PF is the person who does not understand how the technology works. The phone part of it he messed up totally. Yet he very well knows how to hide the body, because he is the farmer, the hunter, and lives on this land. He did well with that part.
Much as if it came to the phones, i’d ask Verizon, AT@T or T-Mobile rep, to understand how to hide the body, one has to talk to a person like him, a farmer, a local, maybe a dog breeder, a cowboy. But mostly, a local. Just to understand the pattern of thinking behind it.
I feel that the LE is handling KK very nicely, and that they are handling PF’s family nicely. I understand that they are relatives, but they are in the LE system, and a heinous crime has been committed. Essentially, their brother is the true criminal, a murderer. There could have been ways to talk to his family to make PF more cooperative. My feeling is, PF is probably a sick, paranoid, angry man, but if he cares about anyone, it is his family.
