OKLAHOMA CITY (AP) – Oklahoma Labor Commissioner Mark Costello died Sunday after he was stabbed multiple times at an Oklahoma City restaurant and his son was arrested on a first-degree murder complaint, police said.

Officers were called to a Braum’s ice cream and fast-food restaurant on the city’s northwest side after a stabbing was reported, Oklahoma City Police Department Capt. Paco Balderrama said. Police said the altercation started inside the building and spilled into the parking lot, where bystanders helped subdue the attacker until officers arrived.

Costello was stabbed multiple times in the head and neck area, Balderrama said. He was taken to a hospital, where he died.

State Medical Examiner’s Office spokeswoman Amy Elliott said an autopsy would be performed.

Balderrama said Costello’s 26-year-old son, Christian Costello, was arrested on a first-degree murder complaint and was in police custody late Sunday night. Balderrama said he did not know whether the younger Costello had an attorney who could comment on the allegations.
