I know I probably should but it's a long story.
My aunt is 84 and has dementia she lived alone in a house owned by family. At the start of COVID an old friend of hers turned up and said he didn't want her living alone and moved in with her. I don't know this person but he owns a shop she used to use. To be honest though, as I live an hour away it was a relief that he was there to keep an eye on her. My aunt loves him. He was living as her lodger but not paying rent or anything. My aunt always said they paid half the food etc but I have no way of knowing the truth. He has had her bank card for years (as he owed her £10k apparently and was paying it back into the bank each week-or so she said).
He moved out over Christmas but has been going to see her and take her food etc. Anyway this made her extremely depressed culminating in an overdose in January, when finally, after 2 years of me fighting for social services support, they decided she didn't have capacity and have put her in 24 care.
Whilst she was in hospital the LPA for finances finally came through and I've checked her bank account. Over £2k was withdrawn in cash in December alone and another £250 whilst she has been in hospital. Ex lodger said that he had to pay some bills for her which he has done but as far as I can tell they equate to less than £500. No sign of the other cash. I cancelled the card and moved the money to an ISA.
Today I found a bank statement for another account which had £130 withdrawn from it on 31st January, the last lot of cash withdrawn from the other account was £100 on 25th January. She was in hospital from 11th January. He has never told me he had this card or even that it existed.
Even more suspiciously, in Oct there was a 1p transaction from this card to the ex lodgers shop. Almost like checking the card was valid.
I don't know what to do. This man goes to see her all the time and my aunt loves him, if I go to the police then that will end. Also the ex lodger clearly believes that she owns the house herself, which I'm wondering might be a motive for this.
He no longer has access to anything but I should call the police shouldn't I?
