OKLAHOMA CITY – A man accused of killing the Oklahoma Labor Commissioner was found mentally competent to stand trial for first-degree murder.

Christian Costello is accused of stabbing his father Mark to death in a Braum’s parking lot in August 2015.

Costello’s family says he suffers from a mental illness and court records show Costello previously spent 90 days in a mental health facility and took mood stabilizers.

In May, Costello went before Judge Ray Elliott for a pre-trial hearing.

During the hearing, Costello told the court that he “wanted to plead guilty and go to Minnesota to meet with a pediatrician that once helped him,” according to Ravitz.

After listening to the plea, Elliott ordered the Oklahoma State Department of Mental Health to examine Costello to see if he was competent enough to enter a guilty plea.

In August 2016, the judge was scheduled to decide whether Costello was mentally competent to plead guilty.

In a report filed by the Oklahoma Department of Mental Health, a psychiatrist wrote that Costello has a severe mental disease, Schizoaffective disorder.

The psychiatrist who examined Costello said the defendant suffers from paranoid delusions and is mentally incompetent to stand trial for first-degree murder.

The report states that while Costello understands the charges filed against him, he is not able to consult with his attorney and rationally assist in the preparation of his defense.

During the hearing, Costello delivered a rambling minute-long diatribe.

He admitted to killing his father, saying he was a “hit man” and the killing was part of a “military operation.”

Costello also stated he does not apologize for killing his father.

He said his father would have killed him.

Costello then went on to say that he was a slave and that he sold his soul to Hillary Clinton.

After reviewing the report, the prosecution asked that they get their own evaluation.

The judge approved the request and scheduled another hearing.

Today, the judge found Costello mentally competent to stand trial.

His trial date is scheduled for April 3, 2017.
