They knew what high school because it was a slip up. If you knew these guys, they aren't the kind who would just sit there and look at pictures. They had some software running.

As someone who has been a software developer for quite a long time, this statement makes a big assumption.
A good software developer knows it is often far easier and faster to flip through a couple of hundred photos and process them with your meat-brain rather than write a one-off bit of software to do the matching, even if you start from an existing base like OpenCV or whatever.
Having software running doesn't preclude using your brain - first to consider possible heuristics and then to do the types of analysis computers aren't good at. There's a reason mechanical turk exists.
