#1) When the mission begins, go up to street level and go to the left, where you'll find some stairs to some higher ground. To your right is a building and there's a doorway where you can get inside. Go up the stairs until you get to an open doorway, so go inside. There is a Weeper inside, and the Charm is next to a dead body in one of the side rooms.
#2) When the mission begins, go up to street level and go across the walkway right there. When you cross, go to the right and go inside the building you can go inside there. Note that there are a lot of Weepers on the bottom floor, to your left, if you enter from the front door. On the third floor is where you'll find the Bone Charm, right by the shelf with the two Processed Whale Oil items.
