Is JonBenet's Killer Still at Large?

With the latest news on the JonBenet case, with Karr being picked up for her murder, there are a couple of things that just don't make sense;

1) The time Karr lived in Georgia, JonBenet was only 1...how would Karr known the family and be obsessed with someone who hadn't entered the pageant circuit?
2) Karr's ex says that he was with her at the time of the murder...seems to me, that a spouse that is absent at Christmas time would be a red flag for something that was going on. IF that is the case, then why wouldn't have anyone put 2 and 2 together years ago?
3) How come nothing has been released about how Karr knew the Ramseys'?

I believe that Karr is merely looking for his 15 minutes of fame. Someone that is that engrossed with a case, and the case of Polly Klaas, only to become entangled in it to satisfy a need of being a celebrity. There may be more to it, such as JonBenet's parents are somehow involved in the plot.

Don't get me wrong, I think Karr is a whackjob, at best, but the pieces just don't add up. Was there a connection between Karr and Patsy and/or John?? I don't think that it's all as rosey as the news makes it out to be. The case being "solved", after 10 years, raises too many questions to be true.

If the timing of the "confession" isn't coincidence (2 months after Patsy dies), then who knows.

I don't think this case is solved...something still doesn't smell right, and Karr is seeking infamy, in a sick and twisted way.

I hope they catch the real killer, and if it's Karr, then there are questions I am sure we would all like to see answered.
