As I understand it, Karr has neither been indicted nor charged with the crime, yet. To be indicted, the DA in Boulder would had to have been conducting a grand jury investigation into him. As far as I know, that is not the case.
Then, in that case, and in the context of my discussion with Sacajaweau, nothing (no information) is really 'sealed' in a formal sense. I had been suggesting earlier that locating someone in Boulder would be easy if they had used the usual things, like credit cards, reservations, etc. If he didn't it would be hard to pin him there (maybe a witness?). I'm wondering if the DA hasn't found something in the commercial records that shows he was there? Maybe he used a target card, or maybe some security camera caught him. Of course, being as old as the case is, not all these records will survive. But the cc and bank records would and I don't know how smart he was about NOT using them.
Come to think of it, I remember that. There was a Grand Jury hearing but they returned no indictment. The housekeeper was called in and tried to write a book on it but they said she couldn't talk about what she said to the GJ b/c no indictment was returned.
