The Boulder DA mentioned that Karr lived in Colorado in her statement. However I can not find written confirmation of that.
Also breaking: one of the reporters at KOA radio, along with someone from law enforcement, did a search for John Mark Karr in the sex abusers database. They weren't able to find anything, which is a bit odd.
I don't tend to associate second-grade teachers with "drifters". Not impossible but I'm guessing there's a lot more to this if it adds up. I'm also just a little suspicious of who might be tipping this off.
I also think Patsy's death is not incoincidental in the timing of the arrest.
