Mil accuses DH of poisoning her

Your supportive messages have been so comforting, I got myself all worked up about the word 'investigating'. She's still in hospital although of course we can't visit, and when we suggested a UTI they were a bit shirty and said naturally they had tested for everything. (Ooops!)
But she's on antibiotics so maybe that has been part of the problem.
They are talking about a Care Home which will be difficult at the moment with all this virus amongst (really old) people.
Anyway - your help has been appreciated.

My MIL accused my DH of stealing her pension , he had POA and collected it , paid any bills for her, gave her the receipts and change yet she told other members of the family he was taking her money, it wasnt very nice for him , but thankfully no one took it seriously , as it just wasn’t true, She was diagnosed with Alzheimer’s shortly after , which explained her behaviour at the time,, Doctor,s and police must be used to dealing with these complaints from the elderly , but it is upsetting for those accused when they are just trying to help,
