On the night of March 31, 2006, Brian Shaffer, a 27 year old Ohio State medical student, went out in Columbus to kick off spring break. He'd had a brutal month. His mom had died of cancer just three weeks earlier. But he was still going to class, and in two days he was flying to Miami with his girlfriend. He had dinner with his dad that night. Then he and a friend hit the bars. Just after 1 a.m., security cameras caught Brian riding an escalator up into the Ugly Tuna Saloona, a packed second floor bar near campus. Around 1:55 a.m., the cameras caught him again, just outside the entrance, chatting with two young women. Then he walked out of frame, back toward the bar. That is the last time anyone has ever seen Brian Shaffer. The cameras never recorded him leaving. Not on the escalator. Not through the front. His friends waited, called him, and eventually went home. Monday morning, he never showed up for his flight. Up to 50 officers searched at a time in those first days. Over the years, police have sifted through more than 5,000 tips. His phone was never used again. His bank account was never touched. His credit cards were never charged. Two years later, his father, still searching, was killed when a tree fell on him in his own yard. Then in 2026, a podcast got a tip naming a possible person of interest. When they brought the name to a Columbus detective, they learned police had already been given that same name by one of Brian's friends back in 2006. 20 years later, no body. No arrest. No answer. He walked into a bar full of people, in front of cameras, and vanished. How?
