It’s the kind of detail that lingers: a meeting, just after midnight… that no one can explain. In May 1997, 20-year-old Keith Mann was building a future—new apartment, new job, new fiancée. But sometime after being dropped off at home late that night, Keith stepped back out into the dark to meet someone. By morning, he was gone. The only thing left behind was a borrowed car from the dealership he’d been working at. Found abandoned in a church parking lot right next to his parent’s home.
