Idaho mother Lori Vallow believed that her two children, seven-year-old JJ and 17-year-old Tylee, were possessed by evil spirits and had become 'zombies,' according documents recently filed in court in a relative's custody case.

The first husband of Vallow's niece, Melani Boudreaux Pawlowski, alleges in the records that Lori and her new husband, doomsday author Chad Daybell, espoused some unconventional beliefs about people turning into zombies and requiring help to rid of demons possessing them.

Vallow has been charged with two felony counts of desertion and nonsupport of dependent children, resisting or obstructing officers, criminal solicitation to commit a crime, contempt of court and willful disobedience of court process or order.

A court filing claims Lori Vallow believed her two children, seven-year-old JJ and 17-year-old Tylee, were possessed by evil spirits and had become 'zombies'

The FBI released this photo of the family at Yellowstone National Park on September 8 and has asked anyone with information about that day to come forward. Video from the family's trip has been turned out to Vallow's defense as part of discovery

Vallow's daughter was last seen on September 8 during a family trip to Yellowstone National Park. Her younger brother was last seen leaving school on September 23.

The mother was extradited earlier this month from Hawaii to Idaho, where she remains in jail on $1million bail. She is due back in court for a preliminary hearing on May 7.

As East Idaho News first reported last week, in court documents filed by Brandon Boudreaux, the former husband of Lori Vallow's niece, Melani, as part of a legal battle over the custody of their four young children, claims that his ex-wife knows where JJ and Tylee are, was part of her aunt's religious group, and played a role in an attempt on his life.

The revelations come from what Melani's second husband, Ian Pawlowski, told his lawyers. The filing does not specify how Boudreaux obtained the documents, but the website reported, citing unnamed sources, that it came from Pawlowski's computer.

According to the court records, Pawlowski has revealed that just days into his relationship with Melani, she discussed with him some of her unusual religious beliefs, which ran the gamut from teleportation to 'dark and light portals' and 'dark translated humans' who were the followers of Satan, Lucifer and Cain.

The conversation also covered the subject of zombies, which Melani allegedly explained were 'human bodies that have had their original spirits forced out of them' and possessed either by a demon, or a worm or slug.

Pawlowski wrote that at first he tried to keep an open mind about Melani's beliefs, some of which she said she had learned from her aunt Lori and her fifth husband, Chad Daybell.

Pawlowski stated that when he first met Lori and her new husband in person, he did not get a bad impression of them, but it struck him that some of their ideas about religion felt like they were 'ripped straight out of a Dungeons & Dragons manual.'

According to Pawlowski, Melani told him she feared that her first husband, Brandon, had been possessed by a demon, and that she had been told by Daybell and Lori that her children, Tylee and JJ, also had been possessed and had become zombies.

'She shared concerns that she’s been told Brandon needed to die and that may indicate that Tylee and JJ needed to die as well,' Ian allegedly wrote. 'She told me she was worried that [her brother Alex Cox] may have had to "take care" of the kids.

'She explained that [Cox] had great faith and never wavered in his trust in the Lord. No task would be too difficult or too great for him.'

The timeline of the mysterious deaths and disappearance in Vallow's immediate family

Cox, who was suspected of firing a shot at Brandon Boudreaux and narrowly missing him outside his home in Arizona in October, died under mysterious circumstances in December 2019, six months after he gunned down Lori's estranged fourth husband, Charles Vallow, during an argument. The brother claimed self-defense.

In another court document filed in February, Brandon Boudreaux stated: 'Melani is involved in a cult where numerous members, adults and children alike have been being killed off like flies.'

According to the filing, Melani's current husband, Pawlowski, whom she married on November 30, had told law enforcement that she 'says sometimes [her] children are full of light and then just like that they go dark'.

Melani Boudreaux Pawlowski has vehemently denied through her attorney her ex-husband's claims.

'Mrs. Pawlowski has cooperated with law enforcement, including meeting for hours with the FBI on three separate days. As she told the FBI, Melani does not know the whereabouts of the missing children of her aunt, Lori Vallow,' her lawyer Robert Jarvis said in a press release.

Weeks after her fourth husband Charles Vallow's death at the hands of her brother, Lori moved her children from Arizona to Idaho, where her soon-to-be husband Chad lived with his then-wife Tammy.

Tammy was found dead under mysterious circumstances on October 19.

The 49-year-old's death was initially ruled as natural causes but an investigation was opened after police learned about Chad's quick marriage to Lori while searching for her kids.

Tammy's body was exhumed on December 11 and the results of her autopsy have not yet been released.

In November, Vallow and Daybell fled to Hawaii, where she was arrested in February. Her husband is not facing any charges.
