Cumulative Strain Theory and Public Mass Murderers From 1990 to 2014 %A James Silver %A John Horgan %A Paul Gill %J Homicide Studies %@ 1552-6720 %D 2019 %R 10.1177/1088767918802881 %X Scholars have urged a shift in research on mass murder from the creation of typologies to theoretically rich, data-driven comparative examinations of the phenomenon. We seek to redress such calls in two ways. First, we analyze a unique sample of public mass murderers through the multistage explanatory model of cumulative strain theory. Second, we use a comparison group of similarly violent offenders¡ªlone actor terrorists¡ªto provide context to our findings. The results demonstrate that cumulative strain theory usefully describes the trajectory toward violence of public mass murderers, more so when a concept implicit in the theory¡ªgrievance¡ªis made explicit %K mass murder %K subtypes %K school shootings %K comparative %K methodology %K terrorism %K strain theory %U https://journals.sagepub.com/doi/full/10.1177/1088767918802881
