Bismarck man arrested in Moorhead pleads not guilty in mother's killing
Dean Grenstiner, 47, of Bismarck, is charged with murder and felony theft in connection with the death of his mother, Ann Grenstiner, whose bloodied body was found in the bedroom of her Bismarck home on March 27. Autopsy reports said Ann Grenstiner, 83, had been bludgeoned about the head.
Grenstiner entered his plea during a brief arraignment in South Central District Court in Bismarck. The hearing had been delayed while he underwent an independent psychiatric evaluation.
Grenstiner's attorney, William Mackenzie, had hinted his client would claim he was not responsible for the crime because of mental illness. However, Grenstiner's plea did not make any reference to his mental state at the time of his mother's death.
Mackenzie did not respond to a request for comment afterward.
Grenstiner is being held without bail in the Burleigh County jail. Authorities say he had been living with his mother for more than a month before she was killed, and a friend of his also lived at the home briefly.
After Ann Grenstiner's body was discovered, police found her son in Moorhead and her car in the parking lot of a bar in Fargo. Ann Grenstiner's neighbors said she had not allowed anyone else to drive her car, a new 2012 silver Honda CR-V.
Grenstiner is due back in court Aug. 27.
