Tioga County in upstate New York is the kind of place where people go to escape the problems of the big cities. So when 35-year-old Michele Harris disappeared, it mystified State Police Captain Mark Lester. "A murder in Tioga County, it's a pretty rare occurrence… For an actual person to go missing and not be able to find 'em is extremely rare," he said. "And normally, you would expect at some point along this way we're gonna find her … And we still haven't been able to find her remains." In the early morning hours of Sept. 12, 2001, Michele's van was found at the end of her driveway. "There was a gut feeling I think right from the get-go that something was wrong," Lester told "48 Hours Mystery" correspondent Erin Moriarty.
