Why do you think he killed Emma?

And so...

Bradley, you are not Emma's hero.

You ended her life.

No punishment will ever bring Emma back, but what helps is knowing that you can't do this to anyone else.

What do you want to see come out of this that might help someone else?

If your boyfriend or girlfriend is telling you you can't go there or what to wear or who to hang out with or who to talk to, that it's not okay.

And I think when they become quiet and withdrawn, it's a big sign too.

It's not just bruises.

It's emotional and controlling.

Riley Gall appealed his sentence.

Three years after his conviction, he was back in Knox County Criminal Court to request a retrial.

But the judge said no, since there was no new evidence, and the state Supreme Court has since rejected any further consideration of the case.

Riley remains behind bars, serving a life sentence for the murder of Emma Walker.

He'll be in his 70s before he's eligible for parole.

I love you so much.

The Walker family finding comfort in unexpected surprises Emma left behind.

And you didn't know she put this on?

That's their thing.

Very cute.
