Brian Shaffer spent the evening of March 31, 2006 with friends before arriving at the Ugly Tuna Saloona in Columbus, Ohio. Several people interacted with him during the night, including friends and two women captured on surveillance footage shortly before he disappeared. Yet none of those encounters has explained what happened next.

In this episode of Unsolved and Missing, we examine Brian's final known interactions, what investigators learned from the witnesses, and why the people closest to the timeline could not solve the mystery.

Sometimes the last people to see someone alive know only as much as everyone else.
