I am certain that NYPD and the FBI are doing incredible work. However, the shooter had a good head start for openers. Also, I've been thinking: if he had one fake ID, who's to say he didn't have one or two more? I don't think it will take LE long to figure out who he is. Figuring out where he is could take a bit longer. One other late night/early morning thought: It might be easy to get a fake domestic ID. (I've never had one, but some say it's not that hard to get one.) But getting a fake passport could be far more challenging. Again, this is not my area of expertise. At first, I thought oh, he's on the first plane out of the country. Now, I am not so sure. He could have taken up residence in Arizona with his other fake ID and changed his appearance. JMHO.
