Twisted Tale

It remains the most complicated bank robbery investigation in the FBI’s history.

CNN's Drew Griffin digs deep into what happened when a 46-year old pizza delivery man walked into an Erie, Pennsylvania bank wearing a bomb attached to his neck and demanded $250,000 in cash.

Brian Wells ultimately was killed when that bomb went off. But it wasn’t until seven years later that the government finally declared it had solved the case and that Brian Wells was in fact complicit.

His family bitterly disputes that and we track down a man the FBI admits took part in the robbery but was never prosecuted.

Three riveting stories. One hour not to miss.
