Review of "Analyzing 911 Homicide Calls, Practical Aspects and Applications."
Susan Adams, PhD.
Having been a homicide detective in Chicago for 19 years, I have come to realize that I could have greatly benefited from the information provided in this book, from my very first case.
Prior to the publication of "Analyzing 911 Homicide Calls, Practical Aspects and Applications," I had attended several of the lectures presented by Deputy Chief Harpster, on 911 call statement analysis (Is The Caller the Killer?), which provided a hands on approach to 911 call analysis suitable for detectives, investigators and 911 call takers and dispatchers.
This book is an excellent companion to the lectures, but can be used by itself. It should be a required read for all in any aspect of Law Enforcement and prosecutors.
Information learned from this book can be applied to almost any type of investigation, where knowing if a 911 caller who is reporting a crime is being truthful or deceitful and then steer the investigation in the correct direction.
Being able to establish the veracity of a caller reporting a child (or adult) missing, will allow the investigators to concentrate their resources on finding a bona fide missing child or person, as apposed to mobilizing a massive search party and expend valuable resources, when one is not needed. This may resolve a case in an expeditious manner.
Valuable time may be lost if the focus of an investigation is intentionally misdirected.
By utilizing and referencing the "COPS Scale," developed by Deputy Chief Harpster and co-author Dr. Susan Adams, which is included in the book, a 911 call taker, or tele-communicator can provide vital information to the first responders assigned to an investigation, before they arrive on the scene.
The "COPS Scale," is based upon years of research and analysis of over 1300 actual 911 call recordings conducted by Harpster and Adams, and the conclusions of their research have been validated.
The reviewing of 911 tapes and /or transcripts should become a common and standard practice in any death or homicide investigation, but should not be limited to just those types of investigations.
Investigators should know that the presence of the 911 call is often the only statement a suspect will make implicating themselves to a crime and it should be used to refute any subsequent statements made during the course of the investigations.
"Analyzing 911 Homicide Calls, Practical Aspects and Applications," is an invaluable resource and should be in every investigators personal library and in every 911 dispatch center, nationwide.
