After Alex tried kill her with a spear gun Marion asked for a

Divorce

A Hearing was held

I strongly believe that it is necessary to warn the unwary but likely victims of psychopaths of the danger they face.  Alex was able to evade accountability for his actions mostly because he was the heir to a dukedom.   But other psychopaths have done the same, some with nothing in particular either in family background, profession, looks, or cunning, to evade accountability.

Most often, as you see with Marion, victims flee.  For his second victim, Wendy Buford, having had two children with him this was not as easy, but after this last rather long attack by Alex and the group, who with him, were paid generously to attack both Wendy and myself, Melinda Pillsbury-Foster, both Alex and his third wife, Laura Smith, were freeded from the need to live in fear.  
The surmise is that Alex's activities  criminal activities, reported by the victims there, finally caught up with him, to which Wendy and I breathed a sigh of relief.  

Laura is still using the title and, we understand, is still living in Las Vegas.
