This article asserts that the deviant case method offers a potential avenue for enhancing theory directed at explaining crime by using more available information to better connect the process of analyzing cases with that of explanatory refinement and elaboration. This approach has facilitated theoretical development in other social sciences and has proven useful where applied in criminological inquiry. Extant research is reviewed, and an empirical example is presented to demonstrate how this approach might be operationalized in criminological inquiry using quantitative methods. Conclusions relevant to future research are considered. (Published Abstract)
