I have two guesses: broken water pump or leaking coolant tank. Look under the rear trunk carpet to see if you find coolant. If so, suspect leaking tank. This may be a wrong conclusion, however, if the overheat caused coolant to overflow and saturated the carpets. Sounds like that didn't happen given the cap was dry when you first looked. Of course a broken hose or hose clamp could be the culprit, but a successful refill would argue against that. So I'm thinking water pump
