there is still debate and some doubt. this time you can be the judge and the jury. we'll lay out the evidence on both sides, and you'll hear from wayne williams at length. then we'll invite you to reach your own verdict, guilty, innocent, or a third choice, not proven. the first clue was found on a dead boy's tennis shoes. the victim was eric middlebrooks, his body left here in a rainy alley. a foster child who rode his bicycle away one night on an errand and was dead by dawn. detective bob buffington saw something red stuck to eric's tennis shoe. >> and i noticed in the flap of the edge of this shoe this tuft of what, to me, appeared to be wool. and that was it. we could find no other evidence. >> back at homicide, buffington showed the fibers to his superiors.
