Former nurse Lucy Letby, already convicted of murdering seven babies and attempting to murder six others, has been found guilty of attempting to murder another newborn, known as Baby K, following a retrial. Letby, 34, was caught 'virtually red-handed' dislodging Baby K's breathing tube in February 2016 at the Countess of Chester Hospital. She has been sentenced to life imprisonment without the possibility of release. Baby K, born extremely premature, was transferred to another hospital and died three days later, though prosecutors do not attribute her death to Letby's actions. This new conviction solidifies Letby's status as Britain's most prolific serial child killer in recent history.
