Christian Costello ordered to stay in psychiatric hospital after killing father

OKLAHOMA CITY (AP) – An Oklahoma man who killed his politician father has been ordered to remain in a state psychiatric hospital.

The Oklahoman reports that Oklahoma County District Judge Ray Elliott ruled Thursday for 29-year-old Christian Costello to stay in the Vinita mental hospital. The ruling comes after a psychiatrist and psychologist both determined last month Costello requires ongoing inpatient treatment and remains dangerous to the public.

Costello in August 2015 fatally stabbed 59-year-old Mark Costello, his father and the state’s labor commissioner. Christian Costello was found not guilty by reason of insanity in April after telling the judge that killing his father was “destiny.”

Doctors say Costello has a history of mental illness and manic episodes. He has been diagnosed with schizoaffective disorder.

Defense attorneys agree Costello should stay hospitalized.
