In early 2025, the findings of an international panel of medical experts working for Letby’s defence team were revealed at a press conference.
They concluded there were alternative explanations for each of Letby’s convictions.
The panel was led by a Canadian neonatal expert, Dr Shoo Lee, who told the assembled media: “We did not find any murders. In all cases, death or injury were due to natural causes or just bad medical care.”
Lee became involved after realising that a medical paper he had co-authored in 1989 had been used in the prosecution’s case. He said it had been misinterpreted.
Interviewed for the documentary, he said: “A young woman could be in jail for crimes that she did not commit.”
The panel’s findings, which have been submitted to the Criminal Cases Review Commission (CCRC) as part of an application made by Letby’s lawyers for her case to be investigated as a potential miscarriage of justice, have been rejected by Gibbs.
“We were understaffed – that’s generally true in most departments on most wards on the NHS,” he said. “But we had had those same staffing pressures before 2015 and 2016 and we’d not had those increased deaths then.”
He said the consultants had been targeted online by amateur sleuths convinced of Letby’s innocence.
Gibbs said they accused the consultants of lying to cover up their own failings.
Gibbs said: “Where’s your evidence of that?
“Blaming a colleague – which is a dreadful thing to do – for possibly murdering and attempting to murder babies is the worst way in the world to try and cover up problems and inadequacies on the neonatal unit.”
But he added: “I live with two guilts. Guilt that we let the babies down.
“And tiny, tiny, tiny guilt – did we get the wrong person? Just in case – miscarriage of justice?”
“I don’t think there was a miscarriage of justice but you worry that no-one actually saw her do it.”
