A satellite image appears to have captured the freshly-dug grave of an Idaho teen who was found burned and buried in her stepfather’s backyard.

KSL-TV obtained satellite images taken of Chad Daybell’s home outside of Rexburg on September 9, 2019, the day that investigators traced Tylee Ryan’s uncle to his brother-in-law’s property using cell phone pings, according to an arrest affidavit obtained by CrimeOnline.

Tylee Ryan, 17, and her 7-year-old brother JJ Vallow were both found dead in Daybell’s yard on June 9 — and the bodies had likely been there since September, the last time both children were seen alive.

The children’s mother Lori Vallow is in custody in Madison County awaiting trial on felony desertion charges, and Daybell is being held on charges of obstruction or concealment. A prosecutor indicated at Daybell’s preliminary hearing that more charges could be expected.

Using cell phone data, investigators believe they traced Lori Vallow’s brother Alex Cox to the Daybell property on the mornings of September 9 and September 23, the day after each of the children were last seen alive. The affidavit appears to show that JJ Vallow was found buried in a tightly-wrapped plastic bag, and Tylee Ryan’s remains were burned.

Alex Cox died suddenly in December. After an investigation that spanned several months, a medical examiner determined that he died of a pulmonary embolism.

According to the KSL-TV report, a satellite system called Pléiades 1 captured images on September 9, 2019 that appear to show disturbed ground in Daybell’s backyard in the area where investigators were seen digging on June 9. Pléiades 1 is reportedly a satellite system created by the aerospace company Airbus that routinely takes images of the earth’s surface for unspecified scientific research purposes.
