ARRRGGGGHHHHHHHHHH, indeed. Unless they strike again, I doubt that we'll ever catch them, since the data from our security cameras is so totally unhelpful. :( I've no idea what we did to tick someobody off so badly, but the repetition cetainly does make it seem like something more pointed than just a random "prank."
On a more positive note, the computers haven't had any more problems since Tuesday. :)
