BISMARCK, N.D. (AP) - A man who's accused of killing his mother and stealing her car says he's not guilty of the crimes.
Dean Grenstiner made his pleas Monday during a brief appearance in state district court in Bismarck.
Grenstiner's arraignment was delayed last month so that he could undergo an independent psychiatric examination. However, his plea Monday didn't make any reference to his mental health.
Grenstiner is being held without bail at the Burleigh County Jail on charges that he beat his mother to death in her home last March. Authorities say Grenstiner was living with his mother, Ann Grenstiner, for several weeks before she was killed.
Grenstiner was also charged with stealing his mother's car. He was arrested in Moorhead, Minn., the day after his mother's body was discovered.
