A neonatal hospital nurse in Britain accused of killing seven babies and trying to kill ten others poisoned two infants deliberately with insulin, a British prosecutor said Monday.
Lucy Letby, 32, has been charged with murder in the deaths of five baby boys and two girls and the attempted murder of five boys and five girls while she worked at the Countess of Chester Hospital in northwest England between 2015 and 2016.
Let earlier pleaded not guilty to the charges.
Opening her trial at Manchester Crown Court, prosecutor Nick Johnson said that beginning in 2015; the hospital saw a significant rise in the number of babies dying or suffering “serious catastrophic collapses.”
“Babies who had not been unstable at all suddenly deteriorated. Sometimes babies who had been sick but then been on the mend suddenly deteriorated for no apparent reason,” he told the jury.
He said that when doctors couldn’t find a cause, police were called in and conducted a review that suggested someone in the neonatal unit had poisoned two infant boys with insulin two days after they were born. Johnson said the two boys’ blood sugar levels dropped to dangerous levels, but both survived after help from medical staff.
Johnson said Letby was on duty when both were poisoned. He added that prosecutors believed the collapses and deaths of all 17 babies were the work of Letby, who he described as a “constant malevolent presence” at the hospital’s neonatal unit when the children collapsed or died.
The first baby allegedly targeted by Letby was a prematurely born boy killed at just a day old in June 2015, Johnson said.
The prosecutor alleged that Letby injected air into the child’s bloodstream. A medical expert said the most likely reason for the baby’s collapse was air administered deliberately “by someone who knew it would cause significant harm.”
Family members of some of Letby’s alleged victims sat in the courtroom while Letby’s parents were also present.
The trial is expected to last weeks, if not months.
Police launched an investigation into the deaths of several babies at the hospital in May 2017. Let was arrested three times in connection with the deaths before she was charged in November 2020.
