Groff's research focused on which phenomenon?

• A. Near repeat burglary
• B. Drug trafficking routes
• C. Cybercrime
• D. Domestic violence

Answer: (A)

The concept being tested is near-repeat victimization in burglary. Groff’s work investigates how burglary incidents tend to cluster in space and time: once a burglary happens, nearby addresses are more likely to experience another burglary in the short term. This pattern emerges because offenders may exploit familiar routes, routines, or vulnerabilities in nearby properties, leading to a temporary spike in risk around the initial incident. Understanding this helps explain why policing and prevention efforts can be concentrated in the areas surrounding a burglary to disrupt the short-term cluster. The other topics—drug trafficking routes, cybercrime, and domestic violence—do not describe this spatial-temporal clustering pattern in burglary that Groff examined.
