 You can report someone missing to any law enforcement officer. You don't have to try to contact missing persons. You don't have to do it in person necessarily. You can do it by phone as well. But you do need to speak with an actual police officer, and you're also going to need that missing person's name and date of birth. The benefits to reporting somebody where they were last seen as missing are that then the local law enforcement there have the easiest access to whatever evidence exists that might help track them down. And in cases where there was a criminal event that caused this person to go missing, then that's crucial. By the same token, one of the benefits to reporting somebody missing where they live is that then law enforcement are able to have a better chance of encountering them when they come home. Maybe we lose contact with the reporting party. So we need to go out and we need to look around the scene. We need to see what we can find, what clues we can find. That's a lot easier to do when we are the jurisdiction that took the report.
