"48 HOURS" GOES INSIDE THE INVESTIGATION TO FIND TWO MISSING CHILDREN IN "THE FINAL DAYS OF JJ AND TYLEE"

Saturday, Oct. 3

CBS News correspondent Jonathan Vigliotti and 48 HOURS take viewers inside the investigation into the heartbreaking national search for two missing children in "The Final Days of JJ and Tylee" to be broadcast Saturday, Oct. 3 (10:00 PM, ET/PT) on the CBS Television Network.

The search for the two children captured the nation and made international headlines. In this broadcast, viewers will hear the inside story of what led police to find the children's remains.

Police say the children disappeared in September 2019, shortly after the family moved to Rexburg, Idaho, from Arizona. Investigators say Tylee was last seen in Yellowstone National Park with her family on Sept. 8. Investigators say JJ vanished on Sept. 22. For six months, their mother, Lori Vallow, and her new husband, Chad Daybell, refused to say where the kids were. Then, last June, police found their bodies buried in Daybell's backyard.

"I just always had that hope that they were alive, and so when I heard the news, I was just, like, so dumbfounded because ... I just completely believed they were alive," says Vaisia Itaaehau, one of Tylee's best friends.

In the hour, 48 HOURS details the investigation, the life of Lori Vallow and what is ahead in the case against Vallow and Daybell, on charges of conspiring to destroy, alter or conceal evidence. 48 HOURS: "The Final Days of JJ and Tylee" is produced by Liza Finley and Richard Fetzer.
