Sergeant Tyrone Hassel III

I think about that a lot.

I think about the little guy, Tyrone Hassel IV.

Do you want so you can sit in my car with him or whatever?

Yeah, that was probably one of the most difficult parts of working that scene.

The sergeant has a faint pulse as the ambulance heads to the hospital.

Unbelievably, it's the same hospital where Ashanti Hassel, Tyrone's stepmom, is working the late shift.

You knew he was gone?

Sounds like this dude, he's just home from leave for the army.

Back on Colfax Avenue, investigators know it's going to be a long night.

We got a guy shot in the head, shell cases all over the place where he was standing outside.

We really don't have a whole lot to go on.

It was a baffling case to start with.

With three decades of experience under his belt, Sergeant Lanier senses that the answers to those questions will not come easily.

You need a ride, Tyrone?

Nah, I can make it.

I'm heading that way.

When you have a shooting incident, usually there is a lot of people that show up at the hospital.

You want to get there as soon as you can to get some witnesses, family members, just to get initial statements.

It was bad.
