Chad Daybell, husband of “cult mom” Lori Vallow, is set to stand trial in Idaho this week for the murders of his wife’s two children and his first wife in 2019.

The pair is at the center of multiple murder cases involving not only Vallow’s two children but both her and Chad’s deceased ex-spouses. They were initially scheduled to have a joint trial, but Chad’s defense attorneys got a separate trial for the self-published author in 2022, citing “mutually antagonistic defenses” between the two cases.

“Our version of the facts of this case will differ greatly from what Ms. Vallow and her legal counsel are going to be presenting,” said John Prior, Daybell’s attorney, during a Nov. 10, 2022, court proceeding.

An Idaho jury in May 2023 found Vallow, 50, guilty on multiple counts, including two counts of first-degree murder, for the 2019 disappearances and deaths of 7-year-old J.J. Vallow and 16-year-old Tylee Ryan, allegedly with help from her husband. Vallow also conspired to kill Tammy Daybell, Chad’s first wife, in October 2019.

“You removed your children from their home in Arizona, alienated them from friends and family … and you brought them here to murder them. You had so many other options. … You chose the most evil and destructive path possible,” Judge Steven Boyce said during Vallow’s sentencing hearing. “I don’t think to this day you have any remorse for the effort and heartache you caused.”

Officials extradited Vallow to Arizona, where she faces one first-degree murder charge and one premeditated first-degree murder charge in Maricopa County, in November 2023.
