Just over nine months ago, the trial of a neonatal nurse accused of the most heinous crimes began.

This afternoon, the nation was rocked as 33-year-old Lucy Letby was found guilty of murdering seven innocent babies and attempting to take the lives of six more.

The story of how the church-going nurse became the most prolific child killer in modern British history has now been unveiled in a documentary by the Mail.
