LUCY LETBY: 3 YEARS AFTER HER CONVICTION, HER CASE IS STILL FAR FROM OVER

Three years after Lucy Letby was convicted in one of Britain’s most closely watched criminal cases, the former neonatal nurse remains behind bars — while a new legal review continues to examine whether her convictions should be reconsidered.

Letby was convicted in 2023 of murdering seven babies and attempting to murder six others at the Countess of Chester Hospital between 2015 and 2016. After a 2024 retrial on another attempted-murder charge, she received a 15th whole-life sentence.

WHERE IS LUCY LETBY NOW?

Letby remains imprisoned at HMP Low Newton in County Durham, England, serving whole-life sentences.

Her convictions have not been overturned, and she remains legally convicted of the offenses for which she was sentenced.

But her legal team has continued fighting.

A NEW REVIEW COULD BECOME CRUCIAL

In February 2025, Letby’s defense submitted an application to the Criminal Cases Review Commission (CCRC), arguing that new medical evidence raises serious questions about the original convictions.

The CCRC has confirmed that its review of Letby’s convictions is underway.

The commission has also made clear that it does not decide whether Letby is innocent or guilty. Its role is to determine whether there is a possibility of a miscarriage of justice serious enough to justify referring the case back to an appeal court.

That distinction is important.

A CCRC investigation is not an acquittal, and it does not mean the convictions have been declared unsafe.

 WHY HAS THE EVIDENCE BECOME SO CONTROVERSIAL?

Letby’s defense has presented medical experts who dispute important elements of the prosecution’s case.

Those experts have argued that some of the babies’ collapses and deaths could potentially have resulted from natural medical conditions or problems with clinical care rather than deliberate harm.

The debate has become particularly intense around the interpretation of medical evidence involving insulin poisoning, air embolism and the babies’ underlying conditions.

At the same time, prosecution experts continue to stand by the conclusions presented during the original trials.

So far, no appeal court has overturned Letby’s convictions.

ANOTHER MAJOR DEVELOPMENT

The wider investigation into the Countess of Chester Hospital has also continued.

In 2025, three former senior hospital staff members were arrested on suspicion of gross negligence manslaughter as part of the investigation into the deaths and collapses of babies at the hospital.

However, those developments do not mean Letby’s convictions have been overturned or that the alternative explanations advanced by her defense have been legally established.

 NO MORE CHARGES AGAINST LETBY — FOR NOW

There was another important development in January 2026.

After reviewing evidence relating to nine additional infant cases, prosecutors decided not to bring further charges against Letby.

That decision concerns separate cases investigated after her original convictions. It does not change the existing convictions for which she is currently serving her sentences.

 WHY THE CASE IS BACK IN THE SPOTLIGHT

The case received another wave of international attention following Netflix’s 2026 documentary “The Investigation of Lucy Letby.”

The documentary revisited the original investigation and trial while featuring people who continue to question aspects of the evidence.

That has reignited a fierce public debate:

Was the evidence strong enough to establish deliberate harm beyond reasonable doubt — or could some of the medical events have been interpreted incorrectly?

Those questions remain contested.

 ONE OF BRITAIN’S MOST CONTROVERSIAL CASES

The controversy has become even more complicated because questions have been raised about some expert evidence used during the original trial.

For example, The Guardian reported in March 2026 that prosecution expert Professor Peter Hindmarsh had been under a professional investigation concerning his medical work when he gave evidence at Letby’s trial. Police and prosecutors said they had not been informed of that investigation before he testified.

That development has become part of the wider debate surrounding the reliability and presentation of expert evidence.

But again, it does not by itself overturn Letby’s convictions.

 WHAT HAPPENS NEXT?

For now, Lucy Letby remains in prison.

Her previous appeal attempt was rejected by the Court of Appeal in 2024.

Her convictions remain legally valid.

But the CCRC is now examining the new material submitted by her defense.

If the commission eventually finds a sufficient possibility that the convictions cannot safely stand, it could refer the case back to the Court of Appeal.

If it does not, the convictions remain in place.

 THREE YEARS AFTER THE VERDICT, THE BIG QUESTION HAS CHANGED.

The question is no longer simply “Where is Lucy Letby?”

It is:

COULD THE NEW EVIDENCE FORCE BRITAIN’S COURTS TO REEXAMINE ONE OF THE MOST CONTROVERSIAL CRIMINAL CASES OF THE DECADE?

For now, that answer remains unknown.

Lucy Letby remains imprisoned — while the legal battle surrounding her convictions continues.
