The Ada County Coroner’s Office announced on Thursday that it had signed an agreement with the Fremont County Coroner’s office to provide pathology services on the remains of siblings Tylee Ryan and J.J. Vallow.

The children’s remains were found on Chad Daybell’s property earlier this month. The youth had been missing since September. In November, Daybell married the children’s mother, Lori Vallow-Daybell, two weeks after his first wife, Tammy Daybell, died under mysterious circumstances.

"Outside and ancillary testing have been ordered and will take several weeks to return. Once all results are received, the Forensic Pathologist’s reports will be provided to the Fremont County Coroner,” stated the press release.

Brenda Dye serves as the Fremont County Coroner, and took the children’s remains to Boise shortly after they were discovered. The children had been buried in the Daybell’s pet cemetery and were located after police followed the cell phone “pings” of their uncle the late Alex Cox who had visited the Daybell property on several occasions in September.

On September 8, the children, Cox and Vallow-Daybell visited Yellowstone National Park. Tylee wasn’t seen again, but J.J. was last seen on a neighbor’s camera on September 17.

Chad Daybell was arrested on June 9 shortly after police discovered the remains. The state is charging him with two felony counts. The first maintains that on or between Sept. 22, 2019 and June 9, 2020, Daybell concealed human remains knowing that those remains would be used as evidence in a felony proceeding. In the second count, the state alleges that Daybell on Sept 8, 2019 and June 9, 2020 willfully destroyed, altered or concealed remains with another knowing the remains were about to be produced for a felony proceeding. 

Daybell is being held on a $1 million bond and is scheduled for a preliminary hearing in August in the Fremont County Courthouse. His wife is being held at the Madison County Jail also on a $1 million bond.

The state is charging Vallow-Daybell with two felony counts of desertion and nonsupport of dependent children as well as misdemeanors involving resisting or obstructing officers, criminal solicitation to commit a crime, and contempt of court. Her preliminary hearing is scheduled for July 9 and July 10 at the Madison Courthouse.

The couple also faces potential conspiracy, attempted murder and murder charges in Tammy's death. An autopsy was performed on Tammy's body in December the results of which haven't been released.

The Vallow, Daybell and Ryan families have suffered from several deaths in recent years. In 2018, Tylee's father and Lori's third husband, Joseph Ryan, died of what was initially deemed a heart attack. As his body was cremated no autopsy was done. In July 2019, J.J.'s adoptive father and Lori's fourth husband, Charles Vallow, was shot and killed by Cox in an alleged domestic violence incident. Tammy died in October, and Cox died of a blood clot in December. Now the three families are dealing with J.J.’s and Tylee’s deaths  believed to have taken place in September 2019.
