Crime Missing Idaho Kids' Grandparents 'Holding Out Hope' Kids Are OK, Say Mom 'Should Be in Handcuffs' More than five months after J.J. Vallow and Tylee Ryan were last seen alive, their extended family still hopes for good news By Steve Helling Published on February 19, 2020 08:00 AM Share Tweet Pin Email Joshua “J.J.” Vallow, at left, and his sister Tylee Ryan. The grandparents of two missing Idaho kids are speaking out, telling PEOPLE they’re holding out hope the siblings will return safely. But they also have harsh words for the mom of the siblings, who has refused to cooperate with the police investigation into their disappearance. The two siblings — Joshua “J.J.” Vallow, 7, and Tylee Ryan, 17 — were last seen in September, according to the Rexburg Police Department. Their mother, Lori Vallow had recently married Chad Daybell, a religious author who writes about prophecy and the end of the world. Nothing is known about the kids’ whereabouts — or even if they’re alive or dead. But in this week’s issue of PEOPLE, J.J.’s paternal grandparents say that they’re “holding out hope” the kids are alive. “There are two phone calls I want to get right now,” says Larry Woodcock, the boy’s grandfather. “The first call is that they’ve been found right now. J.J. and Tylee are safe and they’re heading home. And the second call is that Lori and Chad Daybell have been arrested.” Mom of 2 Missing Idaho Kids — Who Refuses to Cooperate — Allegedly Believes She’s God Reincarnated Joshua “J.J.” Vallow, at left, and Tylee Ryan.
