It's funny how we come away with different perceptions. To me, the last couple days testimony were much more a win for the defence.
The prosecution's opening statement framed it as the only explanation would be LL caused deliberate air embolism.
Yesterday we heard that Baby A's care hadn't been straightforward and significantly the first act LL or possibly her colleague did just after 8pm was connect up fluids which hadn't been given for the previous 4 hours.
Today we heard the expert say that air seen on the x-ray was consistent with air embolism but acknowledge there are various other possible causes. He acknowledged his sample size was very small, consisting of only 38 babies under 2 months of whom 8 showed similar gases. He confusingly stated there were "no unexplained cases" of gases in that location, despite also saying the explanation for some was "sudden unexpected infant death", which in layman's terms means "sometimes babies die unexpectedly and there isn't an obvious cause" or "unexplained" - which doesn't mean you couldn't find a cause if you looked or that they're all the same cause, but you have to decide how much investigating you're going to do for each death and it might be no amount would find the cause because the evidence is long gone. I'm not sure if he's suggesting there's a difference between this and SIDS/SUID apart from they have a theory the LL injected the baby with air - or why the defence didn't pick up on that - even to clarify what it meant for the benefit of the jury?
So far as regards the blotchiness - the camera was to be brought in for Baby B not A, it's B where it was documented. So far we have one doctor who said it was very striking and he'd never seen anything like it, but also completely forgot it and didn't remember it the second time he saw it either but only when being interviewed about the second case a few years later. We have one nurse who has just mentioned it and hasn't been cross examined yet. I don't doubt that this strange pattern appeared on Baby B. We'll wait to hear if the nurse also only remembered it much later.
In itself, it isn't significant at all though. If the prosecution expert witness can explain who the blotchy pattern isn't unknown to other doctors/nurses and what the identified cause was in those cases, it would add evidence to these babies dying of similar causes. Presumably the argument will be that this is a symptom of air embolism because although these doctors found it really strange, there are records of it in other cases of air embolism.
At that point, it begins to look a lot more likely that several of these babies died or collapsed from air embolism as the prosecution allege. That still doesn't get us very close to: "this was caused intentionally by someone".
We've also started to poke holes in a lot of the things the prosecution has alleged about notes being made to cover things up - we've acknowledged that retrospective notes are not unusual, and now that rough times are estimated after the fact and so there's nothing particularly unusual about notes seeming to suggest someone was in two places at once.
We have also begun to touch on why your signature appears on documents for patients other than your assigned patient and that it is fairly normal to conduct routine hourly observations for other nurses' patients.
