Here is the scam message. It is obviously fake.

This message is intended for “YOUR NAME HERE”. My name is Catherine Bus and I am calling you from the “Federal Investigation Department” and this call is to inform you there is a legal that has been filed against your name, your social and physical address is under federal investigation. So I want you to give me a call back and my department call back number is (301)202-9039.
I repeat (301)202-9039
Now, if we do not receive any call back from your end, unfortunately we need to transfer this case to the ??? in a legal way.
So, before we do it make sure you give us a call back.
