Chris Walker with the Department of US Treasury about a legal matter and that if we did not call back there would be major legal repercussions. He called my parents home line where I have not lived in over 8 years.

My friend received a threatening call from 415-506-2404 regarding a warrant for her arrest in California. She lives in a completely different state.

'Chris Walker' called and left me a voice mail today too.  I am glad I found your post.
