The Tennessee minister found beaten and burned to death on his mountain retirement land had been trying to help the stranger charged with killing him, investigators said Wednesday.
Investigators believe Rev. William B. Petty Jr., 56, was driving through Chattanooga, Tenn., on Saturday when he saw Nathan Hass hitchhiking and offered him a ride.
At some point, Hass clubbed the minister with a piece of wood, then set his body on fire on Petty's property near the North Carolina border and fled in the cleric's car, investigators said Wednesday.
Hass, 30, and his wife, Denise, 29, were arrested Wednesday at a Missouri campground near St. Louis. Hass was charged with felony murder and car theft. His wife was charged with accessory to arson.
Investigators said Hass picked up his wife after the killing and the two fled westward. Petty's car was found burned Monday near Andrews, N.C., where the Hasses lived.
Petty, who lived in Ooltewah, was a lawyer in Chattanooga for 30 years, then left his practice to become a United Methodist minister. He led five small congregations in southeastern Tennessee.
