Tom Fallis

Ashley's parents had lost their daughter, but they didn't want to also lose their grandchildren, so they maintained a relationship with Tom.

But then, two years later.

Tom, Justin Joseph with Fox 31 News.

An unexpected twist.

A local television news reporter began his own investigation.

Fox 31 Denver's Justin Joseph has been digging into this case, discovering new clues.

How would you describe the last two years?

It's hard to grieve.

In early 2014, Jenna Fox and Joel Ragunden were still convinced that their son-in-law Tom Fallis murdered their daughter Ashley after the New Year's party in 2012.

Why would he kill her?

But the Evans Police Department did rule Ashley's death a suicide and close the case.

And it remained closed until reporter Justin Joseph got a call.

I had a source with law enforcement who called me and said, something isn't right about this case.

Joseph, who is also a CBS News consultant, spent months investigating and interviewing neighbors who had initially spoken to police.

And then in April 2014, he got a major break.

A young next door neighbor, Nick Glover, told Joseph something about Tom Fallis that was not in the police reports.

Nick said he told that to Evans police officer Michael Yates.

And then Joseph reported cooperation of Nick's story.

A sheriff's deputy at the scene came forward two years later to tell investigators that he also heard Tom say he shot Ashley.

Nick's mother, Kathy, also spoke to Joseph, telling him she had gotten a call that night from another neighbor, a teenager named Chelsea Arrigo.
