Nancy Guthrie's abductor disclosed three major clues that he committed an "unsophisticated" crime, involving his weapon, the gloves and his disguise, according to a crime expert. "You have what appeared to be a semi-automatic gun and a revolver case, and then it appeared to be dangling where no shooter would really carry the gun, right in front of your private parts," Troy Hillman, a retired cold case homicide sergeant with Phoenix Police Department, exclusively told Us Weekly about the perpetrator's weapon seen on the 84-year-old's Nest camera from the morning of her February 1 disappearance.
