My grandmother has dementia and I just found out she has been in a hospital since February. I was never contacted -- I live in MN and have been trying to reach her for two months. I had the police sent to her apartment and found out she was no longer living there. The manager of the apartments will not give me any information on what happened to my grandmother's personal items. My grandma thinks she still lives there and has been writing rent checks (I don't know if she has actually sent any).
What do I need to do to become her power of attorney?
