Book excerpt: "On December 6, 1991, the naked, bound-and-gagged bodies of ... four girls--each one shot in the head--were found in an I Can't Believe It's Yogurt! shop in Austin, Texas. Grief, shock, and horror spread out from their families and friends to overtake the city itself. Though all branches of law enforcement were brought to bear, the investigation was often misdirected and after eight years only two men (then teenagers) were tried; moreover, their subsequent convictions were eventually overturned, and Austin PD detectives are still working on what is now a very cold case"--]cProvided by publisher.
