lulz, but I agree with nickerbocker.
If it isn't in there anymore, it has to have went somewhere. Try letting it run for a few minutes while you watch for leaks. If it is leaking and just evaporating off the manifold or something, you should be able to smell it.
As for the washer fluid, I think thats in a plastic jug, and those can have hairline cracks that only leak while you're moving.
