It was the night that changed everything. A devastating fire in a rural home in Tennessee resulted in the death of the children's grandparents, but there was no trace of Chloie or Christopher's remains. The event which sparked the longest running Amber alert in Tennessee history continues to draw questions, and TBI is no closer to solving the mystery of their disappearance. Did they run off into the woods, was kidnapping or foul play involved, or did the fire destroy the children's remains? We take a look at the prevailing theories and question what outcomes seem most likely based on anecdotal and forensic evidence.
