"I'm sure a plausible liar could persuade me that there was a reason not to give me facebook ("oh, hey, my mom is on there, and she'd ask me questions about all the guys I keep adding" would probably work on me) or other interactions."

Not to be too pedantic about a hypothetical, but that would give away his ulterior motive a whole lot sooner. I only quibble because there are a thousand ways that modest technology use could snag someone or raise red flags. What if someone had called him on his phone while he was hanging out with this guy? "Oh I'm at the corner of x and x hanging out with a new friend". What if he took a picture of that guy? What if the occasional GTA session and hooking up with dudes on hook-up sites sublimated a lot of the killer's darker urges? Or what if, in a more connected world a lot more accepting of gay people, he just moved to Maine and bought a house with a boyfriend?

I'm sure we can go back and forth about a lot of things like this, but the bottom line is that there has been a massive reduction in violent crime in the last decade or so; I think technology has been a major factor.
