Interesting question. If there was a truly a place to go to look for a missing person, then no one would really be missing would they? Locating someone who is missing really depends on how long ago they’ve gone away and whether they are missing from everyone or just hiding out from you. First, if you suspect foul play and the disappearance just occurred you should contact the police. Next, you may want to consider hiring your own Private Investigtor. Last, if the missing person is just someone you’ve lost touch with or someone who is avoiding you , it is amazing who or what you can find online.
