Personally, it wouldn't have been such a big deal if the parents didn't talk about their innocence right away(hiring a press agent, and all that stuff) and also they could have co-operated with the cops a little more. Like taking lie detectors, and stuff like that. They were judged in the eye of the public. This guy does look suspicious, people say he's just looking for his 15 minutes, you'd have to be very morbid to say you killed and raped a 6-year old girl, just to get your 15-minutes of fame.
