Lori Vallow Update: Mother Believed Tylee, JJ Were 'Zombies,' Ex-Best Friend Claims

Lori Vallow believed her children were zombies and she wanted to rid the world of such creatures, new court documents revealed as part of a bizarre twist in the case. Vallow and her new husband, Chad Daybell, faced quite a bit of suspicion following the disappearance of her children.

The remains of 17-year-old Tylee Ryan and her 7-year-old brother, Joshua "JJ" Vallow - who were missing for months - were found on June 9 at a property belonging to their mother's new husband.

Vallow's longtime best friend, Melanie Gibb, who has been cooperating with authorities for months revealed some details, shedding light into the case, according to the documents written by Rexburg police Lt. Ron Ball.

"Gibb reports that when she arrived in Rexburg, Lori Vallow informed her that JJ Vallow had become a 'zombie,'" Ball reportedly wrote. "Gibb further reports that the term 'zombie' refers to an individual whose mortal spirit has left their body and that their body is now the host of another spirit. The new spirit in a 'zombie' is always considered a 'dark spirit.'"

Gibb is the last known person to have seen JJ alive, according to police, when she was visiting Vallow at her apartment in the small Idaho town of Boise last September.

Gibb said she heard her friend talk about zombies earlier as well. According to the statement, Vallow had called Tylee a zombie in spring 2019 when the teenager didn't want to babysit her brother. Gibb added that Vallow and Daybell believed that when a zombie takes over a person's body, "the person's true spirit goes into 'limbo' and is stuck there until the host body is physically killed," the court document said. "As such, death of the physical body is seen as the mechanism by which the body's original spirit can be released from limbo."

"She [Gibb] was told by Chad Daybell and Lori Vallow that they held the religious belief that they were a part of the 'Church of the Firstborn' and that their mission in that Church was to lead the '144,000' mentioned in the Book of Revelation. They also stated their mission was to rid the world of 'zombies,'" according to the police document.

The case of two kids, who disappeared in September, gained attention for the couple's doomsday beliefs and the mysterious deaths of their former spouses.

So far, no one has been charged with killing the kids but both, Vallow and Daybell, are behind bars. Daybell has been charged with two counts of destruction and alteration or concealment of evidence, which are felony charges. Daybell pleaded not guilty to destroying or concealing the children's bodies.
