The number of civilian crime investigators (CIs) has been increasing among the police, a trend that is called civilianisation. However, conflicts have arisen from perceptions that civilian CIs undermine professional police efforts. The purpose of this study was to investigate the intersection of doing gender and professional identity in narratives on inclusion and/or exclusion in CIs' professional practices. Because professional background and gender composition change with the civilianisation of the police, this study included interviews with 48 female CIs from Sweden. The study showed that aspects of belongingness and uniqueness interact in complex ways and conclude that the intersection of being a civilian CI and a woman is at the core, especially in narratives on exclusion. Taken together, this means that civilian CIs' narratives are important to learn from and can help the police become aware of obstacles to and opportunities for civilian employees' full participation in the criminal investigation practice. Aspects of belongingness and uniqueness are discussed to contribute knowledge of how gender and professional identity can be redone in a way that helps reduce future barriers to full inclusion of female and civilian CIs in police work.
