If you get a chance, try to find "Master Manipulators" Season 3, Episode 43, on the OWN channel. Excellent story line.
Has to do with a widow, Mary Ellen Bendtsen of Dallas, who owned a very expensive house, who had befriended two antique dealers, and right after she had a stroke at 88 and while in the hospital, the antique dealers had an Attorney come to the hospital and have the widow change her Will. Thus her only child no longer would get the house, instead it would go to the two antique dealers. This changing of the Will was video taped so the Attorney could prove later on that Mary Ellen was of sound mind. She wasn't.

This is something that every one of us who have elders who own a home or have large bank accounts should take note. The above antique dealers befriended Mary Ellen to a point where she trusted them over her own daughter. I can't recall if the daughter had lived out of state or not. These two fellows had done this before with other elders they befriended, where in those Wills money was left to them.
