I found, On Call: Case FIles from a Career in Homicide - What Every Investigator Should Know to be an accurate and engaging behind-the-scenes look at how homicide cases truly unfold. The author provides clear and detailed descriptions of each phase of an investigation, from the initial callout to the final court sentencing. This book not only captures the realities of the job but also serves as a valuable resource for investigators at any stage of their career.

On Call: Case Files from a Career in Homicide is a comprehensive look into the life of a homicide detective and the unfolding of case details from the moment a death scene call-out is received to the resolution of the case in court. Ret. Detective Bocock presents the case details in a manner that is compelling, thorough and educational while maintaining an unbiased approach. His case studies highlight the complexities involved in homicide investigations and the integration of detective work, forensic analysis and legal proceedings and how it all culminates in court. This is a book that appeals to experienced law enforcement personnel as well as avid true crime readers.
