Book excerpt: Two National Forensic Science Institute administrators invite readers into what the Washington Post calls "the Harvard of hellish violence"-the only hands-on CSI school of its kind where students are trained in burial recovery with actual human remains. With exclusive access to a world normally off-limits to the public, this is the first book to go behind the scenes of the ten-week course that discloses the uncensored realities of burial exhumations and the fascinating art of forensic investigation.
