OKLAHOMA CITY - People across Oklahoma are pouring out their support for the family of Oklahoma Labor Commissioner Mark Costello.
The 59-year-old was stabbed to death Sunday night after meeting with his son at a Braum’s store near May and Hefner.
Christian Costello was arrested after witnesses took him down following the attack, holding him until police arrived.
Oklahoma City Police said Monday their investigation continues, interviewing more than a dozen people at the scene.
They’re also looking into whether surveillance video captured the crime.
Investigators say the father and son had agreed to meet at the restaurant when, for some reason, things got out of hand.
Mark Costello was stabbed multiple times.
Monday, Gov. Mary Fallin offered her condolences to Costello’s family as leaders from across our state are speaking out.
An old campaign sign for Mark Costello was surrounded by flowers Monday outside GOP headquarters.
“I was shocked and greatly saddened to hear of Labor Commissioner Mark Costello’s tragic death last night." Fallin said. "My prayers and deepest sympathies go out to his family, friends and staff. Oklahoma has lost a dedicated public servant and a good man.”
“I for one and my family have been very, very proud to know Mark Costello and it was just a shock to hear the news,” Insurance Commissioner John Doak said.
Doak met Costello in 2010 when they were both running for state offices.
“He was a statesman, he treated people with respect, even if they didn’t hold the same values or political position,” Doak said.
Costello was elected to labor commissioner in 2010.
Pam Pollard, President of the Oklahoma Federation of Republican Women, met him on the campaign trail.
She said he was energetic and ready to serve.
“Knowing the family, knowing Mark, knowing the good he wanted to do for Oklahoma, Mark wasn't a politician, even though he was elected to office," Pollard said. "Mark was a genuine man who was looking for the betterment of all Oklahomans."
Costello was born in Bartlesville.
He's survived by his wife Cathy and five children.
His friends say he hoped to run for higher office.
Commissioner Doak says Costello will be remembered for his values.
“I hope that folks, when they look at politicians, they look at the life of mark Costello, and they see it’s something that can be admirable, is a worthwhile investment to give back to the state of Oklahoma,” Doak said.
It'll be up to Fallin to appoint a new labor commissioner, and that person will finish Costello's term through 2019.
The funeral will be held this weekend.
The rosary will be Friday evening at 6:30 p.m. at St. Monica Catholic Church, 2001 N. Western Ave, Edmond.
The funeral mass will be held at 10 a.m. Saturday also at St. Monica Catholic Church.
