Police say Ben Fawley, a 38-year-old amateur photographer, was one of the last people to see Behl the night she vanished.
It's believed she left her dorm room with her a cell phone, some cash, identification and car keys, reports Rene Syler.
Twelve days later, police found her car a mile-and-a-half from campus.
At the time, Chief Rodney Monroe called it "a very big piece in the puzzle, and hopefully, once we have an opportunity to search the vehicle further, it can give us more information."
Behl's acquaintance with Fawley could be another piece of that puzzle, Syler says.
They met through his former roommate, who says Fawley took pictures of Behl and posted them on his Web site.
Behl's friend, Mike Cino, says, "They'd been talking for a while online … and it's possible she considered him a confidante of sorts."
Cino says Fawley was drawn to younger friends.
