The Nebraska State Patrol has identified human remains found in western Nebraska in June after a gunman told police negotiators he had killed a Colorado man. The patrol said Tuesday that the remains are those of 38-year-old Josh Bullock, who had been missing from Denver since early December. Andres Gonzalez told negotiators during a June 12 standoff that he killed Bullock, whose burned pickup was found by a rancher Dec. 14 near Chadron. Gonzalez wounded three officers and a pharmacist he had held as a hostage before dying in a shootout with police. Investigators believe Gonzalez killed Bullock around Dec. 1. Bullock's remains were found June 21 near Chadron. Gonzalez's former girlfriend, 20-year-old Rose Siefke, of Hemingford, has been charged as an accessory in Bullock's death.
