It's as if Gayle Fleming vanished into thin air. The 63-year-old woman was last seen by distraught her family at their Clemmons, North Carolina home on April 17.

A few days later her 2002 Lexus was found in a lot at nearby Tanglewood Park. The car doors were locked, her keys gone and the driver's seat was in a position consistent with someone of her size.

The Forsyth County Sheriff's Office and the community have organized numerous searches, looking for any clue Gayle had been in the park.

Bloodhounds were given a pillowcase of hers to try to track her scent, and a North Carolina state highway patrol helicopter was brought in to search the park from the sky.

The results of all these efforts are bewildering: Absolutely nothing has turned up.

Sheriff's investigators are following up on multiple leads.
