Gun Street (1961)

In this movie filmed and released in 1961 (and not a 1962 production), an escaped convict returns to town and begins a reign of terror. Marked for death are Dr. Dean Knudtson, his wife Janice, formerly married to the killer, and Jeff Baxley, on whose testimony the man was originally sent to prison. Sheriff Charles Morton and deputy Sam Freed head a posse tracking down the killer in the desert. The man is found dead of the wounds inflicted by a prison guard trying to prevent his escape. The sheriff resigns his job and heads west with Joan.
