ON Monday, October 10, the jury was told Lucy Letby was “a poisoner at work”, as the Countess of Chester Hospital nurse’s trial heard opening evidence from the prosecution.
Letby is accused of the murder of seven babies at the hospital’s neonatal unit between June 2015 and June 2016. She has pleaded not guilty to all of those charges.
The 32-year-old is also accused of the attempted murder of 10 babies, some on multiple occasions. Letby has denied all 15 attempted murder charges.
Prosecuting at Manchester Crown Court, Nicholas Johnson KC told the jury that, prior to January 2015, the mortality rate at the Countess of Chester Hospital’s neonatal unit was comparable with other similar hospital units across the UK.

On Monday the former Countess of Chester Hospital nurse also denied fresh charges of attempted murder.
The new charges relate to existing alleged victims, meaning Letby is now charged, in some cases, of attempting to murder a baby on multiple occasions.
For clarity, Letby - appearing at Manchester Crown Court on Monday wearing dark-coloured clothing - was rearraigned on all 17 existing charges, plus the five new ones.
Letby pleaded not guilty to all 22 charges, for offences alleged to have happened between June 2015 and June 2016 at the hospital’s neonatal unit.

On Monday the court heard how Lucy Letby injected air into new-born twins, leading one to die and one to suffer a non-fatal-collapse, within just 28 hours of each other, a jury has been told.
Prosecuting at Manchester Crown Court on the afternoon of Monday, Nicholas Johnson KC gave details of the prosecution’s case for two of the babies named on the charges.
Due to reporting restrictions, the babies are named as Child A and Child B. Child A, a boy, and twin sister Child B were born at the Countess of Chester Hospital in June 2015 and placed in the neonatal unit, a special area of the hospital which looks after sick and/or vulnerable babies.
The court heard Child A died just 90 minutes after being passed into the care of Letby, while Child B suffered a non-fatal collapse 28 hours later, where Letby was present despite not being the designated nurse.

On Tuesday, October 11, alleged killer nurse Lucy Letby was ‘caught trying to attack a new-born twin’ by the child’s mother, a court has heard.
Prosecuting at Manchester Crown Court, Nicholas Johnson KC said Child E was the twin brother of Child F - with Child F being allegedly poisoned with insulin.
Mr Johnson said it was at 9pm on August 3, 2015, when the mother decided to visit her twin sons, and “interrupted Lucy Letby who was in the process of attacking Child E”, although the mum “did not realise it at the time”.
Child E was ‘acutely distressed’ and bleeding from the mouth.

On Wednesday, October 12, a consultant paediatrician at the Countess of Chester Hospital walked in on neonatal nurse Lucy Letby ‘trying to kill’ a 1lb 8oz baby that had been born only 97 minutes earlier, a court has heard. 
Nicholas Johnson KC continued his opening of the prosecution case at Manchester Crown Court.
Mr Johnson said it was the prosecution’s case Letby was trying to kill ‘Child K’ when consultant paediatrician Dr Ravi Jayaram walked into the nursery room, as Child K was awaiting transfer to Arrowe Park Hospital.
Child K had been born in February 2016, very premature. The court heard births of this type would normally be delivered at Arrowe Park or Liverpool Women’s Hospital, but there was not enough time for this to be possible, so Dr Jayaram was present for the birth at the Countess of Chester Hospital.

On Thursday, October 13, the alleged killer Countess of Chester Hospital nurse wrote: "I AM EVIL I DID THIS” in a note found at her Chester home.

Concluding the prosecution opening at Manchester Crown Court, prosecutor Nicholas Johnson KC showed the court notes which Letby had written, and which police had found at the time Letby was arrested at her Chester home in July 2018.

Mr Johnson said: "On July 3 she was arrested at her home, where the house was searched.

"In addition to some of the paperwork, they found some other interesting items.

"There were some Post-it notes with closely written words on them, some of which included the names of some of her colleagues."
