HAILEY, Idaho (AP) — The trial of a man facing a first-degree murder charge has been vacated after a psychologist determined he's mentally incapable of assisting with his own defense.

The Idaho Mountain Express reports that a 5th District Court judge on Tuesday ordered 38-year-old Harley Park placed into Idaho Department of Health and Welfare custody for 90 days for re-evaluation.

Police say that Park in 2003 killed 61-year-old Lynn Stevenson at a nine-hole golf course Stevenson owned near Soldier Mountain north of Fairfield.

Park was determined to be "dangerously mentally ill" in 2006 and deemed unfit for trial. He spent 12 years in a psychiatric hospital until April 2015 when doctors with Health and Welfare found he was fit to stand trial.
