I have been home taking care of my Father for a year and I am uncovering, either by conversation or documentaion, where my Father has been taken advantage of by a family.  I suspected this for years, but could not convince him to get out of the situation until August of last year.  He now resides with me.  I suspect in addition to several trips to the bank, he has been taken for approximately for $450,000 for an 'investment", but no documentation uncovered, yet.  Is there anything I can do?
