Deorr Kunz Jr., 2 years old at the time, was reported missing by his parents on July 10, 2015. The toddler’s parents, Jessica Mitchell and DeOrr Kunz, Sr., told authorities they believed DeOrr’s great-grandfather was watching him at the Timber Creek Campgrounds outside remote Leadore, Idaho, while his great-grandfather believed the boy was down by the creek with his parents and the fourth adult on the trip, a friend of the great-grandfather.

The parents’ separate 911 calls triggered an investigation that’s left more questions than answers. Discrepancies quickly emerged in the accounts of the circumstances under which Deorr vanished. Inconsistencies in statements from the tot’s parents became public; officials say both have failed multiple polygraph tests. Both Mitchell and Deorr Sr. were named suspects in the case in January.
