In 1989, the dead bodies of Joan Rogers and her two teenage daughters were found floating in Tampa Bay. The water washed away any evidence, but police hoped a handwritten note found in the victims' car would lead to the killer, so they posted huge copies of the note on five highway billboards. By doing this, they received a call from a woman, for whom Oba Chandler had done work, and they positively identified his handwriting, as well as a palm print left on the note.
