Child E's parent's comments and those of the Dr I personally find the most damming evidence so far. I personally trust the parent's versions of events reasonably. Why would she fob off the mother when it was a bleed so large that apparently, the Dr had never seen it in a baby of that size?
 
How is this relevant?

It's a valid question, because its answer leads to further questions and builds a picture of the person, their strengths and vulnerabilities. That can also be enormously useful in interview, if you know what buttons to push!

You can bet the police went into her background, home life, school history, Uni experience, work history, medical history, financial history, online behaviour (we know), phone history, social life and relationships etc with a fine toothcomb.
 
2:30pm

The TPN bag was delivered up to the ward at 4pm that day.
On that nght shift, the designated nurse for Child F, in room 2, was not Letby.
Letby had a single baby to look after that night, also in room 2.
There were seven babies in the unit that night, with five nurses working.

2:33pm

Letby and the designated nurse signed the prescription chart to record the TPN bag was started and administered via a long line at 12.25am.
A TPN chart is a written record for putting up the bags, and was used for Child F. It includes 'lipids' - nutrients for babies not being given milk.
Letby signed for the TPN bag to be used for 48 hours.

 
2:40pm

There are two further prescriptions for TPN bags, to run for 48 hours.
Following the conclusion of a Letby night-shift, after the administration of a TPN bag Letby had co-signed for, a doctor instructed the nursing staff to stop the TPN via the longline and provide dextrose (sugar to counteract the fall in blood sugar), and move the TPN to a peripheral line while a new long line was put in.
All fluids were interrupted at 11am while a new long line was put in.

 
2:49pm

"All experienced medical and nursing members of staff would know the dangers of introducing insulin into any individual whose glucose values were within the normal range and would know that extreme hypoglycaemia, over a prolonged period of time, carries life threatening risks.
"No other baby on the neonatal unit was prescribed insulin at the time."

 
2:51pm

Mr Johnson: "To give Child F insulin someone would've had to access the locked fridge, use a needle and syringe to remove some insulin, or, if they didn't do it that way, go to the cotside and inject the insulin directly into the infant through the intravenous system, intramuscular injection, or - and this is what we say happened - via the TPN bag."

 
Thanks for all the updates!

I think this one may have been missed

2:48pm

Child F's blood glucose increased, before falling back. A new bespoke TPN was made for Child F, delivered at 4pm.
The prosecution say this could not have been the same one fitted to Child F at noon that day which would have been either a bespoke bag which Lucy Letby co-signed for, or a stock bag from the fridge.
Mr Johnson said Child F's low blood sugar continued in the absence of Lucy Letby.
Child F's blood sample at 5.56pm had a glucose level was very low, and after he was taken off the TPN and replaced with dextrose, his blood glucose levels returned to normal by 7.30pm. He had no further episodes of hypoglycaemia.
"These episodes were sufficiently concerning" that medical staff checked Child F's blood plasma level. The 5.56pm sample recorded a "very high insulin measurement of 4,657".
Child F's hormone level of C-peptide was very low - less than 169.
The combination of the two levels, the prosecution say, means someone must have "been given or taken synthetic insulin" - "the only conclusion".
"That, we say, means that somebody gave Child F synthetic insulin - somebody poisoned him."
 
One last thing. I believe LL may have been an only child. I wonder if she lost a sibling in childhood and what the circumstances were?

All just my very non-expert opinion

I'd also wondered that. I guess it's natural to try to look for a motive. I wonder how many of the babies on the ward were twins, I expect they have a higher probability of needing additional care than a single birth, so perhaps that would explain why in any crop of infant deaths you'd see more examples.
 
2:55pm

Medical experts Dr Dewi Evans and Dr Sandie Bohin said the hormone levels were consistent with insulin being put into the TPN bag prior to Child F's hypoglycaemic episode.
"You know who was in the room, and you know who hung up the bag," Mr Johnson told the jury.
Professor Peter Hindmarsh said the insulin "had to have gone in through the TPN bag" as the the hypoglycaemia "persisted for such a long time" despite five injections of 10% dextrose.
Professor Hindmarsh said the following possibilities happened.
That the same bag was transferred over the line, that the replacement stock bag was contaminated, or that some part of the 'giving set' was contaminated by insulin fron the first TPN bag which had bound to the plastic, and therefore continued to flow through the hardware even after a non-contaminated bag was attached.
"There can be no doubt that somebody contaminated that original bag with insulin.
"Because of that...the problem continued through the day."

 
3:00pm

Letby was interviewed by police in July 2018 about that night shift.
She remembered Child F, but had no recollection of the incident and "had not been involved in his care".
She was asked about the TPN bags chart. She said the TPN was kept in a locked fridge and the insulin was kept in that same fridge.
She confirmed her signature on the TPN form.
She had no recollection of having had involvement with administering the TPN bag contents to Child F, but confirmed giving Child F glucose injections and taken observations.
She also confirmed signing for a lipid syringe at 12.10am, the shift before. The prosecution say she should have had someone to co-sign for it.
"She accepted that the signature tended to suggest she had administered it."
"Interestingly, at the end of this part of the interview she asked whether the police had access to the TPN bag that she had connected," Mr Johnson added.

 
3:02pm

In a June 2019 police interview, Letby agreed with the idea that insulin would not be administered accidentally.
In November 2020, she was asked why she had searched for the parents of Child E and F. She said she thought it might be to see how Child F was doing.
She was asked asked about texting Child F’s blood sugar levels to an off- duty colleague at 8am. She said she must have looked on his chart.

 
3:03pm

Mr Johnson: "The fact it was done through the TPN bag tells you it wasn't a mistake - whoever was doing it was to avoid detection.
"Only a few people had the opportunity.
"We suggest there is only one credible candidate for the poisoning. The one who was present for all the unexpected collapses and deaths at the neonatal unit."

 
3:07pm

Child G suffered bleeding on her lungs and had nine blood transfusions, with a number of 'septic' or 'suspected septic' episodes requiring antibiotics, but improved and was transferred to the Countess of Chester Hospital's neonatal unit in August, and was clinically stable, being fed expressed breast milk.

3:09pm

On the night in September, Child G was in nursery 2, with a designated nurse (not Letby). There were seven babies in the unit, with five nursing staff.
Letby's assigned baby that night was in nursery 1.

 
3:03pm

Mr Johnson: "The fact it was done through the TPN bag tells you it wasn't a mistake - whoever was doing it was to avoid detection.
"Only a few people had the opportunity.
"We suggest there is only one credible candidate for the poisoning. The one who was present for all the unexpected collapses and deaths at the neonatal unit."

Why would she text an off duty colleague a blood sugar reading?
 
Do any of the medical professionals in here know if there are any markings visible to the naked eye when insulin binds to a bag or plastic?
 
Lucia de Berk's alleged poison was digoxin. Digoxin is also present in the body naturally. Misinterpretation of the autopsy results of digoxin levels led to the initial charges and conviction.
Only in the case of one child. The child had recently been intensively treated with digoxin. It gets stored in the body in certain organs. After death, cell walls break down, stuff leaks everywhere. The digoxin was found in some bloody watery fluid taken from the body at a second autopsy. There is no way to say where it came from nor what it’s concentration had been e.g. in the blood. A high level in the blood at death would indicate poisoning. Hours later, found in some body cavities at a second autopsy, it says nothing.
 
3:11pm

At 2am, a feed had shown minimal aspirated of partially digested milk. The nurse took her scheduled one-hour break.
"Nothing is recorded on who was asked to keep an eye on Child G," Mr Johnson said.

3:14pm

At 2.15am, the shift leader said she was sat with Lucy Leader when she heard Child G vomiting, along with Child G's monitor alarm going off.
They ran into her nursery. Child G had vomited violently and suffered a collapse.
The prosecution said medical records suggest the shift leader nurse's memory of being with Lucy Letby for a period of time before this event cannot be accurate.

 
3:17pm

The prosecution say despite Child G's stomach being 'pretty much empty' prior to her feed, 45mls of milk was aspirated from her NGT.
But, the prosecution say, 45mls of milk had been administered for her feed, which then did not explain what accounted for the vomit.
Subsequent x-rays showed air in the abdomen and intestines.
Child G suffered further deteriorations. During intubation, a doctor noticed bloodstained fluid from the trachea - something the prosecution say was consistent with that seen in other collapses in the case so far.
