If women kill their children to hold on to a man, would a man kill a fiance to hold on to another woman? I keep thinking something happened this past fall that was the straw, something that was worth soliciting someone for murder and planning out Kelsey's murder. It's hard to pin down a motive because so many times it's quick, done out of rage and anger, but this was carefully and soberly planned. Could KK have told him that he had to make a choice and he was too afraid to tell KB to get lost? I mean in his previous relations he cheated rather than ending things, that shows a desire to avoid confrontation. Doesn't it sound like he was cheating on KB with KK? Why not just say "hey KB, I've met someone else and I'm moving on", but that doesn't seem to be the case. Instead KB is still engaged, things are moving forward from her perspective and the only one who's talking about "break ups" is PF, at least that's what KB's family have said. But what happened in late summer or Aug that made him decide to kill her?
There is a chance that KK had also been told that PF and KB had ended things. Maybe KK wanted to move down and be closer, live on the farm, bring her kids.
