Family Vanished on Road Trip in 1998 - 20 Years Later a Drone Makes A Chilling Discovery… In August 1998, the Morrison family packed their car for what should have been a perfect week-long camping trip to Mammoth Cave, Kentucky. That was the last time anyone saw the Morrison family alive. Twenty years later, a land surveyor using a drone to map remote forest land in eastern Kentucky made a discovery that would change everything. Deep in the woods, hidden beneath decades of overgrowth, was a massive sinkhole. And at the bottom, a chaotic graveyard of hundreds of rusted, mangled cars stacked like broken toys. Including the Morrison family car that had been missing for two decades. What investigators found in that hidden automotive cemetery would expose a conspiracy so vast and cold-blooded, it had been operating in plain sight for over twenty years, turning family road trips into profitable murder schemes.
