Jury hears expert’s analysis of Duncan
INDIO - Joseph Duncan, charged with the 1997 murder of a Beaumont, Calif., boy, is too delusional and psychotic to make his own decisions and understand his death penalty trial, a court-appointed defense attorney said Monday.
Prosecutors, however, argued that Duncan knew exactly what he was doing when he killed Anthony Martinez, 10.
The attorneys made their statements at the start of a trial in Indio to determine whether Duncan is competent to face murder charges in Anthony’s death.
Duncan was extradited from Idaho, where he had pleaded guilty to murdering a woman, her boyfriend and 13-year-old son. He also kidnapped and molested the family’s 9-year-old boy and 8-year-old sister. Duncan killed the boy and hid with the girl in the mountains for two months before he was arrested.
