CAN YOU HELP?
Oklahoma Cold Cases is focusing on the murder of Mary Harrison throughout the day on Facebook today.
The County Sheriff's Office , OSBI and other organizations will also be posting information about Mary.

If you have information or may have heard something, please contact Lt. Mike Shults at the Kingfisher County Sheriff’s office at 405-375-4242.

Today is a special day dedicated to our 2025–26 Case of the Year: the unsolved murder of Mary Harrison. On a cold, windy Saturday in January 1977, 63-year-old Mary Harrison was heartlessly attacked in her own home on her farm outside Kingfisher, Oklahoma. She was stabbed over 40 times and nearly decapitated in a frenzied assault.

Almost fifty years later, the same questions remain. Mary’s family, friends, and community still don't know who killed her or why. Countless hours of investigation by law enforcement have yet to provide answers.

We are asking you, our friends and followers, to please help by sharing our posts. Every share could bring Mary's family one step closer to the answers they deserve.
On behalf of the Harrison family and Oklahoma Cold Cases, thank you for helping us keep Mary’s story alive. 🙏

In 1977, Mary Harrison was 63 years old. After a 20-year career with the .S. Department of Agriculture, she was ready to enjoy a well-earned retirement on her farm outside Kingfisher, Oklahoma. Mary delighted in her two grandchildren, and with more free time on her hands, she looked forward to spoiling them and enjoying the next chapter of life.

Sadly, that simple dream was stolen on January 8, 1977, when someone brutally stabbed Mary to death. Her murder remains unsolved, leaving her family without justice and still searching for answers.
