Promoting Effective Homicide InvestigationsThis book aims to improve homicide investigations by examining current agency investigative practices and relatively new investigative procedures that may produce more effective investigations.

CALL FOR ACTION
In 2006, the Police Executive Research Forum (PERF) hosted two conferences addressing violent crime: the “Promoting Effective Homicide Investigations” (May 25 and 26) and the “National Violent Crime Summit” (August 30). Both were instrumental in understanding violent crime in the United States, as well as national and local initiatives to reduce it.

The primary goal of this document is to improve homicide investigations by exploring law enforcement agency practices and examining relatively new procedures that may lead to more effective investigations.

The Federal Bureau of Investigation’s (FBI) report of 2005 crime data showed a 2.4 percent nationwide increase in homicides from 2004.

The FBI’s preliminary numbers for 2006 indicate a continued upward trend in homicides in cities across the nation. For example, during the period 2004 to 2006, homicides increased by 38 percent in Cleveland.

Other cities with significant increases in homicides in that period include Cincinnati (41 percent), Houston (37 percent), Las Vegas (16 percent), Memphis (39 percent), Newark, New Jersey (25 percent), Orlando (188 percent), Philadelphia (22 percent), and Seattle (25 percent).

In light of these increases, police agencies not only need to increase their efforts to prevent homicides and focus the public’s attention on the violent crime problem; they also need to adopt best practices that can increase the effectiveness of homicide investigations. ...

About the COPS Office

THE OFFICE OF COMMUNITY ORIENTED POLICING SERVICES (the COPS Office) was created in 1994 and has the unique mission of directly serving the needs of state and local law enforcement. The COPS Office has been the driving force in advancing the concept of community policing and is responsible for one of the greatest infusions of resources into state, local, and tribal law enforcement in our nation’s history.

Since 1994, the COPS Office has invested more than $11.4 billion to add community policing officers to the nation’s streets, enhance crime fighting technology, support crime prevention initiatives, and provide training and technical assistance to help advance community policing.

COPS Office funding has furthered the advancement of community policing through community policing innovation conferences, the development of best practices, pilot community policing programs, and applied research and evaluation initiatives. The COPS Office has also positioned itself to respond directly to emerging law enforcement needs.

Examples include working in partnership with departments to enhance police integrity, promoting safe schools, combating the methamphetamine drug problem, and supporting homeland security efforts.

Through its grant programs, the COPS Office assists and encourages local, state, and tribal law enforcement agencies in enhancing their homeland security efforts using proven community policing strategies.

Traditional COPS Office programs such as the Universal Hiring Program (UHP) give priority consideration to those applicants that demonstrate a use of funds related to terrorism preparedness or response through community policing. The COPS in Schools (CIS) program has a mandatory training component that includes topics on terrorism prevention, emergency response, and the critical role schools can play in community response.

Finally, the COPS Office has implemented grant programs intended to develop interoperable voice and data communications networks among emergency response agencies that will assist in addressing local homeland security demands.

The COPS Office has made substantial investments in law enforcement training. The COPS Office created a national network of Regional Community Policing Institutes (RCPI) that are available to state and local law enforcement, elected officials, and community leaders for training opportunities on a wide range of community policing topics. Recently, the RCPIs have focused their efforts on developing and delivering homeland security training. In addition, the COPS Office has made a major investment in applied research, which makes possible the growing body of substantive knowledge covering all aspects of community policing.

These substantial investments have produced a significant community policing infrastructure across the country as evidenced by the fact that at the present time, approximately 86 percent of the nation’s population is served by law enforcement agencies practicing community policing. The COPS Office continues to respond proactively by providing critical resources, training, and technical assistance to help state, local, and tribal law enforcement implement innovative and effective community policing strategies.

About PERF

THE POLICE EXECUTIVE RESEARCH FORUM (PERF) IS A NATIONAL organization of progressive law enforcement chief executives from city, county and state agencies who collectively serve more than half of the country’s population.

Established in 1976 by 10 prominent police chiefs, PERF has evolved into one of the leading police think tanks.With membership from many of the larger police departments in the country and around the globe, PERF has pioneered studies in such fields as community and problem-oriented policing, racially biased policing, multijurisdictional investigations, domestic violence, law enforcement response to people with mental illnesses, homeland security, management concerns, use of force, and crime-reduction approaches.

PERF’s success is built on the active involvement of its members: police chiefs, superintendents, sheriffs, and other law enforcement leaders.

The organization also has various types of membership that allow the organization to benefit from the diverse views of criminal justice researchers, law enforcement of all ranks, and others committed to advancing policing services to all communities. As a nonprofit organization, PERF is committed to the application of research in policing and to promoting innovation that will enhance the quality of life in our communities.

PERF’s objective is to improve the delivery of police services and the effectiveness of crime control through the exercise of strong national leadership, the public debate of criminal justice issues, the development of a body of research about policing, and the provision of vital management services to all police agencies.

In addition to its cutting-edge research and management and technical assistance programs, PERF continues to work toward increased professionalism and excellence in the field through its training, leadership, and publications programs. For example, PERF sponsors the Senior Management Institute for Police (SMIP), conducts searches for communities seeking police chief executives, and publishes some of the leading literature in the law enforcement field that addresses the difficult issues that challenge today’s police leaders.

PERF publications are used for training and promotion exams and to inform police professionals about innovative approaches to community problems. The hallmark of the publications program is translating the latest research and thinking about a topic into police practices that can be tailored to the unique needs of a jurisdiction.
