But only one nurse was at all those deaths, so that’s what made her suspicious, and accordingly warranted the investigation in which the other pieces of evidence were found.
Then there’s the fact that she had a lengthy trial, with a KC I think - the most senior barrister you can have, and her defence team apparently chose not to call very many defence witnesses in support, which in itself is odd, if there were so many flaws with the prosecution evidence and other explanations for the deaths. And the case has now been looked at, and rejected, twice by the Court of Appeal.
I haven’t watched the Netflix doc tbh because I don’t like true crime so maybe I’ve missed something but it does seem she’s had due process, I guess we’ll see what happens with the ccrc though.
