Blackstone's Senior Investigating Officers' Handbook is designed specifically to meet the quick-reference needs of any officer conducting a serious investigation. The only portable step-by-step guide to the processes and actions involved in the role of a Senior Investigating Officer (SIO), it explains all the relevant procedures and instructions integral to the position in a clear and accessible style. Now in its fourth edition, this Handbook takes you through all the stages inherent to an SIO's role: from management and leadership, decision making, writing policy books to the initial response and crime scene management, conducting searches, applying investigative strategies, managing victims, suspects and witnesses, family liaison and conducting death investigations and sudden infant deaths. Whether you conduct, review or take a professional interest in major and serious crime investigations, this title will be an invaluable resource. Commonly referred to as the 'must have' reference book, it is a highly practical tool for any SIO or prospective SIO.
