". For their part, families of Letby's victims reacted with fury, with the mum of one baby boy who she tried to murder blasting Dr Lee's intervention as a "publicity stunt".

But, talking after the event, Dr Lee told The Sun that staff shortages and lack of medical knowledge played a key role in the babies' deaths. I can say she is innocent. Our conclusion was that there was no murder. "If the medical care had been better, perhaps some of the babies may have survived," he said. As for Letby, he claims she had no involvement in the infants' deaths at all. Instead, he believes the blame is more likely to land on senior members of NHS staff if a fresh investigation is launched.

He said: "As far as Lucy is concerned, I don't know of anything I could see in the medical records that would suggest she was part of the poor care that was provided. "I suspect that some of the doctors will be at the receiving end of some of these [lawsuits]. "I didn't see anything that would suggest that Lucy would be involved with that.". May 18, 2017: Cheshire Police launch an investigation following reports of a greater number of baby death at the hospital between June 2015 and June 2016.
