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.
The digital age we entered in the twenty-first century has rapidly become an age of digital crime. Cyber crimes like spoofing, phishing, and hacking are on the rise, and computer forensic technicians are on the case. Even traditional crimes like murder, fraud, and child abuse can be both facilitated by computers and solved through computer investigation. Computer Investigation helps readers understand how cyber crimes are committed, and how investigators help solve them and bring the perpetrators to justice. Readers will also gain a few tips for protecting themselves online and protecting their computers from intrusions and hacks.
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.
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.
The famous Lindbergh kidnapping in the 1930s was solved, in part, through a detailed analysis of the kidnapper's handwriting. Other criminal cases, such as selling phony manuscripts, forgery, and fraud can be broken with detailed analyses of handwriting, typewriting, photocopied documents, and the inks and papers used on documents. The science of analyzing documents has been growing for more than a century. In this book, readers will learn how to document analysis has helped solve various crimes, from kidnappings and famous forgeries, to bombings and other violent crimes. Readers will also see how document examiners present their findings in court. Crime leaves a paper trail, and document analysis provides the techniques for following that trail.
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.
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!
