Besides the missing children, the couple has been under scrutiny following the deaths of both of their former spouses.
The complicated case began last summer, when Lori Daybell's brother shot and killed her estranged husband, in Phoenix. He claimed the shooting was in self-defense. The husband had filed for divorce, claiming Lori believed she had become a god-like figure who was responsible for ushering in the biblical end times. Her brother died of an apparent blood clot in his lung.
Shortly after, Lori and her children moved to Idaho, where Chad Daybell lived. He ran a small publishing company, where he published many of his own fiction books that centered on apocalyptic scenarios loosely based on Mormon theology. He also participated in podcasts about preparing for biblical end times, and friends said he claimed to be able to receive visions from "beyond the veil."
Police began investigating the children's [Tylee and JJ] whereabouts after relatives raised concerns. Investigators found the bodies of the two children buried in the back yard.
Tylee was last seen in September headed into Yellowstone National Park with her mom and other family for a day trip, and JJ was last seen by school officials several days later.
Can the "on-coming visions" be a helping hand?
