When Schober got out of his pickup truck, he saw two men on the pavement, both shot. One was Ed Andersson, an injured Arizona state trooper. The second was a man authorities said had been beating the trooper after shooting him twice. The man who flagged Schober down had fatally wounded that attacker minutes before Schober stopped to see what was going on. A woman was on the ground, too, having been ejected from a car that had crashed off the side of the highway.
