I believe so. He'd notice the corpse as in the last game, but I'm not sure what his response would be (In the last game, it's ridiculous how they could detect you if you were watching the body. You kill a guy, wait for his wife to come, she calls a guard, you watch them arguing then they both look at you even though you are sneaking and out of their point-of-view.). I do hope they fix those last game's bugs, since there were many associated with that, and the NPCs seem to improve in this game. I think, yeah, he won't "sense" it. He'll find the corpse or notice he's gone and look for clues to that (Walking around town and outside city walls perhaps, looking for his brother) until night time, then, you know, he'd then tell the guards, which would roam around 'till they were pretty sure he's gone. Then they'd change their formation - Stay more focused on the area the person went missing/was found dead. That's my theory anyway.
