Christian Costello to be arraigned

OKLAHOMA CITY (AP) – The son of Oklahoma’s labor commissioner is scheduled to be arraigned on a first-degree murder charge in the stabbing death of his father.

Christian Costello is scheduled to appear before Oklahoma County Special Judge Russell Hall Wednesday in connection with the stabbing death of his father, Oklahoma Labor Commissioner Mark Costello.

Authorities say the 26-year-old Christian Costello pulled out a knife while he and his 59-year-old father talked Aug. 23 at a fast-food restaurant in Oklahoma City. Police say they interviewed at least 17 witnesses, all of whom say they saw Christian Costello stabbing his father with a small knife.

The Office of the State Medical Examiner has ruled that Mark Costello died from stab wounds to the neck and classified his death as a homicide.
