Lori Vallow News: Investigators To Search Yellowstone National Park For Missing Idaho Siblings

Investigators plan to search Yellowstone National Park for Tylee Ryan, 17, one of the two missing siblings from Idaho. Tylee Ryan and her 7-year-old brother Joshua Vallow, are the children of Lori Vallow, 46, who was arrested Thursday in Hawaii on two felony counts of desertion and nonsupport of dependent children, resisting or obstructing officers, contempt of court and criminal solicitation to commit a crime.

Investigators are reportedly waiting for the snow to melt to improve search efforts, sources told CBS News.

Court documents said phone records showed Tylee had visited Yellowstone on Sept. 8, 2019 — about two weeks before Joshua was reportedly last seen. They are believed to have visited the national park with Lori Vallow and Lori Vallow's brother, Alexander Cox. Police reportedly found a photo on Lori Vallow’s personal iCloud account showing Tylee at the park.

The report comes after Lori's Vallow's niece, Melani Pawlowski, was accused by her ex-husband, Brandon Boudreaux, of knowing about the children's whereabouts. Boudreaux made the accusation during a custody battle in Gilbert, Arizona.

“Melani's knowledge of the whereabouts of her aunt's two missing children and her unwillingness to cooperate with law enforcement is daunting and her current husband has told law enforcement that Melani says sometimes children are full of light and then just like that they go dark,” Boudreaux said.

FOX 10 Phoenix obtained court documents that also stated Pawlowski's current husband "listened to her confess that she conspired to kill Brandon at his home" and that Cox was the shooter. In July, Cox told police that he shot Charles Vallow, Lori Vallow’s estranged husband, in self-defense at her home in Chandler, Arizona. On Dec. 12, Cox was found dead in the bathroom of a home in Gilbert.

Boudreaux was shot in October while pulling into his home. He said that shots came from a rifle with a silencer from a 2018 Jeep Wrangler with Texas license plates that was parked in front of his home.

“Brandon believed Melani, his wife at the time, had a million dollars of reasons to have him killed ... hoping to cash in on the policy to help support the cult that she is believed to be a part of,” court documents said.

The cult is reportedly the same doomsday cult that allegedly includes Lori Vallow and her husband Chad Daybell.
