After their divorce in 2006, Paige was the primary caregiver for their three children.

It wasn't an easy job.

So when Paige Bergfeld disappeared, Sheriff Stan Helke was pretty convinced this mother of three would not leave on her own.

Authorities started by looking at those closest to Paige.

And they quickly learned that Paige Bergfeld had not one, but two ex-husbands.

Her first husband was her high school sweetheart, Ron Bigler.

In fact, for the past few months, the two had been dating again.

Ten years after divorcing her first husband, Paige said she was in love with him again.

And ex-husband number one became the focus of the investigation in June 2007.

When it's learned, he was with Paige the day she disappeared.

Paige and Beigler had their last date at this rest stop, a halfway point between her home in Grand Junction and his home more than four hours away.

When she was driving home later that night around 9 p.m., Paige called Beigler from her cell phone.

They spoke briefly, and Paige told him she'd call him later.

Cell phone records show that Paige was just a few miles from her home when she made that call to Beigler, and that phone call was one of her last.

Paige never did call Beigler back that night, so the next day he tried calling her.

On Saturday morning, two days after seeing Paige, Beigler finally tried calling her at home.

Paige's live-in nanny was taking care of her three children.

And ironically, after Bigler called authorities to report Paige missing, he became one of the first they wanted to question.

Although Bigler was one of the last to see and speak with Paige, those who know him believe he's also one of the last who'd want to harm her.

Paige's friends were far more suspicious about her second ex-husband, Rob Dixon, the father of her three children.
