A paediatric nurse has appeared in a UK court on charges of murdering eight babies and attempting to kill another nine.
Lucy Letby, 31, appeared at Manchester Crown Court via videolink from prison.
The charges related to her time at the Countess of Chester Hospital, and include the murders of five boys and three girls between June 2015 and June 2016.
Suspicions were first raised in 2017, when there was a disturbing rise in deaths at the neonatal unit, where Letby was a celebrated member of staff.
An investigation by the hospital found that premature babies had died following heart and lung failure, but were unusually impossible to revive.
A conviction for eight murders would make Letby Britain's worst child killer, but neighbours who spoke to media when Letby was first arrested said they were in disbelief someone so "dedicated to her job" could be accused of anything like what had been suggested.
One told the Chester Chronicle they had known her since she was just 3 and "she was lovely, she always has been".
Others said Letby kept to herself and didn't know too many people in the area.
After that initial 2018 arrest, several mothers wrote online of their horror that their children were cared for by Letby.
One said her daughter was cared for by her "every day for seven weeks".
Another recognised her instantly as a nurse who was involved in the care of two of her grandchildren.
In an interview with a local newspaper, Letby revealed why she loved nursing.
"I qualified as a children's nurse from the University of Chester in 2011 and have been working on the unit since graduating," she said.
"I also worked on the unit as a student nurse during my three years of training. My role involves caring for a wide range of babies requiring various levels of support.
"Some are here for a few days, others for many months and I enjoy seeing them progress and supporting their families."
Her trial has been set for January 11 next year, with the possibility that it could be delayed.
Letby is yet to enter a plea and remains in custody.
