Mop Men: Inside The World of Crime Scene Cleaners

A curator for the Smithsonian Museum of Natural History, Doug Owsley painstakingly rebuilds skeletons, helping to identify them and determine their cause of death. He has worked on several notorious cases – from mass graves uncovered in Croatia to the terrorist attacks on the Pentagon – and has examined historic skeletons tens of thousands of years old. But the discovery of Kennewick Man, a 9,600-year-old human skeleton found along the banks of Washington's Columbia River, was a find that would turn Owsley's life upside down.
