She wouldn't be tested if she was yelling and hollering?
Well,I was in administration,so I can't speak with any enormous degree of credibility but I did see a lot in my 20+ years there.
My hunch is that she would have been seen as having a reaction,perhaps normal,perhaps abnormal,to having suffered an important mental (and,perhaps,physical) trauma.
If they found track marks on her,or dilated (or constricted) pupils or smelled alcohol on her breath they *might* have done a toxic screen her.
But keep this in mind: when a woman presents to an ER claiming to have been raped,the medical staff pretty much assumes that she's telling the truth.These staff members are much more comfortable cooperating with the police and prosecutors than with defense lawyers...if ya catch my drift.
