A Nichols Hills doctor moved a step closer Friday to either a trial or a plea agreement in his murder case.
Stephen Paul Wolf on Friday morning waived his preliminary hearing, conceding prosecutors have enough evidence against him for a trial. His next court appearance is set for June 30.
Wolf, who has a history of mental illness, is not denying he stabbed his 9-year-old son. Before a hearing in December, he told reporters: "Yes, I'm sorry. Of course, I'm sorry.”
He and his attorney are expected to use an insanity defense and seek treatment at a state mental hospital. "I assume that's the direction they're going,” the prosecutor, Suzanne Lavenue, said.
Defense attorney Mack Martin declined comment.
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.
