Ripped from today's headlines, Unsolved is the first ever book to examine the sacrifices made by American's heroic law enforcement officers who were murdered while their killers escaped justice­. Left behind are devastated loved ones and a law enforcement agency hunting down the assassins. Building on years of comprehensive nationwide research, Bultema, a former LAPD cop, puts a story behind some of the names etched on police monuments across this country. Law enforcement officers make their living fighting crime. The death of an officer killed while on duty presents the most heartfelt crisis a department can face. Agencies make it their highest priority to solve the case and bring the murderers to justice. But it is not a perfect world and sometimes, they are not successful. Unsolved: Cold-Case Homicides of Law Enforcement Officers brings attention to this national tragedy. Building on two years of comprehensive nationwide research, Unsolved includes information on each fallen officer, his or her department and in many cases, an in-depth account of the murder. Unsolved is a touching tribute to these courageous law enforcement officers. Written by historian and former LAPD cop James Bultema, he is an author who understands policing in America. He is the author of the acclaimed books, Guardians of Angels: A History of the Los Angeles Police Department and The Protectors: A Photographic History of Police Departments in the United States. Current LAPD Chief of Police Charlie Beck and former New York City Police Commissioner William Bratton thought so much of what Bultema had accomplished that they each wrote a foreword for these histories. For his new book, Unsolved: Cold-Case Homicides of Law Enforcement Officers, Bultema has compiled the first comprehensive national list of unsolved cases, including information on each fallen officer and, in many cases, an informed account of the officer's murder. Unsolved is a touching tribute to these courageous law enforcement officers.
