That could very well be true.I think that's why you see warnings today on nail guns that say "do not shoot nails into your head".But if she can sue Duke,it would be in addition to whatever she could get from the kids and/or their parents.
She can sue anybody she wants to, but whether she wins is another question. In the possible case of suing Duke because they owned the house, she would have to prove that the rape occurred and that such an act committed by the specific boys was forseeable.
This would be one of the main reasons she picked Dave Evans - he lives there, he has a previous offense for drinking or peeing or something rowdy like that (I forget at the moment what it was), and he's a team captain. These facts will be used to put Duke on the hook, but, again, she would have to prove she was raped, and I don't think she can do that.
