Concluding the interview
Discussion on concluding the interview:
Presume that you will need this witness again, so get their contact info, email, cell phone, etc. Explain where the case will go from here. Make sure they understand to contact you before they take any leave, move, go off to school, etc. Ask them to contact you if they speak to anyone else about the case, or if your conversation jogs any memory. If you have identified follow-up issues (for example, phone records) to collect, set a specific time and date for the meeting.
