There’s a certain kind of killer and Amy Fitzgerald was the victim of one of them. Maybe not as famous as some of the others — Scott Peterson, Chris Watts, Charles Stuart, Mark Hacking, the list goes on and on — but her story is just as significant as their victims. Marilee Strong identified these type of men in her 2008 book “Eraser Killers,” and we’ll talk more about how very dangerous they are, particularly since people still don’t get it. Maureen also has the latest Maura Murray update, Rebecca does an NNW review of the Netflix documentary “The Puppet Master,” and our ongoing discussion of “Dalgleish” continues.
