I wonder about that too. Not at all implying his mother had anything to do with the actual crime, but as time was rolling on and nothing was moving forward, PF may have expressed his discontent with the relationship, bad mouthing KB to his mother and family (most likely due to his own feeling of inadequacy), in that she was pressuring him, questioning him regarding his intentions with getting married and such. Of course, his mother would bring up, "what will happen if you leave her? She may go back to WA. We'll never see the baby" I'm sure as others here have pointed out, Kelsey was having serious doubts herself even if she still considered herself "engaged" to be married. In my gut, I still have this gnawing feeling that PF had already moved on to someone else, even if he hadn't actually met face to face with someone. I suspect he was already trolling on a dating site. JMT
