Victim Vulnerabilities

This chapter examines the element of victim vulnerability as an important but often underrecognized factor in crime pattern identification. Vulnerabilities may be physical, psychological, social, environmental, or technological, and they influence how offenders select and exploit targets. By comparing these traits across cases, analysts and investigators can uncover offender decision-making processes and better understand crime dynamics. Examples range from age, disability, and social isolation to digital exposure and financial insecurity, each shaping the opportunity structures that offenders exploit. A case study of Delroy Grant, the “Night Stalker,” illustrates how the targeting of elderly victims obscured recognition of a serial pattern and delayed intervention. The discussion also highlights practical and ethical challenges, including inconsistent documentation, underreporting, and the risks of discriminatory profiling when vulnerabilities are used as analytical variables. Despite these limitations, integrating vulnerability data with modus operandi and forensic evidence strengthens both prevention strategies and investigative linkages. Ultimately, the chapter underscores the importance of treating victim vulnerabilities not as background context but as active elements in crime pattern formation and offender targeting.
