I got a call from a co-worker saying that a Mr Larson was on the phone, but he asked for me by my old married name.Haven't been that name in 33 years.  When she tried to transfer the call, he hung up.  Then proceeded to leave another message on the same girls phone, it was a debt collection pre-recorded call, saying if you are me please listen if not please hang up. Luckily she recorded the call and the phone# and gave me the information.  I called back that same night after I got home from work and the place was closed.  It is reporting as a collection agency in Minnesota.  The same night I got a call from yet another girlfriend saying she got a call from the same person telling her that I better call him or else. That he had sent me papers, never got any papers, a case file number and basically told her ABOUT ME..  I got home tonight and had yet another call same thing, same guy.  No info on what he was calling about just a case file number.  Yet he told my friend more information than he would tell me.  Sounds like the same problem I had last year when my info was leaked out.  Sounds like he is doing some digging on facebook in order to find my friends.  So be careful.
