Stone County authorities have charged two people with tampering with evidence in the death of Galena man.

Fifty-eight-year-old Billy Mack Walker was found dead northeast of Greenfield in late November. Officials said he died from a gunshot wound and ruled his death was a homicide.

On Friday, Stone County prosecutors charged 57-year-old Sheila Renee Phillips and 54-year-old Gerald Keith Hoffman, both from Galena, with two counts each of tampering with physical evidence in a felony prosecution. Prosecutors have not filed murder charges.

The Missouri State Highway Patrol says Walker was killed in Stone County before his body was moved to a rural road in Dade County.
