Investigators in Idaho have recovered human remains in an investigation connected to the search for two missing children with ties to Arizona.
Police in Rexburg, Idaho, confirmed Wednesday, "after proper family notification, we would like to confirm at this time that investigators have discovered two sets of unidentified human remains. Autopsy results are pending."
East Idaho News reports Chad Daybell's car was stopped about a mile from his Fremont County home and police took Daybell into custody. Daybell appeared in court Wednesday after a criminal complaint was filed alleging that Daybell took part in “destruction, alteration or concealment of evidence." A judge set bail at $1 million for Daybell.
The prosecutor in the Chad Daybell case stated that "they were aware" that the human remains discovered on Chad's property were that of children, but acknowledged that these remains have not yet been identified.
According to a news release from the Rexburg Police Department, its officers, with the assistance of the FBI and the Fremont County Sheriff’s Office, served the search warrant on Daybell's property around 7 a.m. Tuesday morning.
FBI Public Affairs Specialist for the Salt Lake office, Sandra Barker, confirmed that the FBI is assisting with the search warrant. She told CourtTV there were about 20 FBI personnel on scene helping, including agents and support staff.
Members of the FBI’s evidence response team were also at the scene. Barker could not give any details on exactly what prompted the search or what specific activities the FBI personnel were doing at the scene.
The search is connected to the case of Lori Vallow Daybell's missing children, Joshua "JJ" Vallow, 7, and Tylee Ryan, 17.
The warrant is sealed, meaning that the information is only available to law enforcement officers working on this case.
Numerous roads around the home were closed and drivers were re-routed.
Chad and Lori Vallow Daybell were found living in Hawaii in January. Kaua'i police and Rexburg police served search warrants there on January 25.
Lori Vallow Daybell was arrested on February 20, and has been in an Idaho jail ever since, despite several attempts to lower her bail.
Chad Daybell married Lori Vallow not long after his wife, Tammy, died of reported natural causes. The Idaho Attorney General is investigating possible murder and conspiracy in her death.
Authorities in Arizona had also been investigating two deaths tied to the case -- Lori Vallow Daybell's fourth husband, Charles Vallow, as well as her brother, Alex Cox.
Cox had shot and killed Charles Vallow during an altercation at Lori Vallow Daybell's Chandler home in July 2019. Cox claimed the shooting was in self defense, and charges were never filed against him. Investigators have previously told ABC15 they would like to speak with Lori Vallow Daybell again about the July incident.
About six months after that shooting, on Dec. 11, 2019, Cox was found unresponsive in his Gilbert home and was later pronounced dead, according to Gilbert police.
Officials had been investigating the circumstances around Cox's death for several months. A medical examiner's report released in early May indicated he died due to a pulmonary embolism.
