Emergent volunteerism in missing person cases — A Dutch case study.

In missing person cases, police often face spontaneous searches by citizens. This study examined the involvement of police and citizens in a well-known Dutch case. It shows that the relationship between police and volunteers is not static, but changes over time. Initially, citizens are more quickly organized and take charge. As the investigation progresses, different types of volunteers are incorporated into the police structure. Citizens pose dilemmas regarding direction and information sharing, but provide valuable search capacity and expertise. The results show the importance of not opposing citizen initiatives, but rather making contact, establishing structure and coordinating efforts early on. [ABSTRACT FROM AUTHOR]
