What is the Lucy Letby documentary about?

The Investigation of Lucy Letby is a 90-minute documentary that focusses on the investigation into the neonatal nurse’s crimes, and the trial that followed, featuring interviews with the police, lawyers on both sides of the case, and the mother of one of the victims.

Letby was found guilty of murdering seven babies and attempting to murder seven more under her care at the Countess of Chester Hospital between June 2015 and June 2016. The crimes make her the UK’s most prolific child killer.

The Investigation of Lucy Letby is directed by Dominic Sivyer, with Netflix describing the film as follows:

“The feature length documentary includes, for the first time, new materials and testimony from the British police who investigated the case and never-before-seen footage of Letby during her arrest and questioning.

“The documentary also includes contributions from the mother of one of the victims speaking about her experiences and involvement in Letby’s trial. This is the first time that a family member involved in the prosecution has spoken in a documentary.

“The film includes interviews with experts and lawyers on both sides, giving the most comprehensive look at one of Britain’s most notorious crimes.”
