During the investigation into Lucy Letby, the nurse who was found guilty of killing seven babies in her care, police discovered disturbing "sympathy" cards that she had sent to the parents of her victims.
As previously reported, Letby, a 33-year-old British nurse, has been sentenced to spend the rest of her life behind bars for the shocking deaths of seven babies under her care.
The verdict was delivered after she was found guilty of both killing seven infants and attempting to murder six others while working in the neonatal unit of the Countess of Chester Hospital.
As per Sky News, the 33-year-old had written cards to the parents of her victims which expressed her sympathy, adding a new sinister layer to her crimes.

Letby had sent the card to the parents of Child I, who died in 2015. Taking an image of it shortly before the funeral, the card held messages of sympathy from the convicted murderer, where she expressed her sorrow for the loss, and touched on how it was a "privilege" to care for Child I.
Finishing the card, Letby wrote: "Thinking of you today and always - sorry I cannot be there to say goodbye. Lots of love, Lucy."
Alongside this discovery, the police also found what appeared to be post-it notes holding confessions, which demonstrated Letby's state of mind during the time of the murders.
On one note from 2016, police found that Letby had penned: "I AM EVIL I DID THIS," before adding: "I killed them on purpose because I'm not good enough."
Her defense barrister claimed that the notes were from a woman in anguish who was unable to do her job, though the prosecution pushed that they were notes of confession as opposed to a woman in distress.
The sentencing took place at Manchester Crown Court, where Letby did not make an appearance. She was handed a whole-life order, ensuring her confinement until her death, except under very exceptional circumstances.
Mr. Justice Goss, presiding over the case, revealed that Letby's actions were marked by "premeditation, calculation, and cunning." He painted a grim picture of the impact her crimes had on families, stating that "loving parents have been robbed of their cherished children," inflicting deep psychological trauma that will last a lifetime.
Letby appeared to seize moments when colleagues were on breaks to harm the vulnerable infants, exploiting the fact that a nurse would rarely be suspected of such malicious intent.
Mr. Justice Goss condemned Letby's behavior as a betrayal of the very principles that healthcare professionals uphold. He said: "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."
One mother, who identified her child as Child D, described the revelation that her baby had been murdered by a nurse in the hospital as "like something out of a horror story." She recounted that her baby's funeral was held just a day before the due date, and the infant's organs could not be donated due to the necessity of a post-mortem examination.
Letby's actions have marked her as the UK's most prolific child killer in modern history.
