Think it's likely that there were many more cases before hand. I personally found Dr Gibbs description of the death toll usually averaging between 2-4 per year a little high for a level 2 of that size. I work with a level 2 that is double the size and tbh 4 deaths per year would definitely be a bad year, for babies that actually made it to NNU.I have not read everything about this case so apologies if I am missing some important factors. I find it odd that she just started killing when she was fully trained- so many other types of killers mistreat animals or do other destructive acts early on. I also keep thinking that as with fire starters, she some how wanted to threaten lives to see if she could save them but the whole "game" was a death spiral. IMO.
Is there any evidence that she interfered with some babies and they survived? Or was there only research into the deaths?
I am also curious if there was counseling or some kind of procedure for staff after a death. You know how they remove LE from regular duty right after a shooting? Knowing that there will be trauma. Is there any hospital procedure like that? It seems that she was just doing more shifts.
Regards the animals, they weren't 'out of the picture' as LL scrawled ramblings about her deceased pets whilst reflecting on the babies who were killed.
It seems it wasn't 'just' a 12 month killing spree, hence they are now investigating 4000 babies that LL cared for. I would agree that to wake up one days and go on a killing spree would be odd.
In relation to the shift patterns and LL doing extra. It seems she was not the only one..
Myers then asked: “Had the unit been as busy as this in all the years you worked there?"
Letby said: “No. It was increasingly busy at this period. A lot of staff were drained physically and emotionally. The unit was very busy, lots of people were doing additional shifts and changing shifts at the last minute and it did start to have an effect on everybody."
