SALEM, Idaho — Chad Daybell is due in court for his initial appearance Wednesday after investigators recovered what they believe are human remains on his property.
East Idaho News reports Daybell was arrested for destruction or concealment of evidence Tuesday. He has been booked into jail in Fremont County, and his initial court appearance is scheduled for 11 a.m. Watch FOX 13 for live coverage.
Police and FBI agents served a search warrant at Daybell's home in Salem, Idaho Tuesday morning in connection with the search for two missing children — his stepson Joshua "JJ" Vallow and stepdaughter Tylee Ryan.
Police took Daybell into custody about a mile from his home as numerous police officers and FBI agents served the search warrant.
Authorities later announced that human remains were recovered. They have not yet been identified.
He was booked into the Fremont County Jail several hours later. Specific charges were not disclosed, but authorities did say they were felony charges and that he was being held with no bond.
He is scheduled to appear in court Wednesday at 11 a.m.
"We saw a car fly past us, a silver car, and a bunch of cops behind him. They ended up circling him and getting him to pull over. And then we turned around and went back and Chad Daybell was getting arrested," said Brittany Chapple, who was in a car on Salem Highway at the time Daybell was taken into custody.
Chapple said she recognized Daybell from news coverage about the disappearances of the two kids, and because she lives a few miles from Daybell's residence.
"My son thinks that he saw [Daybell] on the ground when they were arresting him, and then, when we flipped back around, he was standing up and he was handcuffed," Chapple added.
Sandra Barker, FBI Public Affairs Specialist for the Salt Lake office, has confirmed that the FBI is assisting with the search warrant.
She told CourtTV there are about 20 FBI personnel on scene helping, including agents and support staff.
Members of the FBI’s evidence response team are at the scene. Barker could not give any details on exactly what prompted the search or what specific activities the FBI personnel are doing at the scene.
Aerial footage appeared to show investigators digging in a specific area of a field adjacent to Daybell's house.
The warrant is sealed, meaning that the information is only available to law enforcement officers working on this case.
Numerous roads around the home are closed and drivers are being re-routed.
Chad Daybell's wife, Lori Daybell, (formerly Vallow) was arrested in February and charged with two felony counts of desertion and nonsupport of dependent children. She has been in the Madison County jail ever since, despite several attempts to lower her bail.
The two children were reported missing after JJ's grandparents told police they could not get in contact with him. They were last seen in September. Tylee and JJ were 17 and 7, respectively, at the time of their disappearance. JJ's 8th birthday was last month.
The couple was found living in Hawaii in January. Kaua'i Police and Rexburg Police served search warrants there on January 25.
The two were married not long after Chad's wife, Tammy, died of reported natural causes in October. The Idaho Attorney General is investigating possible murder and conspiracy in her death.
Lori's former husband, Charles Vallow, also died shortly before the newlywed couple were married. He was shot by Lori's brother Alex Cox — who died in December of a heart attack — who claimed self defense. Lori and Charles were reportedly in a domestic dispute, and Alex and Lori claimed that Charles wielded a baseball bat and hit Alex with it when he got involved.
Police served a search warrant earlier this year at Chad's Salem home, but no information was released on findings.
