I'd say that someone shot her, and then came in to make sure the job was finished.
The splatter pattern is all off though, and that pool of blood is too big for the shot to have come from her neck.
Judging by the pool of blood in her lap, I'd say that she was actually stabbed in the groin. I'd say she was probably carrying the man's child.
He left the door open while he was stabbing her, and had the peace of mind to close it afterwards, suggesting that he's killed before, and that it was more than a crime of passion.
There's a high chance that the phone booth was a meeting place they had, her waiting there and him calling. I'd say that means that he has a family, and doesn't want her calling him. He probably called her to lure her into the phone booth so he could get rid of her.
She probably just wanted the man who knocked her up to take responsibility. tsk tsk, the lengths some people will go when their way of life is threatened.>>11981053
Two people won't fit in that booth. I'd say that's her blood.
There's no exit point because the bullet was probably a hollow point or something like that.
