On the debate of who is the mastermind: if I have followed correctly Lori was a fan/groupie of Chad's. Have read there was a change in her personality. Did she meet or start conversing with Chad prior to the death of Mr Ryan? Chad's brother stated of the distance between their families due to Chad's works and views. I am sure from LEs confiscation of electronic devices the correspondence between the two will reveal who was planting seeds and who was following whose suggestions. Were Lori's family members, who are marrying off and dying, also fans of Chad's?
Finally, who had the "visions" of Tammy's death first? It is likely that JR is riding a publicity wave, but I hope LE is following up with everyone involved in this tangled web. I would think public statements of invisioning the death of a healthy 49 year old, possible homicide victim, would peak some interest.
