Yes that is true. But Boulder is very liberal, and this confession might not meet their standards at the DA's office. It certainly doesn't meet my standards as a confession, especially since he said something like, "things aren't as they seem" at the end of his interview with AP.
He said he was in the basement, but not which basement. He said he was with JonBenet when she died, which could mean something else entirely to an individual with mental problems. He said he wasn't innocent, which could mean anything. But, he said no comment to all questions about the actual murder or entering the house.
I have a feeling he is going to end up saying his statements were coerced by the Thai police, who have already admitted to dealing off the bottom of the deck. He may not say anything else after he gets to the U.S., although I think enough would come out through research of his life to show whether he did it or not.
He did have a Jaguar in 1997, and a Jaguar was seen in the neighborhood around the time of the murder. So, there is still hope he's the guy, but not much really, at this point.
