My dad recently passed away and I am now being accused of things that just never happened.

8/22/16.... Susan, time to educate your siblings about Alzheimer's/Dementia which your profile said that your Dad had. Sadly said disease will sometimes make one tell some really wild off the wall untrue stories.

Scroll down to the bottom of this page to the blue panel, you will see "Alzheimer's Care", click on that and scroll down until you find an article about untrue stories. Print that out for your siblings to read.

My heartfelt sympathy to you and your family for the passing of your Dad.

Susan, if your dad has passed away there is no reason for you to try to defend yourself from these accusations. Go no contact with your brother, and if he assaults you again call the police and press charges, then get a restraining order.
