Even though it is possible to trace cell phone location accurately, it is not something that you and I have the ability to do for the most part. In order to get this information, you have to have a court order that will allow you to get private information and quite honestly, that is not available to the public. One thing you may be able to do is to talk to the police to see if they are able to triangulate the signal that is coming from the cell phone if it is a police emergency. Other than that, you don’t have many choices.
