Samenvatting

This article examines the use of citizen participation in urgent missing person cases. The Theory of Planned Behavior was used to examine which specific considerations investigators have in this regard and which have the greatest influence on the choice of whether or not to involve citizens. The findings suggest that this choice is primarily attitude-driven. Detectives are predominantly positive about participation, but see harm to the investigation as the main risk. A practical implication is to focus collaboration primarily on professionally organized groups of citizens to reduce (perceived) risks.
