Six Graves at Cripple Creek - S3.E19

Emmett Ryker learns that a man named McMasters, who had killed his good friends, a rancher and his daughter, two years before, was one of six men supposedly killed by Indians. Believing the man still alive, and seeking revenge, he accompanies a young woman, Lucille Carver (Sheilah Wells), whose father was also reported as among those killed, to the massacre site at Cripple Creek. The trail eventually leads him to Deadwood where he suspects a man who has made a gold strike, and may be Lucille's father, is McMasters.
