A note of medications given to a baby boy as he fought back from the brink of death was among items found under nurse Lucy Letby’s bed.

The record of emergency drugs provided to the infant was written on a paper towel during his 30-minute resuscitation at the Countess of Chester Hospital’s neonatal unit.

Letby, 33, gave rescue breaths to the youngster, Child M, after she responded to his cot monitor alarm.

Earlier she had injected air into Child M’s bloodstream and also poisoned his twin brother, Child L, with insulin.

She denied she kept it as a souvenir of her attack.

The paper towel and a blood gas reading for Child M were both found in a Morrisons bag in Letby’s bedroom following her arrest.

Also in the same bag was a number of shift handover sheets which also should not have left the hospital.

Letby had a total of 257 such sheets in her possession which contained the names of children cared for on a given shift.

Twenty-one of the sheets included the names of babies she was said to have harmed.

Letby denied she had purposely collected them.

Giving evidence, she said: “They have no meaning to me at all. I have copious pieces of paper and cards that I have not thrown away my whole life.”

Jurors heard some of the sheets were found in a bin bag in the garage at her home in Westbourne Road, Chester.

However, one was found in “pristine condition” dated June 1 2010 – her first day of work as a student at the neonatal unit.

It was found inside a keepsafe box with roses on it, the court heard.

Letby denied getting a “thrill” out of photographing a sympathy card she sent to the parents of a baby girl ahead of the youngster’s funeral.

She retained the image on her mobile phone which was taken on the unit where she murdered the infant, Child I, weeks earlier.

The nurse told police: “I often take pictures of any cards that I have sent, even birthday cards – anything like that. I often take pictures of them.

“It was upsetting losing (Child I) and I think it was nice to remember the kind words that I hoped I’d shared with that family.

Letby wrote on the card: “There are no words to make this time any easier.

“It was a real priviledge (sic) to care for (Child I) and get to know you as a family – a family who always put (Child I) first and did everything possible for her.

“She will always be a part of your lives and we will never forget her.

“Thinking of you today and always – sorry I cannot be there to say goodbye.

“Lots of love Lucy x.”

Another image captured on her phone was a thank you card brought in by the parents of twin boys who were unaware that Letby had murdered one and attempted to murder the other.

Letby also denied she was “checking up” on the parents of her victims by searching them on Facebook.

She said: “They’re just people that have crossed my mind at that time. It’s general curiosity that I look at a lot of people.

“It’s a common pattern of behaviour for me. I think of somebody and I look them up.”
