Stafford began his killing spree along with his wife, Verna, and brother, Harold, on June 22, 1978. His wife flagged down the Lorenz family on the side of Interstate 35 near Purcell, Oklahoma when Melvin Lorenz, 38, his wife, Linda, 31, and their son Richard, 12, were traveling to North Dakota for the funeral of Melvin Lorenz's mother. Stafford then robbed and murdered the entire family.
Six days after the Sirloin Stockade robbery, Harold Stafford died in a motorcycle accident in Tulsa, Oklahoma. Police traced a woman who went to see his body at a local funeral home to Chicago, Illinois, where they found and arrested Verna Stafford. They soon apprehended Roger Stafford as well.  He was tried and convicted of all nine murders, and sentenced to death. His wife Verna testified against him, and divorced him while he was on death row. (She was sentenced to two life terms for her part in the crimes.) He remarried while awaiting execution.
