OKLAHOMA CITY (AP) – Oklahoma City police investigators believe the deadly stabbing of a prominent politician by his son was a premeditated attack and that the suspect intentionally separated his father and mother before the assault took place.
Those details were disclosed in a police affidavit filed Wednesday as part of a request for a search warrant for a condominium where 26-year-old Christian Costello lived. Costello has been jailed on a preliminary charge of first-degree murder for the Sunday night stabbing death of his father, Oklahoma Labor Commissioner Mark Costello.
Inspector Cris Cunningham wrote in the affidavit that Christian Costello asked to speak to his father alone, “thus separating him from another family member who was present at the location.”
Cunningham wrote that no items were taken during Tuesday’s search of the condo.
