My wife's abusive sister has their parents captive in their own home. She has obtained poa and a will but won't share with my wife. My wife cant even get medical info from the hospital when she goes to visit. Without ranting the whole story I'll bottom line it for discussion. We believe that the parents are being abused and starved. What can we do? Hire a lawyer? Investigator? Social worker? They have Alzheimer's but may have signed the house over to the sister...Best case would be to get the sister and her family out and get in home professional care for the two parents....are we too late?
