And therefore, it helps corroborate those pieces of evidence.

Well, the only way you can cause that is if you are encephalopathic from either severe disease or if you have spread actually into the brain.

But, you know.

I would argue, you know, the directed behavior of putting on an actual ski mask and going out and committing a crime shows that you're able to put two thoughts together as opposed to just being crazy or acting in an encephalopathic state.

What do I know?

Yeah, if you have direct involvement.

If you have direct involvement of the brain with tuberculosis, you're going to have pretty significant brain swelling, which tends to put a person bed-bound rather than acting in a crazy-like state.

It depends upon, not to get specific, but where the disease is involving the brain, but generally not associated with tuberculosis.

Sure.

So, I mean, from watching the horrible video, you can see that the stab wound was likely to the neck just around the collarbone area.

And in that area, you have several major arteries.

If the blade is long enough, it could certainly have cut the aorta or some of the branches of the aorta, including the carotid artery.

Those vessels carry blood about a half a liter to three quarters of a liter per minute.

So if you can imagine, if that vessel is cut,

you can bleed out probably half of your total blood volume in less than about a two-minute period.

So what they're trying to do is put pressure on that area, or at least they hope they're trying to put pressure on that area to stop the bleeding, but very hard to put pressure on that area because it's your neck, the collarbone's in the way, so it's hard to actually stop the blood from splurting out.

Most times, these wounds are fatal.

It's almost impossible to get this person to the hospital in time.

Yes, because blood flow here, these vessels carry blood at high volume and fast rate.

And so when you cut that blood vessel, it will spurt out.
