Nurse Lucy Letby poisoned babies with insulin, trial toldon October 10, 2022 at 3:18 pm

A “poisoner was at work” at a hospital where there was a “significant rise” in the number of healthy babies dying, a court has heard.

Lucy Letby has been accused of murdering five baby boys and two girls, and attempting to murder of 10 other babies at Countess of Chester hospital.

Nick Johnson KC, prosecuting, said she was a “constant malevolent presence” in the hospital’s neonatal unit.

Ms Letby, 32, of Hereford, denies 22 charges at Manchester Crown Court.

Opening the prosecution case, Mr Johnson said the Chester institution was a “busy general hospital… like so many others in the UK”.

However, he said that “unlike many other hospitals… within the neo-natal unit at the Countess of Chester Hospital, a poisoner was at work”.

“Prior to January 2015, the statistics for the mortality of babies in the neo-natal unit at the Countess of Chester were comparable to other like units,” he said.

“However, over the next 18 months or so, there was a significant rise in the number of babies who were dying and in the number of serious catastrophic collapses.”

He said the increases were noticed by hospital consultants, who were concerned that “babies who were dying had deteriorated unexpectedly”.

Medics also noted that babies who had collapsed “did not respond to appropriate and timely resuscitation” and that others “collapsed dramatically, but then, equally dramatically, recovered”.

“Having searched for a cause, which they were unable to find, the consultants noticed that the inexplicable collapses and deaths did have one common denominator,” he said.

“The presence of one of the neonatal nurses and that nurse was Lucy Letby.”

Mr Johnson told the court that as medics could not account for the collapses and deaths, police were called in and conducted a “painstaking review”.

“That review suggests in the period between mid-2015 and the middle of 2016, somebody in the neonatal unit poisoned two children with insulin,” he said.

“The prosecution say the only reasonable conclusion to be drawn from the evidence you will hear is that somebody poisoned these babies deliberately with insulin.”

He told the jury that both babies were poisoned within a few days of being born.

“There’s a very restricted number of people who could have been the poisoner, because entry to a neonatal unit is closely restricted,” he said.

“Lucy Letby was on duty when both were poisoned and we allege she was the poisoner,” Mr Johnson said.

He said all the deaths and collapses were “no accident” and were not “naturally-occurring tragedies”.

“Many of the events in this case occurred on the night shifts,” he said.

“When upon Lucy Letby was moved on to day shifts, the collapses and deaths moved to the day shifts.”

“They were all the work… of the woman in the dock, who, we say, was the constant malevolent presence when things took a turn for the worse for these 17 children,” he said.

The jury has been told the trial may last up to six months.

The case was adjourned until Monday.
