Introduction

The social nature of crime is one of the most well-recognized and established features of offending. Accomplices come in many forms, ranging from informal co-offenders drawn from available pools of offenders (i.e., friends, acquaintances) to more formal gang-related associates. For the purposes of this review, an accomplice will be considered anyone an individual has engaged in crime or participated in a criminal enterprise with. This broad definition (as opposed to its strict legal definition) enables an exhaustive and theoretically meaningful assessment of the group nature of crime to include collective spontaneous crime, co-offending, gang-related, and organized crime. Even within various accomplice relationships, individuals occupy various roles and positions that contribute to the diffusion of information within accomplice networks, commission of crime, and consequences. The study of accomplices has led to descriptive patterns of group-based offending, theoretical development aimed at understanding the decision to engage in crime with others, and a consideration of how such involvement impacts subsequent behavior. The following entry overviews key areas related to accomplices and references scholarship that explores this important dimension of crime.

General Overviews and Classical Texts

Given the breadth of whom can be considered an accomplice, there is a wide array of scholarship that provides strong overviews of types and implications of various accomplices. Breckenridge and Abbott 1912 (p. 35) acknowledges that “there is scarcely a type of delinquent boy who is not associated with others in his wrongdoing.” Shaw and McKay 1942 is among one of the first sources to identify the prevalence of engaging in group offending among juveniles in the Cook County Juvenile Court. The seminal depiction of gangs in Thrasher 1927 provides insight into the nature and development of gangs. Short and Strodtbeck 1965 offers one of the first theoretical considerations of the social processes that facilitate youth involvement in gang and group delinquency. Building on these earlier works, a number of sources have reinvigorated the study of accomplices. Nearly fifty years after Shaw and McKay 1942, Reiss 1986 and Reiss 1988 (cited under Policy Implications of Accomplices) reintroduced the study of co-offending by examining patterns of co-offending across criminal careers and highlighted the need for more rigorous research in this area. Klein and Maxson 2006 and Decker and Pyrooz 2015 similarly explore the state of knowledge on the study of gangs. In a much broader consideration of the role of accomplices and peers, Warr 2002 provides a strong review of the theoretical mechanisms and implications associated with the group nature of crime. Morselli 2009 presents several case studies demonstrating the applicability of social network analysis to studying criminal organizations and groups. Most recently, van Mastrigt and Carrington 2019 offers an extensive review of co-offending from a developmental and life-course perspective. It should be noted that the majority of research on accomplices is derived from American, Canadian, and UK samples and therefore should be contextualized when considering how these findings extend to other societies or cultures.
