Oklahoma City police said Christian had an argument earlier in the day with his father, State Labor Commissioner Mark Costello. The two agreed to meet at the restaurant to work things out.

Witnesses told investigators that Mark Costello was stabbed inside the restaurant, and as he tried to leave, witnesses said Christian followed his father to the parking lot and stabbed his father in the back of the head with a steak knife.

According to police, Costello was stabbed at least four times. 

According to witness Patrick Spencer, someone in the parking lot used their SUV to hit Christian to stop the attack.

"It knocked him to the ground and several people who were here were able to get the knife away from the suspect and knocked him to the ground, and they tied him up with belts and they were able to keep him under wraps until police got here," Spencer said.

Costello was transported to OU Medical Center but was pronounced dead. According to his bio on the state's website he has been married to his wife Cathy for 33 years and has five children.

His oldest son Christian is now in police custody.
