America has long had a reputation as the most violent and murderous of modern industrialised nations. Even though violent crime has dropped in recent years, the murder rate is still very high. Since the beginning of the 20th century, U.S. society has undergone profound changes, and technologies have advanced, but the motives and methods for murder and escaping the "long arm of the law" have kept pace with these changes, often capitalising on available technologies. In addition, as the century progressed, the media would become an integral part of murder in America, helping investigations, glamorising murder, and bringing it into people's homes on a daily basis.Here, the author examines the changing face of murder in the context of societal changes, and traces the advances in investigative techniques and technologies. Each chapter offers vivid accounts of the most notorious and representative murders for each time period, focusing especially on those murderers who have had the edge on their pursuers, even escaping detection to this day.Beginning at the turn of the century, the author details one of the most notorious cases of the day, in which a jealous woman poisoned the wife of her lover. The book ends with the still-unsolved Tupac Shakur murder case. Taking readers through the various developments in methods of murder, and the techniques used to capture the criminals, the author provides a fascinating overview of the way murder has changed through the decades and how law enforcement has kept pace. This insightful book sheds light on both our fascination with murder and on murderers and their nemeses over the last one hundred years.
