OKLAHOMA CITY (AP) -- A man accused in the stabbing death of his father, Oklahoma's labor commissioner, is set to appear in court.
Oklahoma County Special Judge Lisa Hammond is scheduled to convene the hearing Thursday for 26-year-old Christian Costello, who is charged with first-degree murder in the killing of 59-year-old Mark Costello.
Prosecutors say Christian Costello attacked his father with a knife and repeatedly stabbed him on Aug. 23 at a northwest Oklahoma City restaurant. A judge has entered a not guilty plea on Christian Costello's behalf.
