Hey marcherman!
Ah yeah, see my notes about version 1.1 - you unfortunately have a version of the game with a bug, where you don't have the correct evidence screen. However, as you're very near the end, you might just want to push on (just be aware that with the correct screen, the evidence gameplay is generally a bit easier).
I can't do spoiler tags here unfortunately, SPOILERS BELOW

"Rostro Pass (disused)" - the road is disused, suggesting that this could've remained undiscovered for some time.
