Jabbey (Letby case is a miscarriage of justice)
@Jabbey20
Exhausted registered nurse. Mum of two little cheeky toddlers. Lucy Letby is innocent.




@markjurgenmayes @MartynPitman @cheshirepolice Evans was asking about Letby's shift 11/12 October 2017.



In the case of Baby L, Lucy Letby went off shift at 8pm on 9th April and was off duty for several days. Yet Baby L's hypoglycaemic episode continued all through the next day, until the afternoon of the day after that! Lucy Letby did not return to work during this period. The prosecution alleged that on 9th April Lucy Letby poisoned his dextrose bags with insulin, yet within hours of her going off duty his dextrose bag was replaced with a new one, and a second one 24 hours after that. Here is how Professor Hindmarsh explained what might have happened: Hindmarsh: "The giving sets are plastic and insulin is a protein and it sticks very nicely to plastic. So in your giving set as well you would have insulin stuck potentially on to the walls of the tubing from which it could fall off over a period of time as well." (The giving set is the tubing set that connects an infusion bag with the catheter or long line. With dextrose, it doesn't have to be changed with every bag change.) In cross-examination, Hindmarsh admitted that he didn't actually know how sticky insulin might operate: Myers: "Is it the case that sticky insulin could be operative over a certain period potentially?" Hindmarsh: "I don't think anybody's actually done those kind of studies, to be honest, and I think the answer is we simply don't know." It's also worth pointing out that it wasn't known whether the giving set was actually changed when the new dextrose bags were put up. There was contradictory testimony about it. Hindmarsh: And do we also take it as a given that when they're doing that procedure, the whole giving system is changed as well? NJ: No. Hindmarsh: We don't know? NJ: No. Hindmarsh: Right. Nevertheless Nick Johnson settled on this theory as being the explanation for the continuing hypoglycaemia. From his closing speech: "We had some evidence about whether giving sets are changed and whether they're not changed; but as Professor Hindmarsh explained to us, an explanation, and a reasonable explanation for these results, is that there was insulin that had stuck to the plastic of the giving set. That even though the bag was changed for bags that didn't have insulin in, the insulin was still coming off the giving set, and therefore in ever-diminishing quantities; but it was still affecting the blood sugar results. So the fact that Lucy Letby wasn't there after about 8pm, we suggest, doesn't exculpate her at all." I find it unbelievable that Lucy Letby was convicted based on this highly speculative, unresearched expert evidence from Professor Hindmarsh. He clearly doesn't know anything about insulin adsorption and how it might behave in this situation - it's not within his field of expertise. Yet his expert testimony on this was accepted by the court. I've been looking into this and can say that he (and Nick Johnson) got this completely wrong! I will post more about it later this week.

















@MartynPitman If Jayaram had truly caught Letby "virtually red-handed" trying to dislodge an infant's breathing tube in February 2016, it is inexplicable that this definitive eye-witness evidence was not presented to the grievance panel in late 2016 to shut down Letby's complaints instantly.
