OKLAHOMA CITY (AP) — A judge has entered a not guilty plea for the son of Oklahoma's labor commissioner on a first-degree murder charge in the stabbing death of his father.
Christian Costello appeared in a video arraignment before Oklahoma County Special Judge Russell Hall Wednesday in connection with the stabbing death of his father, Oklahoma Labor Commissioner Mark Costello.
The 26-year-old Costello said nothing as Hall entered the not guilty plea and appointed the Oklahoma County Public Defender's Office to represent him. Hall set a preliminary hearing for Sept. 24.
Authorities say Costello pulled out a knife while he and his 59-year-old father talked Aug. 23 at an Oklahoma City restaurant. Police say they interviewed at least 17 witnesses, all of whom say they saw Christian Costello stabbing his father with a knife.
