REXBURG — The Rexburg Police Department released photos Saturday afternoon of the mother and stepfather of two children who have been missing and are believed to be in serious danger.

Lori Vallow is the mother of 7-year-old Joshua Vallow and 17-year-old Tylee Ryan. Vallow recently married Chad Daybell and both are now considered “persons of interest” in connection to the disappearance of the children, according to Rexburg Police Capt. Gary Hagen.

Joshua and Tylee have not been seen since September and investigators want to speak with Vallow and Daybell. The parents are no longer communicating with law enforcement.

“They (originally) told us several stories about where the children are, but when we investigate, the children don’t exist where they say they should,” Rexburg Police Chief Shane Turman told EastIdahoNews.com Friday. “We don’t know where they are at, but we think they are in pretty serious danger.”

Joshua is a 7-year-old with brown hair and brown eyes. He is 4 feet tall and weighs 50 pounds. Tylee is a 17-year-old with blonde hair and blue eyes. She is 5 feet tall and weighs 160 pounds.

Anyone with information on the whereabouts of the children or Vallow and Daybell is asking to call the Rexburg Police Department at (208) 359-3000.
