So I take the photos aren't clear enough and/or the FBI doesn't have the facial recognition capabilities (read not in the database) to identify these fuckers?

Can anyone elaborate on the scope of facial recognition technologies used by law enforcement? NSA surely has something powerful...

Also - cell towers - they can look at logs for the time period when these guy were on the phone and nail down a list of suspects, etc.

Wonder what their approach is here. Clearly enlisting the public to help is key but I'm sure they have a variety of technologies to find these fucks.
