Tactical Crime Analysis: Identifying a Robbery Series
This paper examines the application of tactical crime analysis to a series of three related robberies occurring within a short timeframe in the same geographic area. The paper identifies the incidents as a crime series based on consistent modus operandi elements—including distinctive Halloween masks, clothing, stolen goods, getaway vehicle, and timing—and distinguishes these patterns from minor variations across incidents. It further outlines specific investigative clues that could identify suspects, such as a distinctive tattoo, a Ford Taurus with temporary tags, and the name "Nemo." The paper concludes by describing the intelligence product that should be developed and disseminated to patrol officers, including an APB, database searches, and targeted late-night patrol recommendations.
- Introduction: Type of Analysis Applied: Classifies the review as tactical crime analysis
- Identifying the Crime Series: Links three robberies as a single crime series
- Suspect Clues and Investigative Leads: Distinctive tattoo, vehicle, and name as leads
- Modus Operandi Elements: Ten consistent patterns across all three incidents
- Variations Across the Incidents: Deviations suggesting an unplanned third robbery
- Intelligence Product Development and Recommendations: APB, database search, and patrol guidance

What makes this paper effective
- It clearly applies a specific analytical framework — tactical crime analysis — and justifies that classification with a direct citation, grounding the argument in established definitions from the outset.
- The numbered modus operandi list is well-organized, methodically cataloguing ten consistent elements across the three incidents, making the evidence for a crime series concrete and easy to evaluate.
- The paper moves logically from analysis to action, translating observed patterns into specific, operational recommendations for patrol officers — demonstrating applied, not merely theoretical, crime analysis.
Key academic technique demonstrated
The paper demonstrates evidence-based pattern analysis: it draws on cited definitions of a "crime series" and then tests the available incident data against those criteria. By systematically comparing similarities and noting deviations, the author shows how analytical reasoning in criminal justice connects descriptive observation to investigative inference and actionable intelligence output.
Structure breakdown
The paper opens by classifying the type of analysis being performed, then builds the case for a crime series by enumerating shared modus operandi elements. It acknowledges deviations in a separate section and uses them to generate a hypothesis about suspect behavior. The final section translates all findings into a practical intelligence product with clear dissemination targets and follow-up steps, creating a complete analytical workflow from observation to recommendation.
Introduction: Type of Analysis Applied
The type of analysis being performed when reviewing the incident summaries is tactical crime analysis, as the crimes were all committed within a few weeks of one another in the same region. The aim of the review is to provide "information to assist operational personnel in the identification of crime trends and in the arrest of criminal offenders" (University Police, 2018).
Identifying the Crime Series
As Bruce and Santos (2011) point out, a crime series is "a group of similar crimes thought to be committed by the same individual or group of individuals acting in concert" (p. 3). Because these three robberies bear striking similarities to one another, they may be considered a crime series. For example, the perpetrators were wearing the same masks in each case, took the same kind of cigarettes as well as cash, and in two of the three cases the same type of getaway vehicle was used — a Ford Taurus. In the first case the vehicle was not identified, but it was most likely the same one. This pattern of evidence strongly supports classifying these incidents as a single crime series.
