I just got a letter at my address directed to someone else.

I do not recognize the name as a neighbor or previous owner of this house (I've been here for 7 years).

Its from TurboTax with a plastic card inside, making me presume it's somebody's tax rebate. But the address and name make me suspicious that it may be a fraud.

So. Do I just give it back to the mailman? or should I go to the post office with my suspicions? Or to the police?

My wife suggest destroying it, but I think that would be illegal.

Suggestions?
