The Holly Bobo case

Bobo was 20 when she disappeared. Her brother told police that he saw a man dressed in camouflage leading her away into the woods. Investigators and volunteers scoured the woods and fields of the town of about 2,400 for clues, but her remains were not immediately found.

Gwyn has said the Bobo investigation has been the most expensive and exhaustive in TBI history, and it's not over yet.

Since Bobo disappeared, the small town of Parsons and surrounding areas in West Tennessee tried to support the family, putting up pink ribbons on lampposts, mailboxes and storefronts. Bobo was wearing a pink shirt and carrying a pink purse before she disappeared.
