For decades, ranchers across southern Colorado have awakened to a nightmare: cattle found dead under impossible circumstances — surgically precise incisions, organs removed, and almost no blood left behind. Rumors spread from lonely highways to isolated ranchlands: UFOs, cults, government experiments, predators… or something even stranger.

In this episode of Seven Deadly Sinners, retired police officer Greg Feinman comes to our ranch in Southern Colorado to tell us what he witnessed firsthand while investigating one of the West’s most chilling mysteries. From bizarre crime scenes to frightened ranchers and unexplained evidence, Feinman shares a case that still haunts him.

Were these mutilations elaborate hoaxes, covert operations, or phenomena beyond explanation? The deeper we dig into southern Colorado’s dark open plains, the stranger the story becomes.
