Book excerpt: The Nature of 911 Homicide Calls: Using 911 Homicide Calls to Identify Indicators of Innocence and Guilt Abstract This exploratory study examined verbal indicators to critically analyze 911 homicide statements for predictive value in determining the caller's innocence or guilt regarding the offense. The audio recordings and transcripts of one hundred 911 homicide phone calls (fifty innocent callers and fifty guilty callers), obtained from police departments and sheriff's departments throughout the United States, provided the database utilized for the study. This study used a retrospective approach, utilizing adjudicated homicide cases in which the determination of guilt or innocence of the caller had already been proven through the legal system. Since the homicide cases were closed, the study was able to focus on the degree to which the twenty variables were able to indicate the likelihood of guilt or innocence of the 911 callers. The first variable examined is the "Plea for help," which would be expected when a caller uses the 911 emergency contact resource to report a homicide or death. If the Plea for Help is evident, the following sub-categories were also coded and examined: A. Who the help requested for (victim, caller) B. The location of the plea (first communication, later communication). C. The context of the plea (immediacy, lack of immediacy). D. Urgent demand for officer response (present, not present). Additionally, the following variables were also analyzed: Modulation, Verbal Reaction before Dispatcher Introduction, Self-Correction, Extraneous Information, Inappropriate Politeness, Caller's Acceptance of the Victim's Death (with and without relationship), Possession of a Problem, Insulting/Blaming the Victim, Minimization (early in discourse and later in discourse), the "Huh Factor," Repetition, Conflicting Facts and the Caller's Resistance to Answer the Dispatcher's Question. Univariate Analysis and Bivariate Analysis were utilized to study the data. The research results revealed that the presence or absence of sixteen of the variables can indicate the likelihood of the caller's innocence or guilt regarding the offense of homicide.

Download or read book 911 Calls in Homicide Cases written by and published by . This book was released on 2018 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year, numerous 911 calls reporting a death or a serious injury that leads to death are received by emergency communications centers; many of these turn out to be related to a homicide. Interestingly, a small percentage of these calls are made by the perpetrator. These calls constitute the first available evidence in most homicide cases. They are recorded at times of great stress and are the first versions of what the callers purport to know. The ability to develop hypotheses about a caller's truthfulness enhances the police response by objectively informing the process of formulating early investigative strategies. For example, knowing whether the caller uttered any words or phrases considered to be red flags that indicate deception would give an investigator an idea about whether the caller should be interviewed in greater depth. The present study examined 14 linguistic variables and an additional 4 "mitigating" variables in an effort to determine whether any of those variables, individually or in combination, were predictive of guilt or innocence. A sample of 50 calls to 911 centers was selected, including 36 innocent and 14 guilty callers. Five of the variables (Extraneous Information, Conflicting Facts, Incorrect Order, Proximity, and Weapon Touch) were significantly correlated (p

Book excerpt: Kenneth Salter, chairman of the math department at Marcus Rome State University, isn't a well-liked man; in fact, most people despise him. It's not surprising, therefore, when he ends up dead, slumped over in his office chair. All the animosity directed toward the professor makes this a challenging case for homicide detective Tom Warren. His list of possible suspects is long. Much to his chagrin, Warren finds himself teamed up with some law enforcement outsiders. Jim Albright is a math professor and detective wannabe, while his wife, Donna, is a sexy psychologist. Elmo Sherwin is a loveable math genius, but he's as clumsy as he is eccentric. How can these novices help Warren solve his case? He'll soon learn it takes more than crime scene know-how to catch a killer. It's going to take interviews, deduction, and reasoning to make sense of Salter's murder. Everyone sees things differently, and what one person observes could be missed by everyone else. Are you clever enough to follow the clues and construct the argument that points uniquely to the guilty party?

Download or read book The Globalization of Evidence Based Policing written by Eric L. Piza and published by Routledge. This book was released on 2021-11-29 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evidence-based policing is based on the straightforward, but powerful, idea that crime prevention and crime control policy should be based on what works best in promoting public safety, as determined by the best available scientific evidence. Bringing together leading academics and practitioners, this book explores a wide range of case studies from around the world that best exemplify the integration of scientific evidence in contemporary policing processes. Chapters explore the transfer of scientific knowledge to the practice community, the role of officers in conducting police-led science, connection of work between police researchers and practitioners, and how evidence-based policing can be incorporated in daily police functions. The Globalization of Evidence-Based Policing is written for both researchers and practitioners interested in ensuring that scientific research is at center stage in policing. Agencies (including law enforcement agencies, research centers, and institutions of higher learning) can look to these case studies as road maps to better foster an evidence-based approach to crime prevention and crime control. Those already committed to evidence-based policing can look to these chapters to ensure that evidence-based policing is firmly institutionalized within their agencies. Accessible and compelling, this book is essential reading for all those interested in learning more about and doing more to bring about evidence-based policing.
Download or read book CRIME SCENE STAGING written by Arthur S. Chancellor and published by Charles C Thomas Publisher. This book was released on 2016-12-02 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique text has been written as a practical reference for detectives, crime scene investigators, and prosecutors on how to recognize a staged scene and how this offender behavior could be used as evidence in subsequent trials. The book is designed to help those actively engaged in conducting criminal investigations identify the red flags or those common findings at a crime scene that point to the scene being staged or altered and thereby assist the investigative process. The text is not only research based but also includes the authorsf 30-year experience and personal observations in conducting hundreds of different crime scene investigations ranging from homicide and death, burglary and other property crimes, to rape and other sexual crimes. This experience also includes interviewing hundreds of victims and suspects, and conducting investigations from initiation of cases through prosecution. The authors have located hundreds of examples of staging and have included many of them as case studies throughout the text. Many of the case studies presented are based on the authorsf personal involvement in them. In addition to defining and categorizing the various aspects of staging, the reader is also introduced to new terminology describing the different elements of staging based on offender motive and the dynamics of the events. Other major discussions include primary and secondary staging as well as the two subcategories of primary staging: premeditated and ad hoc staging. Staging by individuals other than the offender and victim, described as tertiary/incidental scene alterations, are included as are several chapters on a variety of crimes and how to identify the red flags relevant to them. A final chapter is written especially for prosecutors and offers suggestions and references on how the concept of staging might be introduced in court. A very thorough Appendix provides reviews of many appellant court decisions from across the U.S. and Canada specifically addressing issues of staging.
