For nearly two decades, local and federal authorities have followed dozens of leads on the hunt for Kemberly Ramer, yet her disappearance remains a complete mystery, with not a trace of her to be found. She was last seen leaving her boyfriend's house around 10pm on Aug. 15, 1997, a happy 17-year-old who'd just taken her senior portraits the day before, but by the next morning all that remained of her was evidence that she'd likely spent the night in her own bed at her father's home in Opp, Ala.—her rumpled sheets, car, clothes, and contact lenses, reports NBC News. And that's it. Investigators have looked everywhere: in a well, a sinkhole, a baptism hole, and beyond, but the trail is clean and it is cold.
Because there was reason to believe Kemberly may have crossed state lines (Opp is close to the Florida border), the FBI was and continues to be involved in the case. Just last year a lead that came from a source close to persons of interest led to a full day of digging, but once again not a shred of evidence was found, reported the Andalusia Star News in March. "She was a great daughter," her mother, Sue Infinger, tells NBC. "She was just so happy." If she's alive, Kemberly is 36. Her father died several yeas ago, and her mother is now 63. "I don't know why anyone would want to hurt her," she says. But "I believe it was someone she knew." (See how a Reddit user helped solve this 20-year-old mystery.)
