If this guy lived a transient lifestyle (and he wasnt the perp) there is a real chance he would have no idea about the murders or his pictures on the Internet. I can tell your very young but believe it or not there are people that just pass through small towns and these people dont use the Internet or watch the news. He could have been recently down on his luck from out East making his way somewhere warmer, hiking, catching rides when he could, hoping trains etc you need money to be on the Internet and when you are struggling to survive going on the Internet is the last thing you care about. I've met many people like this over the years, just through the grapevine and I'm generally a friendly person who will talk to random people now and then. This is hypothetical of course but I'm just saying some people think everyone knows what's going on in the world.
