One of the most debated questions in the disappearance of Brian Shaffer is whether he intentionally vanished. Investigators examined that possibility early in the case, but Brian left behind a life that appeared full of future plans, including medical school and an upcoming vacation with his girlfriend. Nearly twenty years later, there is still no confirmed evidence that he chose to disappear.

In this episode of Unsolved and Missing, we examine the voluntary disappearance theory, why it continues to circulate online, and what the known evidence actually suggests.
