Rev. ed. of: Fundamentals of criminal investigation / Charles E. O'Hara and Gregory L. O'Hara. 7th ed. c2003.

Although the present edition continues to focus on operational effectiveness in the essential missions of investigative work, it has maintained its emphasis on the observance of the rights of the suspect and the accused. Throughout the text a theory of investigation is developed. A statement of principles in the early chapters is related to the investigative procedures described in the later parts of the book. The concepts of 'information' and 'instrumentation' have been broadened to include a discussion of federal data banks and the applications of computers to investigative problems.

This review guide is designed to help students learn the information presented in O'Hara's Fundamentals of Criminal Investigation. Gregory O'Hara's study guide has been revised and restructured to complement the eighth edition of the text. For each chapter you will find a list of key terms and multiple-choice questions. It is recommended that students first carefully read the chapter noting important points and information, then review the key terms and return to the text to clarify any unfamiliar topics. When confident of your understanding of the key terms, proceed to the questions. Most questions are restatements of information in the chapter. Some, however, may require students to apply the chapter information to derive the correct answer. Test your understanding of the material by trying to answer the questions. Correct answers can be found in the back of the study guide. For questions you answered incorrectly, return to the text and review the appropriate information. Through this process of review and self-testing, students can increase their understanding of complexities of the criminal investigation process. This guide is an excellent companion volume to the bestselling textbook and will be useful to students who are reviewing the important elements of this discipline in other criminal justice texts.

Aimed at the busy professional who aspires to become certified in the field, Criminal Investigation for the Professional Investigator details essential techniques a trained investigator will be called upon to perform during the course of a career. The book is authored by a veteran of the NYPD who went on to launch and operate two successful private investigation agencies. It covers crime scenes, death investigations, the art of interrogation, and specific criminal investigations. It also provides important strategies for making arrests and testifying in courtrooms, details the most effective investigative tools to use, and explains the role of criminal defense investigators.

This text in the area of civil litigation investigation continues to fill the need that has long existed for a general reference work on techniques, procedures and practices in the field of legal investigation.

There are over 400 such case citations in this revised edition. Included are discussions of the law of evidence, interviewing witnesses, forensic photography, and investigation reports. A section on professional ethics has been included and an entire chapter has been devoted to criminal defense investigation. Many new illustrations have been included in this new edition. Investigators who must gather the facts of any occurrence, whether a tort or a crime for eventual presentation before a court or other tribunal should find this book a valuable aid.
