It's been called one of the most atrocious unsolved murders ever in Jackson County.
Sixteen-years-ago, the bodies of 25-year-old Teresa Hall and her five-year-old daughter, Tiffany, were found inside their Cypress Community home.
Each had been bludgeoned to death with what is believed a hammer, but the weapon has never been found.
The mother and daughter were last seen alive on December 9th, 1991 at the Marianna Christmas Parade.
Over the years, several persons of interest have been questioned about the double-homicide, but an arrest has never been made.
Authorities continue to track down leads.
Anyone with information should call Jackson County Crime Stoppers at 850-526-5000.
