- 1). Meet with the investigator that originally worked on the case. This officer will have the most information about the evidence and investigation that was originally completed. Ask the officer to re-evaluate the case.
- 2). Present the case data and files to a cold case unit that works with the department in the appropriate jurisdiction, if available. If the original investigator is cooperative, he can turn over the information to such a unit. If the original investigator feels opening the cold case is unwarranted, you may need to personally meet with the cold case unit or a supervisor and ask for a new examination of evidence.
- 3). Provide valid and concrete reasons why the cold case deserves a closer look. Police departments will only reopen cold cases if investigators can determine the availability of witnesses, motives and suspects. In addition, new evidence or new technology that can better interpret evidence provides justification for reopening a cold case, so keep up with technological advances and present that to the team.
- 4). Encourage the cold case unit or investigator to share the details of your case with other officers at specialized trainings. This will bring the expertise of various officers and agencies to your situation and may expose potential information that can lead to the case being reopened.
