In the fall of 1973 the community of Ardmore, Oklahoma, was shaken when 47-year-old high school teacher and coach J.C. Dunn was found fatally shot in the neck with a shotgun in his home. Dunn had gone to the high school on the morning of October 24 and left after first period, saying he wasn’t feeling well; his wife Betty discovered his body later that day in the bathroom.

Authorities quickly treated the death as a homicide rather than a suicide. Investigators reported several inconsistencies: the shotgun at the scene had been wiped clean of fingerprints except for Dunn’s, no spent shells were found in the bathroom, and Dunn’s wallet and money clip were empty. The district attorney described the killing as an execution-type slaying staged to look like suicide. Police questioned a 68-year-old rancher who had spent nights at the Dunn home and whose shredded checks to Dunn were recovered, but that man was cleared after passing a polygraph. More than a dozen people have been interviewed over the years, yet the case remains unsolved.

Does anyone in the Ardmore area from that era have recollections or information that could help finally close this case?
