NICHOLS HILLS - The doctor accused of fatally stabbing his son Monday repeatedly said his son had "the devil in him," police reported today in a court arrest affidavit.

Stephen P. Wolf, 51, tried to stab his son again even after a police officer broke up the assault in the kitchen of the home at 1715 Elmhurst Ave., according to the arrest affidavit.

Wolf is in the Oklahoma County jail. His son, Tommy, was 9.

The doctor has a history of mental issues that included hospital stays for depression. He saw a psychotherapist in the 1980s while in medical school and was under the care of a psychiatrist in 1996, his medical records show.
