Maryville, TN (WOKI) Maryville Police solve a decades-old cold case making an arrest.

The case centers on the 39-year-old cold case murder of Billy Wayne Hearon. Police have charged 62-year-old Roger Oody in his murder.

Hearon was found dead in his home in Shady Acres Trailer Park, MPD said, adding that he had died from several stab wounds and trauma to the head.

Oody was convicted previously of killing Roy Stevens in the 1980s in Monroe County. He is currently serving a life sentence for that conviction.

Oody was a person of interest during the initial investigation into Hearon’s murder, and new evidence and technology helped investigators charge him.

He will make his initial appearance in court on Friday.
