I don't think the show has explained it, but I think it's something along the line of: If Hulda died and stayed looking liked a troll, then the police who responded would have had an insight into the Wesen world. Of course that assumes that anyone other than Marie or Nick would have seen him as a troll to begin with. Maybe we'll get lucky and they'll explain. Eventually, we have to get out of the "monster of the week" mode; maybe tonight.
