In the fall of 2019, the close-knit, religious town of Rexburg, Idaho — dubbed "America's Family Community" — was stunned by the disappearance of 16-year-old Tylee Ryan and 7-year-old Joshua "J.J." Vallow.
The two had last been seen alive that September, and as authorities opened an investigation into the missing children, they began looking at their mother, Lori Vallow, and her new husband and doomsday author, Chad Daybell, in hopes of finding answers.
As of yet, no one has been charged for Tylee and J.J.’s murders, and the investigation is ongoing.
The case will be featured in the season two premiere of "Injustice with Nancy Grace," airing Thursday, October 8 at 9 p.m. ET/PT on Oxygen. As television's most respected legal analyst and victims’ rights advocate, Grace brings her unique perspective to some of the most complex and current true crime stories, shining a light on investigative and legal injustices.
Before tuning in, get up to speed on the investigation with the timeline below.
Divorced mother Lori (sometimes referred to as Lori Daybell or Lori Vallow Daybell) marries her fourth husband, Charles Vallow. At the time, Lori had two children from previous relationships: her eldest son, Colby Ryan, and daughter, Tylee Ryan.
Lori and Charles adopt J.J. Vallow, the grandchild of Charles' sister, Kay Woodcock.
