In an episode preview, those who knew Lori and Chad shed new light on the case as they share firsthand accounts of their interactions with the couple. According to one interviewee, Chad, at one time, not only believed that his wife had been "inhabited by a zombie," but claimed that you could also become possessed by either "a fallen spirit or a disembodied spirit." As stated in the preview, this is a belief that Lori supposedly shared as well.

Others reveal that Lori thought of herself as "a god" and a "translated being." Furthermore, some have stated that leading up to JJ and Tylee's disappearance, their mother had allegedly said that she believed they had become possessed and that they "needed to die."

However, others who knew the Idaho resident will also be highlighted in the new episode as they counter the narrative that has followed the case since the beginning. As seen in the clip below, there are some who believe that hype that has surrounded the case and the accusations of a cult's existence are not factual.

In a voiceover, Morrison states that on Friday night, those closest to "the most notorious mom in America" will share their true thoughts about her. As seen in the clip below, the new "Dateline" episode will also feature Lori's return after being "hauled halfway around the world in handcuffs to face the charges against her."

The episode will serve as a follow-up to the initial examination of Lori, Chad, JJ, and Tylee that originally aired in February. According to the NBC host, so much has happened since then that has made the unusual case even stranger. Those who tune in to watch this week's episode will get to find out the additional information that has been uncovered in the meantime.

This two-hour episode of "Dateline" will air Friday at 9 p.m. EDT on NBC.
