AI Summary

5 min read

On the night of May 10, 1997, 20-year-old Gregory "Keith" Mann Jr. told his coworkers he had a secret meeting at 12:15 a.m. He smiled and shrugged when they pressed for details. He was never seen again. The next day was Mother's Day, and his fiancée Carrie was supposed to move into their new apartment. Instead, she found his bed unslept in and his work clothes on the floor. Keith had a good job selling cars at Ron Roberts Ford, a new apartment, and a fiancée about to move in. He had two commission checks waiting for him on Monday and money in his bank account that was never touched. He did not run away. Someone else was driving the car he borrowed from the dealership the night he disappeared—the seat was pushed back for a taller person. And that car was found abandoned in a church parking lot across from his parents' house, trunk popped open, with a cassette tape partially ejected. This is the story of a disappearance that has left almost no trace.

Show Notes

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. Decades later, that midnight meeting is still a mystery. No one has ever come forward. If you remember Keith or anything about his life in Wichita Falls in 1997, his family is still searching for answers.
