OKLAHOMA CITY (AP) – Oklahoma’s labor commissioner died after he was stabbed multiple times at an Oklahoma City restaurant, and his adult son was arrested on a first-degree murder complaint in the slaying, police said.

Officers were called around 6:30 p.m. Sunday 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 found Labor Commissioner Mark Costello stabbed multiple times in the head and neck, Balderrama said. Costello, 59, was taken to a hospital, where he died.

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

Police said an altercation started inside the building and spilled into the parking lot, where bystanders helped subdue the attacker until officers arrived.

Costello’s 26-year-old son, Christian Costello, was taken into custody in the parking lot and arrested on a first-degree murder complaint, Balderrama said. He remained in police custody late Sunday night.
