That's pretty nasty, and sad for the woman who died. Must have been dreadful for her family and co-workers to know she was missing for so long, yet her body was trapped within the building.
And I can't believe the British Woman describing the water.
Who sees a shower run black liquid for a moment and then stop and think that is normal and not complain?
I can understand as a tourist in expecting the water to taste different, but it coming out black?
A bit of common sense, surely. That's not normal regardless of where you are in the world.
