Man claiming to be Special Agent Ronald White from DEA looking for a Stanley Swenson in regards to a criminal investigation.  If you call back you get a voice recording saying you've reached the DEA Headquarters.  I did not leave a message and they immediately returned my call.  I said they have the wrong number and they hung up on me.  

Man claiming to be officer Ron White from the DEA regarding an open drug investigation looking for ME (sally xxxx).   Phone number was the 209-475-7091.  I am very glad to have found this link and info regarding it being a scam.  Company look-up via reverse phone number is the YMax Communications co although it was answered as DEA headquarters.
