THE FOLLOWING IS ALL IN MY OPINION ONLY *****
The thing is, it's confusing --- PF wanted people to believe that KB had taken off and gone north. But... he also wanted it to look like a robbery gone bad and she was killed in her home. You can't have it both ways. It doesn't make sense.
Another contributing factor was KB's grandmother being ill in WA.
Maybe KB expressed to PF that she wanted to move back to WA with Baby Girl. Or PF knew KB wanted to visit her grandmother and was afraid that once back in WA, she would want to move back there.
This case reminds me more and more of CW's case.
1. Financial stress
A. PF probably didn't make that much money as a farrier. People knew him to abuse animals.
B. Cattle price were down
C. He's getting older and having to compete with guys in the teens or early 20s in the rodeo competitions
D. After buying the townhouse, KB may have ased that PF start paying child support
2. Custody
A. PF didn't want another man raising hs child
B. PF wanted Baby Girl for the sake of his mother who had lived alone w/PF for 20 years
C. PF would want to block any efforts of KB to move away w/ Baby Girl
D. If KB were dead, he would control Baby Girl and her inheritance + insurance payouts
3. Sexin'
A. PF Didn't want to give up his cozying up w/ rodeo girls
B. His sex life w/ KK may have been very different than KB
4. Don't tell me what to do!
A. PF was sick of answering to his mother about everything
B. PF didn't want to deal w/ KB making demands on him
5. Dads
Where are the dads of PF and KB? It is unusual not to hear from either of them
IMO **** MOO
