If you were previously on the fence about Lucy Letby’s guilt, have the Thirlwall findings swayed you either way?

I personally have always thought she is guilty, and even more so since the report findings were published.

YABU - still on the fence/ still believe she is innocent

YANBU - she’s guilty

Four in nine months, that we know of.

Well Dr Evans actually does think there are another potential 2 insulin cases that the police should investigate. If she's connected to all four, which I expect she is, then even you might have to concede she's a poisoner (and the rest)

@kkloo there isn't an accidental explanation that's why. Insulin never goes into TPN bags.

Well they would be dismissed because the alternative is a nurse purposely injected insulin into bags to poison babies-and who would believe that? But now thanks to Lady Thirlwall, results like the ones tied to Lucy will be flagged up immediately. Because it does show poisoning.

The first thing I'd think would be that it was accidental but of course they weren't arsed checking.

How many odd insulin results is that altogether?

@Viviennemary yes and she actually said "you've said your goodbyes, want me to put him in this?" And the dad (I think) had to say "he's not dead yet" and she left sharpish. This was baby C and she wasn't designated nurse and shouldn't have been anywhere near him or his family anyway. But of course posters on here will cling to the idea this mystery nurse hasn't been identified as Letby (even though the dad described her and later recognised her seeing a photo even if he didn't know her name at the time-which makes sense as she wasn't supposed to be that baby's nurse) you can't justify it at all, but they'll try...

Sure the parents knew to baby was dieing. these weren’t full term babies. I don’t really know what happened there neither do you, this is based on recollection of a mother quite traumatised by what was happening, I don’t want to go into arguments of what happens when babies die. But to say she should not be working in this environment, I have had parents lie about my interaction with them. We are not allowed to defend ourselves. This was done not out of spite but because parents can keep their babies with them for longer.

I know that. But the baby was still alive. Those poor parents.

Whether that was Lucy Letby or not was questionable anyway, but I don't think we have any information about protocols for bringing cold cots into the room. It's hardly something you could hope to do unobserved, so I doubt whoever it was brought it in maliciously.

It is a vile thing to do. No better than bringing in a coffin before somebody dies. Sometimes I despair.

No, the results were unusual enough for the lab to phone the ward to discuss.
The ward didn’t follow up on that for whatever reason which is what I find shocking.
Thirlwall agrees that the results should have been investigated.

I thought these results were not found until 6 months after the fact.

Firefly1987 · 23/09/2026 20:27

Oftenaddled · 23/09/2026 19:36

Well, even if it does show insulin administration it's obvious that the only possible explanation isn't a nurse poisoning bags specifically.

So odd that we have two other results of the same type from that same lab, in a single year. One was just a trial, but still ... And why hasn't the other been prosecuted?

If she wheeled the cot into the room before the baby died that is not behaviour of somebody who should be working in this environment.

Yes, and it is the doctors on the ward who made the clinical decision. Absolutely, I agree it's a dreadful shame the proper tests weren't done.

The clinical decision made in response to these results was to disregard them as errors or lacking corroborative detail. That is what accurate enough for clinical use means

Think you will find a cold cot is taken to parents after a baby passes away this is normal practice, to stop or slow down detierortion of the body so parents can spend more time with them. I would like you to show me your proof she asked them to put a live baby in a cold cot?

Yes I accept that and this should have been followed up with repeat/forensic testing.
That’s not the same thing as the tests not being accurate though, the tests are highly accurate, they’re used every day in hospitals to make clinical decisions.

Not to see if someone has injected you with insulin. The tests were not made to catch a killers, they were to help with diagnosis of patients. They misused this test to try prove a hypothesis. It was believed but it doesn’t make it right.

She was definitely on medication during the trial, initially it was delayed for a week or so because she had moved prisons and been without her medication for a few days and it had a very bad effect on her so the trial had to be delayed.

But even trauma by itself can flatten emotions.

Also the people who say if that was them they'd be screaming and shouting in the courtroom must watch too much eastenders, people don't tend to go on like that in the courtroom.
Even the families of victims who have been raped and murdered tend to sit there quietly in the courtroom like everyone else does, no matter how much they might like to scream and shout and get up and attack the victim.

Edited

Agree. Medication and the weight of what’s happening. It’s her whole life at stake after all.

If its true Lucy Letby was on antidepressants during the trial, which is not surprising, then one of the things they do, is to flatten affect (ie emotions). It’s no wonder, she looked cold!

She was: she also had a diagnosis of hypothyroidism since childhood which I believe needs careful management and affects mood and energy

Because you’ve been accused of killing babies before so you know how you would react. Course you don’t none of us do. This had been going on for 3 years & she was imprisoned plus she was on a load of anti depressive medication. Because you’ve decided based on how she looks she is guilty let’s hope you never serve on a jury.

On the post you’re replying to the pp should look at the Lindy Chamberlain case. She had similar.

Right so you don't believe baby E's mum then. What happened to always believing the victims?

Nothing Baby E's mother said implies a crime. Her account was simply used as weak supporting evidence when prosecutors decided there had been a crime. It demonstrates that the baby was almost certainly unwell, which given that everyone agrees he died a few hours later, is not a surprising finding.
