(NBC News) — On Friday’s “Dateline,” former hockey player, Tom Clayton, discovers his wife Kelley Clayton murdered in their home, when their young daughter says she saw a robber at the scene of the crime, the killer’s true identity turns out to be far more complicated.

Here is a preview of Andrea Canning’s report:

Kelley came home to visit often enough, including Christmas of 2003. By then, Elmira had a new attraction: A minor league hockey team.

KIM BOURGEOIS: My mom, my sister and I were at a hockey game, an Elmira Jackals hockey game. And this player gets checked into the boards, and his helmet comes off, and all three of us were like, “Wow. He’s pretty cute.”

“He” was Tom Clayton. He served as the Jackals’ “instigator” — the guy who starts fights. When he and Kelley locked eyes that night, it was game over.

KIM BOURGEOIS:  She met him that weekend. She met him that weekend.

ANDREA CANNING: She met the bad boy.

KIM BOURGEOIS: Yes, she did.

ANDREA CANNING: Was it instant for them?

KIM BOURGEOIS: Yes. It was.

They were married about two years later. A few years after their wedding came the kids. Almost 10 years into the marriage, Kelley still gushed about her Tom.

GREG MILLER: She was just talking about, “He’s the greatest guy. I mean, I hit the jackpot with him.”

Watch Friday’s “Dateline: The House in the Woods” at 10 p.m. on NBC4.
