A Kentucky sheriff offering his own reward money in hopes of solving three murder cases is being asked to turn over his information in one of the slayings. Commonwealth's Attorney G.L. Ovey has filed a motion asking Trigg County Sheriff Ray Burnam to appear in court Wednesday with his file on the Chantell Humphries murder case. Humphries' body was found on a Trigg County cattle farm a decade ago. A trial earlier this year ended in a mistrial.
