I don't know. I don't think they should sue either but I see why they are. They probably feel really violated, even though it wasn't the hotel's fault. I know I would. I would have a hard time drinking water for a really, really, long time and they probably don't know how else to get peace of mind.
Becasue this is where I live I am well updated on this case. Just so everyone knows there is a bunch of video of this girl walking around the hotel by herself acting very irratic. We were informed of her dissapearance quite a while before she was found. I have no idea but I'm going to guess it was suicide. But again, I have no idea.
