GREAT BEND, Kan. (AP) — The first-degree murder trial of a central Kansas man has been delayed until the suspect undergoes a mental health evaluation.

No new date has been set for the trial of Jeffery Wade Chapman after a hearing Monday on the defense motion seeking the evaluation. Chapman’s attorney said in a court motion that Chapman was experiencing hallucinations while jailed in Barton County.

Chapman is charged with killing 25-year-old Damon Galyardt, whose body was discovered southwest of Great Bend in November 2011.

A new trial date will be set after Chapman undergoes the evaluation at Larned State Hospital’s forensic unit.
