It’s hard to comprehend what goes on in the mind of someone who would commit murder, but as several here have suggested, it seems like it may be about control. The old adage “I don’t want you, but I don’t want anyone else to have you either” comes to mind. It’s impossible to see how anyone could kill the mother of their child if they love that child, but a sociopath/narcissist doesn’t really love anyone else IMHO. Their minds are so warped that they will commit acts we can’t understand, like so many other cases we’ve followed here, too numerous to mention. I’m not going to venture a guess as to how or why, but I am very anxious to see this case unfold to see the extent of PF’s evil scheme. I pray that he gets what he deserves. No family should have to endure that.
