Police in Harrisburg, Pennsylvania, had no idea that throughout the late 80s and early 90s, they had a serial killer on their hands, and not just any serial killer, but one who would become one of the most prolific in the state.

MISSING: Christopher “Cole” Thomas
On Black Friday 2016, 22-year-old Christopher “Cole” Thomas was driving through rural North Carolina with two coworkers. Hours later, the coworkers approached police and said Cole had suddenly panicked, pulled over, and ran into the dark, never to be seen again.
MISSING: Gregory ‘Keith’ Mann Jr.
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. You can share information or memories through the Missing Mann Project website or connect with them on the Missing Mann Project Facebook page, where they continue to keep Keith’s story alive – and hope that one day, the person he went to meet will finally be known.
MISSING: Melissa Casias
In June 2025, Melissa Casias dropped her husband off at work in Los Alamos, New Mexico… then did something nobody expected. She turned around and drove home. By that afternoon, she had vanished, leaving behind her wallet, her keys, both of her personal phones wiped to factory settings, and a family already splitting in two over what to believe. Her husband, Mark, insists she walked away on her own. Her parents and siblings are certain something far worse happened to her. Surveillance video proves she was alive walking along Highway 518 that day. But where she went next – and why – is a question that only deepens the further you pull at it.
