Seriously, where did you find it and when. It might not have been that recent. I'd try to guess who might be Mac geek and like amethyst and backpacks, but I don't know. ClaireBear, Lisa Null, Cindy/Grey, Peter/Joanne. If a persons moving around a lot, they might not notice the computer's gone or they might not know where they lost it or they might think it had been stolen elsewere.
