An uncanny calm settles on the scene. The blaze is out. A soggy, sooty mess remains. Most of us wouldn't have a clue where to begin, yet fire and explosion investigators know precisely where and how to dig in. Other books in this series show that documents, fingerprints, a stray hair, fibers, bullets, tool marks, blood spatter, SNA, cigarette butts, insects, or even a simple candy wrapper can provide clinching proof in many legal cases—but fire and bombs destroy these bits of evidence. What clues can forensic scientists possibly glean from rubble and ash? Using real-life stories as examples, Explosives & Arson Investigation explores the world of fire—and bomb-scene investigation. From first-on-the-scene priorities to collecting and documenting evidence to lab analysis and its procedures, then finally assessing motive, this book reveals basic fire characteristics, what investigators look for, how they process what they find, the meaning of specific clues, and common motives—all while highlighting various forensic careers.
Have you ever been laughing one moment—and crying the next? How about so angry you could throw something—and then suddenly burst out laughing? All of us have experienced mood swings like this, and they're even more common during adolescence. Rapidly changing emotions—from contentment to irritability, anger to despair, euphoria to despondency—are common occurrences during your teen years. What causes these shifts in mood? The sources vary, but for most teens, two main agents are involved: brain chemistry and life changes. The same hormonal activity that brings about the body changes teens experience also triggers changes in your brain. At the same time, your relationships with your family and friends are changing, you have more responsibilities and freedoms than ever before, and you face a whole new set of pressures. All these things can turn your life into a series of emotional peaks and valleys. But there is hope. This book will help you understand what's happening to you—and it will offer practical coping mechanisms. Don't worry. You too can survive the roller coaster!
"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 day's work for the sake of bringing justice to victims who can no longer speak for themselves.
