Amazon.com description: Product Description: This book documents the heroic efforts of some of the nation’s most prolific cold case detectives. In collaboration the authors, these professionals share their insights, skills, and resources, using their most compelling cold cases as illustrations.

The authors examine how cold case investigations differ from standard investigations and why cold case detectives sometimes have success where earlier investigators failed. They also discuss some of the pitfalls of reopening long-unsolved crimes, such as lost or compromised evidence and the difficulty of getting accurate information from witnesses who must rely on fading memories.

Looking to the future, the authors discuss new technology that may someday allow investigators to drastically enhance surveillance videos and create a facial recognition database as accurate as DNA analysis and fingerprints.

Both true crime readers and fellow law enforcement professionals will find the stories and expert insights described in this book to be fascinating and instructive.
