There's a lot of mountain folks around here.

The Central High Bobcats are a big deal here, and it's just as big of a deal to be on the cheerleading squad.

In the fall of 2014, Emma Walker was 14 years old.

Going into high school, being a freshman cheerleader, was that a big deal for her?

She had done competitive gymnastics as a young child and then competitive dance.

When she tried out for cheerleader, she was the only freshman that made it.

So she was very tickled with herself.

People described Emma as bubbly and fun-loving and positive.

I think it was really effortless for her because it's kind of who she was in a way.

So before long, freshman Emma is going out with a junior on the football team.

Number eight, Riley Gall.

Riley Gall and Emma Walker were just this sort of quintessential high school couple.

What did you think right away of this new boy that she was smitten with?

A boy next door.

He came in very polite, very nice in the beginning.
