Using DNA technology to link Griffin to a bloody dollar bill and hairs found at the murder scene, the state proved that Griffin bound, bludgeoned, robbed and murdered the 22-year-old clerk at a convenience store near Brigham City on May 26, 1984. The jury deliberated a total of 12 hours Thursday evening and Friday morning before returning the verdict in the Logan 1st District Court shortly after noon today. When polled by Brigham City-based 1st District Judge Ben Hadfield, each of the 12 jurors said Griffin was "guilty" of aggravated murder, robbery, kidnapping, plus aggravated robbery and aggravated kidnapping. Griffin's mother, Arlene Pyle, and other family members wept openly as he was removed from the courtroom to change from his business suit into an orange prison jumpsuit and shackles. The penalty phase begins at 9 a.m. Tuesday in the Logan 1st District Court.
