America in the 1800s was a very hardworking society. Early in the century, farmers, craftsmen, and housewives worked very much the way they had for centuriesby their own physical labor and the sweat of their brow. The growing industrial economy brought millions of workerspeople leaving their farms and new immigrantsinto the factories and workshops of America, where the work was hard, the hours were long, and the pay was low. Women and children made up a large percentage of the industrial workforce, and conditions were often miserable and dangerous. Meanwhile, a small class of industrialists built vast fortunes. As the century progressed, improved technology, workers rights legislation, and the rise of trade unions helped to alleviate some of the misery of American workers, but for much of the 1800s, the lives of an average workingclass person was one of hard toil, limited opportunities, and the constant threat of poverty.
A flake of skina strand of haira fleck of salivaa drop of bloodeverywhere we go we leave behind bits of ourselves that are as unique as fingerprints. Each cell contains genetic material called DNA, which holds information that scientists can use to learn about the person who left those cells behind. In the past twenty-five years, researchers have made significant advances in all disciplines of science, including the study of genetics. As science has leapt forward, the effect on forensics has been remarkable. New knowledge of DNA has dramatically changed the amount of information available to forensic scientists at the scene of a crime, opening doors that were never open before.

Welcome to the exciting world of forensic investigationthe science of solving crimes. This introduces the field of forensic anthropology, where scientists and criminal investigators use the human skeleton to solve some of the worlds most mysterious and violent crimes. From the nineteenthcentury murderer who boiled his wife in a vat of acid, to the modernday pig farmer accused of murdering more than sixty women, forensic anthropology shows how even the tiniest fragments of bones can reveal the identities of victims as well as killers. From mass-transit accidents to war to genocide and terrorist attacks, this science also pieces together the most scattered and seemingly unidentifiable remains. Using recent finds such as bags of bones in the woods, or the five-thousand-year-old skeleton of a victim of foul play, forensic detectives use the smallest clues, revealing a massive crime-recording device: the human body. See how the dead do tell tales to those who know how to listen!

Real-life crime dramas on television intrigue us with the details of postmortem examinations leading to the arrest of murder suspectsbut how do forensic pathologists, the doctors who investigate unnatural deaths and chilling crime scenes, actually bring criminals to justice? The story lies in the body of evidence. Literally. The human body provides a wealth of scientific evidence that allows forensic pathology, or legal medicine, to help resolve criminal cases and convict even most elusive perpetrators. The human body records the story of a crime in the language of cuts, wounds, and bruises, and in the fingerprints and bloodstains. Forensic pathologists are trained to scrutinize and interpret this evidence in ways no other scientist can. Examining victims remains from the outside in, forensic pathologists investigate every inch of the human landscape to discover when, how, and why the victim died. Sometimes, a time of death is all a jury needs to convict a suspect of murder, and forensic pathologists are experts at uncovering this crucial evidence. Visiting crime scenes, collecting bodies in the middle of the night, and excavating suspicious burial grounds are all in a days work for the sake of bringing justice to victims who can no longer speak for themselves.
