so in the two hours between the killings - he went back to his dorm, and took this package to the post office?

Fox is calling it a manifesto and calling it a "package". So I doubt it's an email.

They must know it was mailed on the 16th, and that he couldn't have mailed it before the first shooting (too early).

Unless there was an accomplice.
