Christian Costello was charged with first-degree murder on Monday – a week after he allegedly stabbed his politician father, Mark Costello, to death.
Christian, 26, reportedly met his father, the Oklahoma labor commissioner, at a Braum’s ice cream and fast food restaurant on Aug. 23. According to police, the stabbing occurred inside but the attack continued after Mark, 59, made his way outside for help, according to the Associated Press.
Witnesses told authorities that the father and son got into a heated argument before the stabbing. KOCO reports that a witness hit Christian Costello with his SUV to stop the attack and other witnesses held him until police arrived. The labor commissioner suffered multiple stab wounds to the head and neck.
Prior to the fatal incident, Christian had been admitted to a mental health facility for three months.
Christian has one pending misdemeanor charge of “outraging public decency” against him, from an unrelated incident in which he was allegedly found outside of an elementary school with his pants pulled down.
He is being held without bond in the Oklahoma County Jail, ABC 8 reports.
