I'm just assuming - but if he shot himself, he probably shot himself in the head. If he pulls through, he will probably have severe brain damage and he may not ever be able to explain his actions.
I mean there are her family members knowing that the video of her getting killed is every where on the internet for people to watch. And the fact that they (the family members) can watch exactly how she died is just..
I think he shot her once, and then once she saw him he continued firing.
Not that part, but I'm referring to the 0:17-0:19 mark (where's she's still interviewing the other older woman). But like MrBeyonceFan said, she probably didn't recognize him or didn't think anything of it.
Hopefully.
That was terrible
