Street corner decisions: an empirical investigation of extortionist choices in El Salvador

ABSTRACT This paper identifies offender choice patterns associated with extortion subtypes in El Salvador, Central America. Previous research attributes the rise of extortion in the country to the evolution and propagation of Los Angeles-born street gangs Mara Salvatrucha (MS-13) and Barrio 18. Data from a unique business victimisation survey is used to analyse 53 decisions in 869 reported cases. The study borrows a multidimensional scaling method used in criminal profiling research to identify offender choice patterns. Cases are classified into extortion subtypes based on identified choice groupings. Key offender choices and location features are compared across extortion subtypes. Offender choice patterns identified in the study are consistent with systemic and opportunistic extortion described in previous literature. About a third of the cases are designated as hybrid extortions due to the blend of choice structuring properties they exhibit, which combines aspects of both systemic and opportunistic extortion.
