A preliminary hearing has been set for June 4 for the Nichols Hills doctor charged with murder in the death of his 9-year-old son. Stephen Paul Wolf, 51, was arrested Nov. 16 after a police officer found him straddling his stabbed son, Tommy, in the kitchen of their home, according to a police affidavit. He repeatedly told the police officer, "He’s got the devil in him and you know it,” according to the affidavit. His wife, Mary Wolf, suffered cuts to her hands and face when she intervened. The doctor is charged with first-degree murder in his son’s death and assault and battery with a deadly weapon in his wife’s injuries. At a preliminary hearing, a judge hears testimony and reviews exhibits to decide if the evidence is sufficient for a criminal trial. The doctor also is facing a civil suit filed by his wife in the attack.
