It’s worth your while to have details recorded while they’re fresh in your mind. Even information that doesn’t seem particularly relevant may prove useful (to you and/or police) later on. A completed form will help when reporting to police and appealing to the public.
Keep either a hard copy or soft copy of notes detailing facts, contacts etc. Digital records can help you to share the information efficiently, but you may want to use a notebook instead – do whatever is natural to you. Download, save and complete: Missing Person Details Form
Also consider the following:
- Create a timeline of events noting people involved, times – anything you can think of.
- Check any accounts that you may share (or know the login details for) for clues.
- Call their close friends and connections, write down anything relevant and ask them to call you back if they remember something important.
