Chad Daybell is charged with the deaths of his wife Tammy Daybell, and his current wife Lori Vallow Daybell's two youngest children. Trial is set to begin in Idaho this Weds, April 10, 2024.

Chad Daybell’s trial is expected to last up to 10 weeks.

The 55-year-old self-published author is charged with three counts of first-degree murder for the deaths of Tammy Daybell, 7-year-old Joshua “JJ” Vallow and JJ’s big sister, Tylee Ryan, who was last seen a few days before her 17th birthday.

Lori Vallow Daybell sentenced to life in prison after being convicted of killing two of her kids.

Lori Vallow Daybell — who married Chad Daybell shortly after the deaths — was found guilty last year and sentenced to life in prison without parole.

The couple claimed they could tell if people had been possessed by dark spirits that could turn them into “zombies,” former friend Melanie Gibb testified in court. They believed the only way to get rid of a zombie was to destroy the possessed person’s body by killing them.

The children’s bodies were found buried in Chad Daybell’s eastern Idaho yard in the summer of 2020.

Chad Daybell also is charged with insurance fraud in connection with Tammy Daybell’s death and two counts of conspiracy to commit first-degree murder and grand theft by deception in the children’s deaths.

If convicted, he could face the death penalty.
