While I was at work...he has Parkinson's dementia .....a so called friend of his helped him. I knew nothing about this...and had no idea where he had gone to. I went to the police and reported him as a missing person because I had no idea what had happened to him and was concerned for his welfare. The police found him but he told them he didn't want me or anybody else to know where he was. I believe this friend has now taken POA and he has closed our bank accounts and taken the money. I now know that my husband was admitted to a mental hospital and is now in a nursing home. Is there anything I can do to stop this person from having POA?
