Happened to us last night. One of our party members died in a fight against 3 ogres, and one of the ogres died on top of him. We could highlight his weapon, but it said something like "Target cannot be revived" (if you highlight the ogre itself, it says "Invalid target", so I know I highlighted the player).
However, in our case, we managed to push over the ogre, and then we were able to use the scroll.
