Some of the most disturbing cases aren’t defined by mystery…they’re defined by warning.

This week on Nerdery & Murdery, Zig dives into Advanced Dungeons & Dragons, exploring the game that shaped modern tabletop roleplaying and inspired generations of players long before RPGs went mainstream.

Then in the Murdery, we continue our A–Z journey across America’s serial killers, arriving at Colorado; not as the site of a final crime, but as a critical point of failure.

This episode examines the life and crimes of Joseph Edward Duncan III, a man repeatedly identified as dangerous, repeatedly supervised, and repeatedly allowed to move on. Colorado was one of the last places where intervention could have stopped what came next.

This isn’t a story about the unknown.
It’s a story about documented risk…and delayed action.
