I've got a vivid imagination.. if I say that, nobody's going to ask how i got this idea, right? Okay, let's just try it anyway. All hypothetical, people!
The situation is as follows:
In Miami, California a man (let's call him J) rapes and brutally kills his daughter's girlfriend (we'll call the daughter E). He used his daughter's ornament knife he stole from her apartment but it already had E's fingerprints on it. The cops think it was E who killed her girlfriend (fingerprints on knife). They find out it was actually J because of some skin under the vitim's nails. E goes after J, with the intention of killing him but has no weapons on her, beats the crap out of him then when the cops find them J somehow manages to hold a police officer as his hostage (I could explain the whole thing but it would get too complicated). FYI, they're in an apartment building, two stories up. E gets the cop free and pulls J down with her through the window (again, I could explain but this is all hypothetical). J dies on impact but E's still alive.
I know they'll probably still arrest her for assualt and battery but attempted murder too? Or does the fact that she sort of saved the cop help her case?
I don't know if it changes anything, but E had a crappy childhood, her parents never paid any attention to her and she has killed before (accidentally) when she was a teenager where she did a few years for.
I hope someone can help me with my question.
Thanks in advance

Sorry.
