REXBURG, Idaho (AP) — Authorities are searching for two children tied to a suspicious death case in Idaho. The Rexburg police department said 7-year-old Joshua Vallow and 17-year-old Tylee Ryan have not been seen since September. Rexburg police said the parents never reported the kids missing, have repeatedly lied about where their children are and aren’t cooperating with the investigation. Their mother, Lori Vallow, recently married Chad Daybell. Though police haven’t disclosed the exact nature of the connection, authorities note the new marriage happened shortly after Daybell’s first wife, Tammy Daybell, was found dead at home in October.
