Mystery Surrounds Death of Colorado Mom

Investigators say they know Paige Birgfeld was murdered, they just don't know how she died.

KKTV 11 News has learned that a team of cold case experts is trying to figure out what happened to her.

The Grand Junction woman reportedly led a double life as a devoted mother and as an escort for hire.

Her remains were found last year.

Investigators say they have a suspect, a man who was a client of her escort service, but they haven't made any arrests.
