Numbers matter: Characteristic differences between lone, duo and 3+ group rapes
How does rape change when offender number is increased? What are the differences when one individual rapes, as opposed to two, or more? Although rape in general is difficult to prosecute successfully (Martin & Powell, 1994), multiple perpetrator rape (MPR) poses a significant investigative challenge due to the number of offenders involved and their various behaviours and roles (Chambers, Horvath & Kelly, 2010; Porter & Alison, 2006; Sanday, 1990). This can lead to only a few offenders, and in some cases none at all, being identified and held responsible for their crime (Horvath, Tong & Williams, 2011; Stern, 2010).
