In this first clip, a friend of Austin's details the scene.

yeah he's still here okay like i mean like coaches have him he can't hurt him okay when you say they have him are they physically holding him down uh no like they're just holding him walking around and in this 911 call you can actually hear hunter metcalf pleading with his dying twin brother oh

Hunter is not the person calling 911 in this call, but you can hear him in the background.

You're going to hear a couple of people, one man saying, staying with me.

Austin's voice is the deeper one.

You hear him saying, come on, come on, you can do it, fight through, as he begs his brother to keep fighting.

It's awful.

So awful.

These two sweet boys who grew up together from the moment they first came into this world in their mother's womb together, holding each other as all little twins do when they're in their mother's womb.

And ever since, and you can hear him because the both were avid sportsmen, tough competitors.

And you can hear him thinking the only thing he can do for his brother is to encourage him to find that toughness, fight through, fight through, fight,

but it was impossible.

It was a feat too great even for Austin Metcalf.

His heart had been punctured with a four-inch knife so deeply and so brutally that the bone behind it had been nicked.

What we weren't shown, according to Sarah Field's

is the body footage, the body cam footage showing Austin on the ground.

This was played in court.

His face turning purple, gray, as Hunter was screaming, oh my God, please, God, please.

That's my brother.

That's my best friend.
