Chad Daybell, Lori Vallow — parents of minors missing since Sept. — found in Hawaii

KAUAI, Hawaii (KSTU) -- The mother and stepfather of two missing minors from Idaho have been found in Kauai, Hawaii.

Chad Daybell and Lori Vallow have been in Kauai for an unconfirmed amount of time. The Kauai Police Department is assisting the Rexburg Police Department in Idaho in the case of two missing children: 17-year-old Tylee Ryan and 7-year-old Joshua "JJ" Vallow.

Vallow and Daybell were served with a legal document on Saturday ordering Lori Vallow to produce the children. On Sunday, police executed a search warrant, the Salt Lake Tribune reports.

Tylee and JJ have been missing since September 2019. Daybell and Vallow married shortly after Daybell's wife, Tammy, was found dead. Investigators initially suspected Tammy Daybell died of natural causes, but have since exhumed her body and categorized her death as suspicious. Vallow's husband was also found dead earlier last year.

Daybell and Vallow, who married two weeks after Tammy Daybell's death, have not cooperated with the investigation.
