LONDON — Neonatal nurse Lucy Letby, who is the UK’s most prolific child serial killer in modern British history, will spend the rest of her life behind bars.

The 33-year-old was convicted of murdering seven babies and attempting to kill six other infants at the Countess of Chester Hospital.

Letby deliberately injected babies with air, force fed others milk and poisoned two of the infants with insulin. She refused to appear in the dock for her sentencing hearing.

Letby was given multiple whole-life sentences, one for each offense, becoming only the fourth woman in UK history to receive such a sentence.

Whole-life orders are the most severe punishment available and are reserved for those who commit the most heinous crimes.

Justice Goss said the “cruelty and calculation” of Letby’s actions between June 2015 and June 2016 were “truly horrific”.

“You acted in a way that was completely contrary to the normal human instincts of nurturing and caring for babies and in gross breach of the trust that all citizens place in those who work in the medical and caring professions,” he said.

He added handover sheets relating to all but the first four babies were found when police searched Letby’s home, which he was satisfied she kept as “morbid records”.

Sentencing her to a whole-life order for each offense, he said: “There was a malevolence bordering on sadism in your actions.

“During the course of this trial you have coldly denied any responsibility for your wrongdoing. You have no remorse. There are no mitigating factors.”

He said Letby, originally from Hereford, would be provided with copies of his remarks and the personal statements of the parents.

Ben Myers KC, defending Letby, said the neonatal nurse had “maintained her innocence throughout these proceedings” so there was nothing he was “able to add in mitigation that was capable of reducing the sentence”.

As the hearing began, there was silence, which hung heavy, as those in courtroom seven at Manchester Crown Court waited for the judge to enter the room.

The public gallery was full of the parents of the babies —some cried quietly as the victim impact statements were read earlier.

Their words made it clear the effect on their lives would be never-ending.

Some of the jury members, who sat through nine months of harrowing and complex evidence, were visibly upset as they heard about the grief, loss and distress suffered by each family.

Letby’s parents, who had been present throughout her trial, did not attend her sentence hearing.

The mother of a baby boy killed by Letby said she was “horrified that someone so evil exists” as the families’ victim impact statements were read out in court.

Addressing an empty dock, the mother of Baby C, who became emotional, told the court that knowing her son’s murderer was watching over them was like “something out of a horror story”.

The mother of Baby D, who was holding a toy rabbit as she read her statement, said Letby’s “wicked sense of entitlement and abuse of her role as a trusted nurse” was a “scandal”.

Baby E and F’s mother described Letby as a “coward” for failing to attend the sentencing hearing, adding: “Our world was shattered when we encountered evil disguised as a caring nurse.”

“We have attended court day in and day out, yet she decides she has had enough, and stays in her cell — just one final act of wickedness from a coward,” she said.

The parents of Baby G, who was the most premature of all the babies, weighing just 535g (1lb 3oz) and now requires constant care, told the court: “God saved her” but then “the devil found her”.

The parents of Baby N, who Letby attempted to murder in June 2016, said the family still had a camera in their now seven-year-old’s bedroom so they can check on him while he sleeps.

“We are extremely protective,” they said.

A total of 70 criminals are serving a whole-life order, four of whom are being held in secure hospitals.

They will never be considered for release, unless there are exceptional compassionate grounds to warrant it.

The other women to have been given a whole-life sentence are serial killers Rose West and Joanna Dennehy, as well as Moors murderer Myra Hindley, who died in 2002.

Sir Keir Starmer has urged the government to “get on” and bring forward proposals to force offenders to face their victims after Letby refused to appear in the dock.

“I want to see action as quickly as possible in this case, because victims’ families have been through the most awful ordeal,” he said.

“I hope the government will do it because I think it can be done very quickly.” — BBC
