Lucy Letby's handwritten confession about her 'evil' leaves experts baffled over her motive for becoming Britain's most prolific child murderer... but investigator claims it does provides an explanation

 

 

 

 Nobody but Lucy Letby (left) knows what drove her to kill and attack premature babies in her care. Police found nothing in her background or upbringing, or any event that may have triggered her killing spree which began in June 2015. Evidence that she became animated and excited after the babies' deaths, enjoyed the drama of the emergencies when infants collapsed and was quick to tell her colleagues in texts when something unusual and tragic had happened on her shift, pointed to her revelling in the attention, they said. Letby was psychologically assessed and deemed fit to stand trial, but this desire to be at the centre of a crisis could be a symptom of the mental disorder Munchausen's syndrome, one leading criminologist told the Mail.
