I think the question most are missing is - how did she end up there in the first place? Given the positioning in front of the wing (and that the other ejected passengers and crew were to the rear of the craft) it seems unlikely she was thrown there in the crash. Presumably the autopsy might shed some light on whether or not she could have escaped down the slide on her own. The third possibility is that someone brought her out and left her there, apparently alone. If that's the case, I suspect the individual is keeping their mouth shut for fear of being sued.
