Sorry for the typo. I meant " 'her' brother."
You need an attorney. If you cannot afford one, contact you state's bar association - they have attorneys who can help you for free or for a reduced fee.
Also, contact adult protective services and let them know what your brother did.
Here is the Idaho State Bar Assoc. website: http://www.isb.idaho.gov/ilf/ivlp/seeking_legal_assistance.html
good luck
