Sometimes douche-canoes will roll through apartment complexes looking for packages left at doorsteps. Amazon's are especially eye catching, and these assholes know that if it's an Amazon box, then there's more likely than not something decent in there.
If this happens again, I'd advise getting a small surveillance system - just to monitor the goings on at your door. They're fairly cheap nowadays, and police freaking love the ones where the footage is admissible as evidence in a court of law.
