I have a stepbrother that is up to no good. My Dad has dimentia and his son from a previous marriage is constantly hitting him up for money and asking for large sums to pay for DUI's, invest in restaurant ventures, just crazy amounts of money, He has no problem asking my Dad for $400,000 any time he sees him. Because of the dimentia, my mom divorced my dad because she couldn't stand living like that. So, the money has been divided in half leaving my Dad with dwindling assets to live on and he has no income coming in because he's retired and all of his investments have turned out to be bad decisions. My evil stepbrother was in town over the weekend and was taking care of my Dad and gave him the wrong medications and my Dad was very confused. I feel like he may have even done it on purpose but my family thinks I'm being paranoid on that one. Everyone agrees that evil stepbrother is a freeloader and opportunist and criminal but not so sure on whether or not he is a murderer. However, he does drink drunk and have seizures on the road putting other people's lives in danger every day. This guy is bad news. Any ideas on how I can protect my Dad?
