Jesse Durham has filed notice that he will use a mental health defense in his murder case.
Durham, 22, is accused of killing his great-grandmother, Elizabeth Arinsmier, with a hammer. He has pleaded not guilty to murder, which carries a sentence of as much as life in prison.
Earlier this month, Durham's attorney, C.B. Bates of the Department of Public Advocacy in Columbia, announced that the case is prepared for trial.
