KSL TV CHANDLER, Arizona — Over 2,500 pages of information — primarily emails — has been released from Arizona investigators sharing new details into the investigation of Chad and Lori Daybell. The couple was indicted by a Fremont County grand jury in Idaho in May on charges including first-degree murder in the deaths of Tammy Daybell, Chad's previous wife, and Lori's two kids, 7-year-old Joshua "JJ" Vallow and 16-year-old Tylee Ryan. The couple is also facing charges concerning the destruction, alteration and concealment of the children's bodies. In Arizona, Lori is facing a felony conspiracy to commit murder charge in connection to the death of her husband, Charles Vallow. Lori's now-dead brother, Alex Cox, shot and killed Charles in July 2019. Cox called the shooting self-defense, but investigators say evidence tells a different story.
