       Chad Daybell listens during his preliminary hearing, Aug. 4 2020, in St. Anthony, Idaho. Lori Vallow Daybell and Chad Daybell were each indicted by a grand jury on May 24, 2021, on charges of conspiracy, murder and grand theft in connection with the deaths of Lori Daybell's two youngest children, 7-year-old Joshua "JJ" Vallow and 17-year-old Tylee Ryan. Chad Daybell was also charged with one count of murder in connection with the death of his late wife, Tammy Daybell, just weeks before Lori and Chad married.

       Since then, authorities said Vallow and Daybell’s story has publicly unraveled and both face charges in connection to multiple murders.

       Daybell appeared in court Tuesday morning for a hearing on whether his trial should be moved from Fremont County to Ada County after the defense argued that the jury in Fremont County may be swayed by extensive media coverage in the area.
