GRAND JUNCTION, Colo. -- Family members and volunteers have resumed the search for a missing Grand Junction woman nearly a year after she disappeared.

Thirty-four-year-old Paige Birgfeld was last seen in late June. Her father, Frank Birgfeld, and about a dozen volunteers returned over the weekend to several sites they searched last year to see if they missed anything.

"You just see this vast territory and you wanna say, where do I even start?" Frank Birgfeld, Paige's father, told KJCT.

Frank and others have been on countless searches looking for the missing mother. He won't say he's confident he'll find her. But he said he can still hope.

"I wish I hadn't had to learn the positives this way, it would've been better in a book. But there are a lot of positives," he said.

Birgfeld had three children and was divorced twice. Friends and family have described her as a devoted mother who sold kitchen products and held other jobs to support her three children.

Authorities said Birgfeld also had an escort service, a discovery that surprised many who knew her.

No arrests have been made.
