This paper examines three robbery incident summaries through the lens of tactical crime analysis, one of the primary methods used in modern law enforcement alongside strategic and administrative analysis. The paper identifies the incidents as a crime series based on consistent elements of modus operandi — including suspect clothing, verbal statements, cigarette theft, and vehicle use — while noting key differences across incidents. It discusses how clues such as temporary license plates, clothing descriptions, and movement patterns can assist in suspect identification, and proposes geographic profiling and offender profiling as work products to support apprehension efforts. The analysis illustrates how tactical crime analysis links individual events into actionable intelligence.
Crime analysis is one of the most important processes in the fight against crime and in efforts to enhance the effectiveness of the criminal justice system. In recent years, crime analysis has continued to expand within law enforcement agencies across the globe. This expansion has contributed to the development and use of different analytical methods, including strategic, tactical, and administrative crime analysis. Each of these techniques is applied when examining different types of crime incidents in order to understand and resolve them. This paper reviews a set of crime incidents using these analytical techniques and examines the various factors present in those incidents.
When reviewing the incident summaries, the most appropriate type of analysis is tactical crime analysis, whose main focus is to promote the short-term development of patrol strategies, investigative priorities, and resource deployment. The application of tactical analysis to these summaries is evident in the goal of determining the series and patterns of these crimes by linking them together (Stenton, 2006). Additionally, tactical analysis in this context focuses on identifying probable suspects responsible for the crime series and patterns, and on forecasting future incidents based on identified trends.
These incidents can be considered a crime series, which is defined as a crime pattern in which there is reasonable belief that the offenses are being committed by the same offender or group of offenders (McCoy, n.d.). Based on the incident summaries, there is sufficient evidence for that reasonable belief: the robberies share consistent characteristics in the appearance of the criminals, their verbal statements, their indistinguishable accent, their preference for Marlboro cigarettes, and the manner in which they leave the crime scene. In essence, these incidents constitute a crime series because of the consistent elements of modus operandi present in each of the three events.
The identity of the suspects involved in these crimes can be pursued through several clues evident in the incident summaries. One is the criminals' clothing — specifically, the use of a black hooded sweatshirt and unidentified footwear. A second clue is the temporary license plates on the Ford Taurus used to flee the crime scene. Temporary plates are a common investigative lead because they can be traced through dealer records and vehicle registration systems. A third clue is the suspects' movement onto Main Street after each incident, which helps narrow their potential destination or base of operations.
