I'm Lester Holt tonight on Date Live.

Every family has its story, but few families have one as dark as this.

I've had so many nightmares about the attack.

I remember like when is it gonna end?

Like just make it stop.

There was a home invasion.

I'm yelling out mom.

I can see her just getting yanked back by her hair.

She said she reached in for the gun.

She fired it.

He's on the floor.

I can see blood around him.

So the story is this incredibly brave mom of her protecting her cubs.

I was very proud of her.

It was such a bizarre set of facts.

Well said, her story fits the evidence.

And I'm just like, oh no it doesn't.

So it's an execution he walks into.

Is that the way you see it?

Totally.

She killed me.

I was defending my family.
