Treva K. Cannon

Tuesday, August 23, 1983
Treva K. Cannon, 327 11th NW, Ardmore, was found dead in her white frame house. An investigation determined she had been struck with a blunt object, killing her. Carter County District Attorney Ron Worthen, and Oklahoma State Bureau of Investigation (OSBI) agent and Ardmore police were at the scene late Tuesday morning waiting for an OSBI lab team from Oklahoma City. “We don’t really have a lot right now. We haven’t touched anything waiting on the lab team,” Worthen said late this morning at the scene.

Shirley Stinson, a neighbor, said she heard a “banging noise” around 1 a.m. and got out of bed to check. “My son had just gotten home from work and was writing a letter to his girlfriend. So I didn’t think much about it,” the neighbor said.

Brenda Sparlin, a neighbor, said, “She usually leaves for work at 7:30 a.m. but her car was still there….. I tried to call twice before I went over there.” “I knocked and she didn’t answer. The front door was open and when I walked to the back and the back door was open. I saw her in the front bedroom.”

Ms. Cannon was a social worker for the Department of Human Services at the Pauls Valley State School. She formerly taught at Springer junior and senior high schools, and Ardmore Junior High School. Mrs. Cannon received a bachelor’s degree in business administration from Texas Tech University and a master’s in education from East Texas State Teacher’s College.
