So why did 24-year-old Jennifer Kesse (pictured below) vanish into thin air? On the morning of Tuesday, January 24, 2006, Jennifer Kesse failed to show up for work. A project manager for Central Florida Investments, the Orlando, Florida resident was known for her reliability. If she was running late, she always called. She was constantly in touch with her family and friends, but on that winter morning eight years ago, nobody heard from Jenn. And that meant something was drastically wrong.

The story of Jennifer’s disappearance is filled with bizarre clues, a long list of possible suspects and a mysterious figure caught on videotape. Greta Van Susteren has known the Kesse family since 2006 when she met them in Orlando just days after Jennifer first went missing. 

She’s chronicled all the twist and turns over the years in a case that she says “haunts me to this day.” Her heartbroken father, Drew Kesse, told Greta that “we no longer care why, who, when and where. We don’t care. We simply want Jennifer back.”

Fox News recently sat down with the Kesse family, Jen’s boyfriend, her best friend, a co-worker, and an Orlando police detective. All are completely baffled to this day by her disappearance. One reporter who covered the story told Fox News that “this was the first case I lost sleep over.” 

In a must-see special, Greta goes deep inside a chilling mystery that has yet to be solved. Check out a sneak peek clip above, and tune in Friday at 7p ET and Saturday at 9p ET to “Greta Investigates: The Mysterious Disappearance of Jennifer Kesse.”
