PRESCOTT, Ariz. (AP) — Arizona jurors have convicted an Oregon man of second-degree murder and other charges stemming from the disappearance of a mining claim partner whose body was found buried in the desert a decade later. A Yavapai County Superior Court jury in Prescott on Thursday convicted 59-year-old Anthony James Richards of Terrbonne, of second-degree murder in the killing of Larry Powers. The County Attorney’s Office said Richards also was convicted of trafficking in stolen property, theft of a credit card, forgery, and 19 counts of taking the identity of another. Richards faces at least 16 years in prison when he is sentenced May 16.
