ATLANTA (AP) — Authorities are offering a $10,000 reward as they continue to search for the person who shot actor Thomas Jefferson Byrd in Atlanta.

The reward was announced Tuesday. Police have not identified a suspect in the 70-year-old actor’s shooting death or said why it may have happened.

Byrd was found shot near his home and died before he could be taken to a hospital. Robert Calloway told WSB-TV he found Byrd in a yard and ran to a fire station for help. Calloway didn’t know Byrd.
