So important evidence clarification right now.

It has been clarified that 9mm spent shells were recovered inside the house.

That's a 9mm spent shell.

So what does that mean?

They did not specify how many.

So we don't know how many.

But what that tells us, this is a nine millimeter spent shell,

and what you're looking at is a firing pin impression, which is also unique to the gun

that this spent shell came from.

In addition, this is a picture of the spent shell, but the extractor marks also unique to the firearm that fired this.

And we don't know how many spent shells.

The other thing I said to Professor Mike was, this is beautiful.

Because when you load a semi-automatic handgun, you must load into a magazine one at a time.

And however big that magazine is, whether it holds 10 rounds, nine rounds, 12 rounds, the only ones that get 15 rounds are law enforcement clips.

They're illegal anywhere else.

But guess what? The person that loaded

that semi-automatic put those rounds into the magazine potentially could have left his or her

DNA on the side of those cartridges. So there's another investigative tool that investigators have that potentially could

identify the person or persons that did this heinous crime. And you can see here's a better picture

here for those that aren't that familiar. You could see firing pin impression extractor marks.

Again, I don't want to get too much into the science of

ballistics but all of these things uh are unique markings on the spent shell and then there's a
