I wish we had answers to everything. I know it's not any of our business, but I can't help but wonder where the son was that night (the one living on the farm). No, I don't suspect him. I'm just curious as to why PM killed all who were living on the property except for the son. Also, is that the same son that had gotten married a couple years ago? I wonder if he's still married, or if they separated and that would be the reason for him living on the farm. The only answer I can think of is that PM was not only not of sound mind, but that he may have been financially in trouble. Then, I could see where he might have felt hopeless... if he'd only killed himself, that would've left his wife, Katrina and the kids struggling. If that were the case, maybe he believed all were better off dead. So sad if that's what happened. So sad regardless of the reasons.
