Environmental Criminology Research Inc.
Environmental Criminology Research Inc. (ECRI) is a crime analysis software company based in Vancouver, British Columbia, Canada. The company develops tools for police, military and security use. ECRI pioneered the use of geographic profiling software for serial crime analysis. Rigel Software ECRI’s Rigel software was first introduced in 1997 and is based on the doctoral dissertation of Dr. Kim Rossmo, who co-founded ECRI. Rossmo’s criminal geographic targeting (CGT) model, which produces a “probability surface” that shows the relative likelihood of the offender’s base of operations, is patented. Users of the Rigel software include the national police agencies of Canada, the United States, and several European nations, as well as many smaller regional and local police forces. The software utilizes data such as crime locations, suspect information, case details and investigator details to analyze a series of linked crimes and determine the most probable locations of ...

Software Development
Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development involves writing and maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through to the final manifestation of the software, typically in a planned and structured process. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. Methodologies One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies are best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations.

Beltway Sniper Attacks
The D.C. sniper attacks (also known as the Beltway sniper attacks) were a series of coordinated shootings that occurred during three weeks in October 2002 throughout the Washington metropolitan area, consisting of the District of Columbia, Maryland, and Virginia. Ten people were killed, and three others were critically wounded. The snipers were John Allen Muhammad (age 41 at the time) and Lee Boyd Malvo (age 17 at the time), who traveled in a blue 1990 Chevrolet Caprice sedan. Their crime spree, which began in February 2002, included murders and robberies in several states, which resulted in seven deaths and seven injuries. In total, the snipers killed 17 people and wounded 10 others in a 10-month span. In September 2003, Muhammad was sentenced to death, and in October, Malvo, a juvenile, was sentenced to six consecutive life sentences without parole. In November 2009, Muhammad was executed by lethal injection. In 2017, the United States Court of Appeals for the Fourth Circ ...

Crime Mapping
Crime mapping is used by analysts in law enforcement agencies to map, visualize, and analyze crime incident patterns. It is a key component of crime analysis and the CompStat policing strategy. Mapping crime, using Geographic Information Systems (GIS), allows crime analysts to identify crime hot spots, along with other trends and patterns. Overview Using GIS, crime analysts can overlay other datasets such as census demographics, locations of pawn shops, schools, etc., to better understand the underlying causes of crime and help law enforcement administrators to devise strategies to deal with the problem. GIS is also useful for law enforcement operations, such as allocating police officers and dispatching to emergencies. Underlying theories that help explain spatial behavior of criminals include environmental criminology, which was devised in the 1980s by Patricia and Paul Brantingham, routine activity theory, developed by Lawrence Cohen and Marcus Felson and originally publish ...

Geographic Profiling
Geographic profiling is a criminal investigative methodology that analyzes the locations of a connected series of crimes to determine the most probable area of offender residence. By incorporating both qualitative and quantitative methods, it assists in understanding spatial behaviour of an offender and focusing the investigation to a smaller area of the community. Typically used in cases of serial murder or rape (but also arson, bombing, robbery, terrorism and other crimes), the technique helps police detectives prioritize information in large-scale major crime investigations that often involve hundreds or thousands of suspects and tips. In addition to determining the offender's most likely area of residence, an understanding of the spatial pattern of a crime series and the characteristics of the crime sites can tell investigators other useful information, such as whether the crime was opportunistic and the degree of offender familiarity with the crime location. This is based on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Offender Profiling
Offender profiling, also known as criminal profiling, is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator. Multiple crimes may be linked to a specific offender and the profile may be used to predict the identified offender's future actions. In the 1980s, most researchers believed offender profiling was relevant only to sex crimes, like serial rape or sexual homicide, but since the late 1990s research has been published to support its application to arson (1998), and then later terrorism (2000) and burglary (2017). Theory Psychological profiling is described as a method of suspect identification which seeks to identify a person's mental, emotional, and personality characteristics based on things done or left at the crime scene. There are two major assumptions made when it comes to offender profiling: behavioral consistency and homology. Beha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rossmo's Formula
Rossmo's formula is a geographic profiling formula to predict where a serial criminal lives. It relies upon the tendency of criminals to not commit crimes near places where they might be recognized, but also to not travel excessively long distances. The formula was developed and patented in 1996 by criminologist Kim Rossmo and integrated into a specialized crime analysis software product called Rigel. The Rigel product is developed by the software company Environmental Criminology Research Inc. (ECRI), which Rossmo co-founded. Formula Imagine a map with an overlaying grid of little squares named sectors. If this map is a raster image file on a computer, these sectors are pixels. A sector S_ is the square on row ''i'' and column ''j'', located at coordinates (X_,Y_). The following function gives the probability p_ of the position of the serial criminal residing within a specific sector (or point) (X_,Y_): p_=k \sum_^ \left \underbrace_ + \underbrace_ \right where: \phi_= ...

Criminology
Criminology (from Latin , "accusation", and Ancient Greek , ''-logia'', from λόγος ''logos'' meaning: "word, reason") is the study of crime and deviant behaviour. Criminology is an interdisciplinary field in both the behavioural and social sciences, which draws primarily upon the research of sociologists, political scientists, economists, psychologists, philosophers, psychiatrists, social workers, biologists, social anthropologists, as well as scholars of law. Criminologists are the people working and researching the study of crime and society's response to crime. Some criminologists examine behavioral patterns of possible criminals. Generally, criminologists conduct research and investigations, developing theories and analyzing empirical patterns. The interests of criminologists include the study of nature of crime and criminals, origins of criminal law, etiology of crime, social reaction to crime, and the functioning of law enforcement agencies and the penal insti ...
