I'm trying to picture the scene but it's tough.
Is it a crowd around her watching (implicitly acknowledging her) or passerby random people on the background? Or do you mean a crowd watching but not reacting in any noticeable way to the gore?

About background context, do you want it to be some random exhibition on a park bench, stage performance-exhibition, a casual train interior shot?
I'll try to add as many elements of what you suggested as possible
