The second edition of this unique one-stop guide features key updates to all the processes and actions involved in conducting major investigations. In a clear and understandable fashion, it explains the processes, procedures and instructions integral to the role of SIO and encompasses all the vital elements for mounting successful investigations. This update sees extra information included on dealing with crime scenes, particularly terrorist-related, handling the news media and using social networking websites to good advantage, as well as the previously uncovered area -investigating the deaths of children. A portable and accessible point of reference, the Handbook condenses ACPO guidance, core doctrines, legislation, and procedures into one volume and provides practical advice, cases and checklists for each stage of the investigation. All stages relevant to the role of an SIO are covered including: initial response; crime scene assessment; evidence gathering; dealing with suspects; and liaising with the media. Context to the procedures outlined is facilitated by case studies, which the authors supplement with explanations and important procedures and processes interwoven with examples. This title is aimed at anyone who conducts, reviews or has a professional interest in major crime investigations, particularly homicide. It will also be of interest to those who perform call-out duties or are expected to take command and control of such incidents, making vital early decisions. It is a must have reference tool for any SIO (or prospective SIO) whether they be at beginner, intermediate or advanced level.
