Robert Comer died Tuesday with a steady gaze and a defiant smile on his face, the first person to be executed in Arizona since November 2000.
  He was strapped to a gurney and covered up to his neck with a sheet.
  There was no sight of the catheter into his groin that made the lethal injection possible, no sight of the executioners on the other side of a wall.
  But Comer was smiling; he had petitioned the federal courts to stop his appeals and hasten his own execution. He was in control of his destiny.
  Comer brought a picture of his daughter with him to the death chamber and used his last words to say, "Go, Raiders."
