Vallow Daybell tells veteran host Keith Morrison on the episode of "Dateline" airing on March 7 that she believes she and her husband, Chad Daybell, are innocent of the crimes. “I will be exonerated," she said in an excerpt of the show. "We will both be exonerated in the future.”

Lori Vallow Daybell tried to shift blame for her son's death to her slain daughter, 16-year-old Tylee Ryan, while talking to Dateline correspondent Keith Morrison for an explosive new interview.

The interview took place at a jail in Maricopa County and detailed the months leading up to the murders of Vallow Daybell's children, Tylee and JJ.
