Real-life crime dramas on television intrigue us with the details of postmortem examinations leading to the arrest of murder suspects, but 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.
Who committed the crime? When? Even the smallest of witnesses can tell scientists stories that will make or break a criminal case. Insects and pollen grains help forensic scientists bring criminals to justice. A suspect escapes a crime scene, leaving not a trace of evidence behind - except for the hind leg of a grasshopper, which helps convict him of murder. A thief runs through a cornfield, relieved that no one saw him commit the crime - unaware of the tiny grains of pollen stuck to his shirt. Plants and insects hold clues to guilt or innocence. Evidence from nature is all around us, silently and swiftly leaving fingerprints, unnoticed by even the most cunning of criminals.
The famous Lindbergh kidnapping in the 1930s was solved, in part, through a detailed analysis of the kidnapper's handwriting.

Why are programs such as CSI, Law & Order, and Cold Case so popular? Our culture is fascinated with crime, and these television shows reveal investigators’ procedures and secrets. With so many forensic-based television programs, it might seem that North America’s morbid curiosity is a new phenomenon. The truth is, however, that humanity has always been fascinated by that which also frightens them. What’s more, humans are attracted to puzzles, and forensic science offers opportunities to solve mysteries while at the same time catching the bad guys. Modern media has only magnified the tendencies of previous generations. This book takes a look at the ways this fascination with crime shapes modern news media, television programming, movies, and the Internet. It also provides information on the real-life opportunities for forensic careers. Forensic Science is more than just a cultural obsession: it is a fast-growing professional field. Forensics in American culture will reveal this field’s intriguing mixture of science, mystery, excitement, and justice.
A flake of skin, a strand of hair, a fleck of saliva, a drop of blood - everywhere 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 investigation, the 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 nineteenth century murderer who boiled his wife in a vat of acid, to the modern day 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!
Television programs and feature films present criminal psychology and profiling as a blend of psychic visions, supernatural intuition, and evidence analysis. The reality, however, is quite different. Using true-crime case studies from history and the present, examples from current and former FBI profilers and informative sidebars, Criminal Psychology & Personality Profiling explores the many roles and responsibilities criminal psychologists and profilers fill as they support other professionals in addressing crime and its consequences. From crime-scene analysis to offering expert testimony in court, these behavioral scientists offer an understanding of crime, the criminal mind, and those affected by crime.
Crimes happen every day all around the world. Sometimes, criminals think they have taken every possible precaution to avoid capture, but they are often mistaken. Every crime leaves a trace, and forensic science has evolved to find the tiniest bits of evidence imaginable at a crime scene. Mark & Trace Analysis gives readers some insights about the tricks and techniques used by forensic scientists and crime-scene investigators when evidence is scarce. Criminals always leave a trail. The trick is finding it.
Charles Darwin's On the Origin of Species changed the way we understand the beginnings of life on earth. Darwin's ideas challenged people to think differently, to question long-held beliefs, and to explore a new field of scientific discovery. As a young man, Darwin worked to join the priesthood, but his life took a turn toward science after he joined a government mission to South America and the Pacific. Darwin's work on the trip pushed him to come up with new ideas about life and nature, including his famous theory of evolution.
