FLAGSTAFF, Ariz. AP – An Arizona man being held on a murder charge made surprise confessions in two other killings, and told authorities he would have continued on a vigilante-style killing spree if he hadn’t been caught, authorities said Wednesday.

William Inmon of the rural eastern Arizona town of Springerville is among four people charged in the death of 16-year-old Ricky Flores from nearby St. Johns. Flores’ body was found burned and buried in a shallow grave two weeks after his mother reported him missing on Aug. 14.
