I have my 84 year old grandmother's financial and medical POA. She has dementia and also has a drinking problem. My aunt is her youngest child and is a horrible person, she is a sociopath in my opinion. She takes my Granny to the bank everyday to get money and encourages her to drink and smoke by taking her to buy beer and cigerettes, my Granny does not drive. My aunt's incentive for taking her to the bank is gas money. I had the bank put a $50 daily withdrawal limit on the account. Granny recently burned her legs on space heaters because she fell asleep sitting in front of them, probably after drinking. I have contacted APS before about checks that Granny was writing to family members as loans but they never paid the money back and was told that if Granny signed the checks, there was nothing they could do. What can I do about the sociopath aunt? She knows that Granny has dementia and was told by Dr.s to stop drinking and smoking because of high blood pressure.
