I went and tried to visit with my dying mother however my step brother who has POA said I was no longer welcome at her home. Someone had reported him for elder abuse recently and he insists that I had called. While I was there a nursing staff was there giving him instruction's on how to give her medication. He was highly agitated that I was there. Told me that I was no longer welcome there and then when I said I had every right to see my mother he told me to leave. He then acted like he was calling the police by the way they never showed up. The nursing staff tried to calm him down however he kept saying that he had POA and he didn't want me there. Will the nursing staff have to report what they saw to their supervisor as I'm pretty certain they were there on the behalf of Protective Services.
It is a red flag that her son was reported for elder abuse.
As POA for my folks I would not hesitate to keep someone away from them if I felt it was harmful in any way to their well being. I don't know if that is the case here however.
I do agree with having someone check on her welfare but the police are not the ones to do it. Unless the situation is obviously harmful or abusive, they don't really have the training to handle this. They would most likely only file a report with APS. I think that is where you should start. Make a call and have them send an investigator.
It is unfortunate for you that your mom lives with your step brother because he has every right to decide who can enter his home. I think your best hope is to try to find a third party to mediate and find a way to set up some visiting hours for you. Whatever the back story is here, the number one priority is respecting the needs and wishes of your mother, you both may need to compromise and eat some humble pie in order to make that happen.
