Absolutely.

His cell phone is going to be pinging off cell sites all along that route.

And if you look at it on a map, you can trace his route.

He's also probably having to stop for gas, bathroom breaks, whatever it is along the way.

So he left a footprint, he made purchases, he got food, he did something along that way.

I don't know if there's any toll roads there,

but it's almost impossible to drive 300 and something miles across America without leaving a digital footprint and probably CCTV coverage from a variety of different places.

Understood.

Thank you.

Well, Nancy, this right here is a nine millimeter round.

The top part is the bullet.

And the back part is the casing.

Now, you can get DNA off this casing by fingerprints and sweat and whatever else they have on their hands when loading the weapon.

So this is how you load magazine right here.

And also, there are certain marks that are left on the casing after the round is fired.

Now, this is a pistol that this round can be fired from.

The bolt goes out the front and the casing is ejected out of the side.

Now, the firing pin leaves a mark on the back of the casing, which is unique to the weapon.

Then the extractor leaves scratches on the casing, which is also unique to the weapon, and the ejector leaves dents on the casing.

Now, all these marks can be traced straight back to the weapon it's fired from, and that could link the suspect to the gun.
