I think we can be fairly certain that she was the one who ended the assault — especially after she fired close to a dozen rounds at him... The police will obviously wait for forensics to match the bullets in his body. My question is why are you questioning something that every witness has attested to thus far?
INDEED.
My best guess . . . genetics . . . willfulness . . . pride . . . habit . . . but really . . . hard to say.
