Roy Hill, a 79-year-old World War I veteran, was found dead in his Tulsa home at 2611 E. 29th Street North on the afternoon of November 6, 1971. Neighbors who had not seen him for a couple of days looked into his residence and discovered him sitting unresponsive in a chair; police later determined he had suffered a fatal stab wound to the neck.

The last known sighting was on November 4, when his sister visited him around 5 p.m. Hill was born in Arkansas on February 25, 1892, enlisted January 15, 1919, served in the First World War, worked in the railroad industry, and had been married around 1920 to a woman named Gertrude; the couple had no children. The homicide remains unsolved and no suspects or arrests have been publicly identified.

Did anyone in the Tulsa area remember seeing Roy or his home around November 4–6, 1971?
