Oklahoma’s labor commissioner was allegedly fatally stabbed by his son at an Oklahoma City restaurant on Sunday, Fox News reports.

Mark Costello, 59, was rushed to the hospital, where he was pronounced dead.

Authorities say Costello was meeting with his son, Christian Costello, 26, at a Braum’s ice cream and fast food restaurant on May Avenue, north of Hefner Road. Police say the stabbing took place inside the restaurant, after which Mark Costello stumbled outside to the parking lot to get help, where he was stabbed again.

Witnesses told police the two men got into a heated argument. They also reported seeing the suspect stab Mark Costello repeatedly from behind and then stab him again in the parking lot, according to KOCO-TV.

Mark Costello was found bleeding from stab wounds to the head and neck, according to The Oklahoman.

Cops said Christian Costello is in police custody on a first-degree murder complaint.

The Associated Press reported that Christian Costello previously disclosed that he had been confined for three months for treatment of mental illness and that he had been taking mood stabilizers.

He also has a criminal past: The Tulsa Word reports that he has been on probation since 2012 after pleading guilty to assault and battery, driving under the influence of a drug and failure to obey a traffic control device. Last year, the paper reported he was charged with outraging public decency, for which he’s due in court in October.

A successful businessman from Bartlesville, Mark Costello was elected labor commissioner in November 2010, taking 64 percent of the vote.

“Our hearts ache as an agency for this tragic event and our department grieves for his family during this very difficult time,” Labor Department Chief of Staff Jim Marshall said in a statement shared with Fox.

He is survived by his wife and their five children.
