Appalachian Unsolved

Wealthy Knoxvillian Rose Busch was home alone icing a cake when a killer knocked on her back door.

Fifty years later, the murderer remains free.

Bizarre clues left in the neighborhood included a gun silencer and a policeman’s uniform.

Why the case likely never will be solved.

At first, it appeared real estate entrepreneur Shannon Hercutt died after her Cadillac plunged in August 2009 over a Sevier County, Tennessee cliff.

Several days later, police realized she’d actually been killed and the crash made to look like an accident.

Hercutt’s sister accused their father of hiring someone to kill Shannon. Authorities, however, don’t think that’s true.

Thousands of dollars in reward money remains available for the tip that breaks the case. The killer, however, still walks free.

Popular radio host Gus Gossert once had thousands of music fans who listened to his broadcasts of the golden oldies.

Then a gunman shot him to death off a remote road in West Knox County.

Was it drugs? Money? Revenge over a woman?

More than 40 years later it’s still an unsolved killing.

Widow Frances Worthington, 77, lived a quiet life in her South Knoxville home. Then a killer busted in on New Year’s Eve 1995.

What that person did was horrendous – wrecking her home, bludgeoning her, sprinkling coins and mini chocolates around her body, violating her with a wine bottle.

How her family responded was remarkable. They forgive whoever committed this still-unsolved murder.

Bradford Bishop aspired to be a U.S. ambassador. Tormented by doubt, depression and money troubles, investigators believe he ended up killing his own family in a murder mystery that wound up in the Great Smoky Mountains National Park.
