Cold Case Safety Net: Missing & Unidentified Persons

View the course syllabus

This course is designed for all agencies, regardless of size, which handle long-term missing and unidentified person cases. This course will provide an efficient and effective four-step process to initially address all missing and unidentified cold cases uniformly, and ensure that investigators receive maximum benefits of database searching and outside resources with minimal initial effort. Once an initial cold case safety net response is complete, traditional cold case selection factors can be applied to prioritize cases for further investigative response.

Upon completing this course, participants will understand:

  • How public records databases can help locate voluntary missing persons and validate missing person reports
  • Why missing persons must be entered into NCIC and NamUs
  • The benefits of having family members of missing persons use NamUs
  • "Best practices" that will maximize DNA comparisons and searching in the Combined DNA Index System (CODIS)
  • How errors or incomplete data in missing/unidentified cases can impede associations and how the application of the Cold Case Safety Net can overcome those issues
