Book excerpt: Solving a cold case is extremely difficult and many are left unresolved. In this book, retired NCIS Special Agent Joe Kennedy details the methodology he created to solve cold case murders. He offers an in-depth, behind-the-scenes look into why cases go cold, how they are investigated and what is needed to successfully resolve them. Author Kennedy shares his motivations and the lessons he has learned while solving these challenging cases. Also examined are cold cases where other detectives have successfully implemented Kennedy's methodology. Many books delve into the perspectives of criminals who commit murder, but this text takes a fascinating gumshoe journey into the mind of a cold case detective and his passionate search for the truth. Helping law enforcement solve cold cases brings justice and resolution for the victims and their families, and this book provides detectives and true crime enthusiasts the tools to investigate cold cases in their own communities.
