I own a two bedroom rental property. Unbeknownst to me, the previous tenant allowed 5 of his "friends" (all with foreign sounding names) to utilize this address as their primary residence for mail. I was not aware of this until the tenant moved out and the new tenant moved in.
After almost two years, mail continues to flood the mailbox of the new tenant. I have been to the PO multiple times and they are not at all helpful since there is no forwarding address for these individuals (who are unknown to me). All mail is returned to the PO with "not at this address" on the envelope.
All mail is first class and financial in nature (bank statements, bills, credit card statements, etc). so I think something unsavory is going on but don't know for sure.
How can I get this mail to stop? What legal rights do I have?
