Police investigating a spate of baby deaths at a UK hospital found a note reading ‘I’m evil I did this’ at the home of a nurse accused of killing her, a court said on Wednesday .

Another read: “I don’t deserve to live. I killed her on purpose because I’m not good enough to take care of her. I’m a terribly evil person.”

Newborn nurse Lucy Letby, 32, stands trial at Manchester Crown Court in northwest England, charged with seven murders and 15 attempted murders.

The crimes, which she denies, allegedly took place between June 2015 and June 2016 at the Countess of Chester Hospital in Chester.

Prosecutor Nick Johnson said the notes were found among papers and other notes that also contained “many protestations of innocence”.

He told jurors at the end of his opening statement that Letby was assigned clerical duties when she became a suspect prior to her July 2018 arrest.

A subsequent police search of their Chester home found papers relating to many of the children who died or collapsed.

The note shown to the court reading “I’m angry, I did this” was written in capital letters.

The attorney said other papers found indicated Letby was frustrated at not being allowed to return to the neonatal unit and claims she was innocent.

“I did nothing wrong and they have no proof, so why did I have to go into hiding?” one read.

The trial, which opened Monday and is expected to last six months, was told Letby used various methods to attack the newborns.

They included insulin poisoning and injected air into her bloodstream, causing her to stop breathing, prosecutors have claimed.

Most babies are born prematurely, including twins and triplets. The youngest was just a day old.

The charges relate to 17 children, none of whom can be named due to a court order. Some have reportedly been attacked more than once.

Defense attorney Ben Myers, representing Letby, told jurors it would be “appallingly unfair” to convict his client without hearing evidence.

He told them the defense would argue that in some cases it was not clear why the child died or why his condition deteriorated.

Letby is a “dedicated nurse” and only wants to look after the babies she cares for, he said.

“The defense says they are not guilty of intentionally harming or killing a baby,” he added.

“Anyone who thinks of this as some kind of closed deal is very wrong here.”
