Not to be a wet blanket but I totally agree with crimecurious: I would be shocked if the Judge rendered any decision today. We'll learn some important facts about the case but we won't know the outcome of this hearing.
I don't think there is much doubt that he will transfer the case for trial as an adult but, if for nothing other than appearance's sake, he will take some time to review the reports and deliberate after today's hearing. I'm almost positive these certification decisions are not appealable so he doesn't need to worry about the embarassment of being overturned but, let's face it, he's an elected judge and this may be one of the most high profile cases he may ever get, he will want to rule quickly enough so that people will view him as tough and decisive but not so quickly that anyone can claim he thoughtlessly railroaded a juvenile.
I hear everyone's concerns about cover-ups being behind the secrecy but I really think this is more about an elected sheriff and prosecutor not wanting to give the defense a chance to argue that the local jury pool is tainted. The prosecutor wants to make sure this case doesn't get removed to a distant venue and that it gets tried in his home court where he can get credit in front of his electorate. And who wants to be known as the Sheriff who let Elizabeth Olten's killer walk because he couldn't keep his mouth shut?
