Agents Investigate Kiowa County Murder/Mangum Suicide

The Kiowa County Sheriff's Office requested OSBI assistance on a woman found dead on her property along the Red River in rural Kiowa County about 6 p.m. Tuesday. Lorhetta Sue Ketchersid, 55, did not show up for work or contact anyone. Worried friends and family began searching for her. Ketchersid's pastor searched her property and found her body. Overnight, OSBI developed information leading to a person of interest -- Joseph Dhayer (d.o.b. 7-31-66) of Mangum. Around noon today (3/30) OHP Troopers pulled over Dhayer on a traffic stop near the intersection of Taft and Byers Streets in Mangum. Dhayer immediately shot himself in the dead. OSBI Agents continue to investigate the murder of Ketchersid.
