Authorities say that Oklahoma Labor Commissioner Mark Costello died Sunday night after being stabbed numerous times, and his son had been arrested on a first-degree murder complaint.

Balderrama said that Costello's 26-year-old son, Christian Costello, has been arrested on a first-degree murder complaint. Mark Costello was married with five children, and the founder of a telephone software company. The Republican was first elected to labor commissioner in 2010, and easily won reelection in 2014. In a statement, Labor Department Chief of Staff Jim Marshall said "our hearts ache as an agency for this tragic event and our department grieves for his family during this very difficult time."
