First of all, they have his computer now. The police chief said they were going to ‘talk’ to “everyone he ever knew throughout his entire life.” The fbi is on the case. And just like cho, jiverly voong, and loughner, you will never, ever see the dots connected...unless he was a rightwing critter...which he isn’t.
I thought of Loughner too. Of course that was a federal crime, but they whisked him away from that talkative sheriff in very short order.
