Likely he did the "I'll show her." thing and tossed his mind through the top of his skull.
(Actually, probably the best outcome. Would mean that he wouldn't stalk anyone else.)
Who knows? If he did the "I'll show her" thing, I never heard about it. But it was quite a relief when he finally disappeared. I was pretty paranoid for awhile, and I didn't own any firearms at that time. Did I mention that this was a loooong time ago?
