This guy is shown that he's obsessed. It's possible that he is the killer and this obsession started before her death. He could very well have gained information about the family. He could even have sneaked into the house on more than one occasion. He might have been familiar and comfortable there. It's all speculation until we get the DNA results.
I agree, but they need proof he was in CO in 1996 and not elsewhere as well.
I just Googled JonBenet Ramsey, and searched within those results for "autopsy". It's no big secret.
Indeed. However, what if the DNA results are inconclusive? Can't convict a guy on a string of he-might-haves. There's a ton of questions the authorities are going to have to answer, DNA or no DNA, before they could even plan to bring this guy to trial.
