The purpose of the study was to provide information about law enforcement agencies' handling of missing child cases, including the rates of closure for these cases, agencies' initial investigative procedures for handling such reports, and obstacles to investigation. Case types identified include runaway, parental abduction, stranger abduction, and missing for unknown reasons. Other key variables provide information about the existence and types of policies within law enforcement agencies regarding missing child reports, such as a waiting period and classification of cases. The data also contain information about the cooperation of and use of the National Center of Missing and Exploited Children (NCMEC) and the National Crime Information Center (NCIC).
