3. Dark Side of the Mesa

In the high desert, on the Rockies western slope, the Mesas tower over the town of Grand Junction, Colo., protected from the outside world. But on June 4, 2002, Grand Junction saw the unearthing of a shocking secret at the local landfill. The decomposed body of 34-year-old Jennifer Blagg was found wrapped in a red and black plastic tent. Jennifer and her six-year-old daughter, Abby, had been missing for seven months. Correspondent Susan Spencer reports.
