A baby boy who was allegedly murdered by nurse Lucy Letby suffered a liver injury that was akin to a road traffic collision, her trial has heard.

The 33-year-old nurse is said to have attacked the new-born infant on a day shift on 23 June, 2016 at the Countess of Chester’s neonatal unit – following her return from a holiday to Ibiza.

Child O was born in good condition, Manchester Crown Court heard, until he suddenly collapsed two days later in the care of Letby and went progressively downhill as medics failed to revive him.

On Wednesday, paediatric pathologist Dr Andreas Marnerides said Child O died partly due to an “impact-type” internal liver injury – discovered after the baby’s death.

Jurors were shown post-mortem examination photographs which showed two separate sites of bruising, as well as areas of a blood clot.

Dr Marnerides, who practises at London’s St Thomas’ Hospital, explained the photograph showed “extensive haemorrhaging into the liver”, which he had only seen previously in a road traffic collision and in non-accidental assaults from parents or carers.

He added: “I cannot convince myself that in the setting of a neonatal unit this would be a reasonable proposition to explain this. I don’t think CPR [cardiopulmonary resuscitation] can produce this extensive injury to a liver.”

Asked what he believed to be the cause of death, Marnerides said: “In my view, the cause of death was inflicted traumatic injury to the liver, profound gastric and intestinal distension following acute excessive injection/infusion of air via a nasogastric tube and air embolism due to administration into a venous line.”

The prosecution say that Letby murdered Child P, one of Child O’s triplet brothers, on the following day shift.

Letby denies the murders of seven babies and the attempted murders of 10 others between June 2015 and June 2016, while she was working as a neonatal nurse.

One day later, police charged Letby with eight counts of murder and 10 of attempted murder. The charges related to a period between June 2015 and June 2016.

She pleaded not guilty to the charges at a hearing at Manchester Crown Court in October 2021.

In June last year, Letby had one not guilty verdict recorded for one of the murder charges.

It meant that when she went on trial in October last year, she faced seven murder charges (five boys and two girls) and 10 attempted murder charges (five boys and five girls).

Letby denies the alleged offences.
