Lucy Letby was found guilty of murdering seven babies and attempting to murder six other infants while working on a hospital's neonatal unit between June 2015 and June 2016. Among the guilty verdicts, Letby was convicted of 2 counts of attempted murder involving the same infant. She was also found not guilty of two charges of attempted murder. The jury was unable to reach verdicts on six further counts of attempted murder. Two of her victims, known as Child L and M, were twin brothers. They had been born prematurely and were just days old when Letby tried to kill them within hours of each other, in April 2016. Both Child M and Child L, who Letby tried to poison with insulin, survived the assaults. However, Child M has been left with brain damage. Two of her last victims were boys, known as Children O and P, who were two of three triplet siblings. Both died within the first week of their lives, and Child O was found with severe liver damage. The jury heard the nurse would misuse medical equipment and medicines to cause babies to unexpectedly collapse across day and night shifts on the hospital's neonatal ward.
