Alleged killer Lucy Letby has been labelled "a poisoner at work" as Manchester Crown Court heard harrowing details surrounding the death of one of the former nurse's seventeen victims.
The former nurse is charged with seven counts of murder and fifteen counts of attempted murder.
Lucy Letby, 32, allegedly carried out a year-long killing spree from June 2015 while working at the Countess of Chester Hospital in Chesire, UK.
The suspicious deaths that occurred between June 2015 and 2016 were initially investigated in May 2017.
In total, five girls and two boys died, while another five girls and five boys were saved by a team of doctors and nurses.
As the case entered its third day, the courtroom was subject to horrific details surrounding the death of 'Child I'.
The prosecution said that the baby in question was attacked by Letby on four separate occasions before succumbing to the nurse's alleged extreme violence.
Having honed her killing method on Child C, Letby forcibly injected air into Child I's stomach via a nasal gastric tube - just days after attempting to murder another child in a similar manner.
However, following CPR by other members of the ward, the child survived - only for the baby to fall ill once again one hour later while in Letby's presence. Child I later passed away.
Bizarrely, Letby sent a sympathy card to Child I's parents - something the former nurse accepted was not protocol during a police investigation.
Earlier in the week, Manchester Crown Court heard shocking details on the cause of deaths surrounding Child A and C and how the murderer honed her killing method over a single week.
The families of victims heard that Letby killed her first baby by injecting air into the boy's bloodstream, before changing her deadly method just six days later on Child C when she forcibly injected air into a baby's stomach via a nasal gastric tube.
The 32-year-old from Hereford has denied all murder charges, including fifteen counts of attempted murder.
While the babies cannot be named for legal reasons, family members of the victims were present in the public gallery at the trial's opening.
The trial continues at Manchester Crown Court.
