Lucy Letby cried from the dock “I’m innocent” after she was sentenced to a whole-life order for attempting to kill a newborn girl in what the judge called a “shocking act of calculated, callous cruelty”. The former neonatal nurse made the remark as she was taken to the court cells after being sentenced. The judge, James Goss KC, told the prison officers to take the defendant down when she turned to face him, turned out her palms and said “I’m innocent”, to gasps in the courtroom. Members of her newborn victim’s family – who had moments earlier described the everlasting grief of her crimes – appeared visibly shocked and emotional at Letby’s outburst. Letby, 34, was found guilty on Tuesday of trying to kill the extremely premature infant less than two hours after she was born on 17 February 2016. Letby was handed a 15th whole-life order, having been jailed last year for murdering seven babies and attempting to kill another six. Letby was convicted of attempting to kill a seventh infant, known as Baby K, after a three-week retrial at Manchester crown court. Goss told Letby she had deliberately interfered with the breathing tube of the tiny newborn – who was born 15 weeks’ premature and weighted only 692g (1.52lbs) – when a nurse had briefly left the infant’s side. Her actions were “completely contrary to the normal human instincts and nurturing and caring for babies”, he said, and were “in gross beach of the trust that all citizens place in those who work in the medical and caring professions”. Baby K died three days later after being transferred to a separate hospital. Letby was not accused of causing her death. Sentencing Letby, Goss said she could not be blamed for causing Baby K’s death but she was guilty of a “shocking act of calculated, callous cruelty”. As Letby stared straight ahead, Goss told her she was a “conscientious, hard-working, confident and professional nurse … which allowed you to harm babies without suspicion”. “Only you know the reason, or reasons, for your murderous campaign,” he said, adding that the impact of her crimes was “immense”. “You have no remorse. There are no mitigating factors,” he added. Eight members of the jury were in court to watch the sentencing. Fighting back tears, Baby K’s mother told a silent courtroom how she and her husband had been “beyond ecstatic and overwhelmed with love” when they heard their unborn child’s heartbeat for the first time, after a previous miscarriage. She described how their loss had affected every area of their lives, damaging their relationships, friendships and careers. “The impact is across all aspects of your life,” she said, “like ripples in the water, layer by layer of your life is touched”. As relatives became emotional in the public gallery, Baby K’s mother said the “biggest future struggle that plagues us each day” was how to tell their children about her death. “The devastation expands so far and for so long when a child is lost let alone under these circumstances,” she said. “Will we get answers and the verdict that we want? Will that actually bring some peace and closure?” Addressing Letby from the witness box, Baby K’s mother said her daughter was “not here, never will be, we will never have what would give us peace, closure, or a feeling of being complete family unit”. She went on: “However, you, Lucy Letby, will never hurt another child or have the privilege and joy that children give. “Our time and effort that you have absorbed over the years will stop today and our focus will remain on our beautiful children and building the most exciting and love-filled life that we possibly can.” Benjamin Myers KC, for Letby, said his client “recognised the sympathy” for the families but that she maintained her innocence. He said there was no mitigation. “The sentence is inevitable and there is no more I can say,” he said.
