Package that I did not mail, sent back to me "Return to Sender".

Ok, I don't understand what is going on here. About a month ago I received a letter from the USPS stating that a package I mailed did not have enough postage on it and that if the addressee did not agree to pay the needed postage, the package would be returned to sender. I looked at the address that was mentioned and looked back and saw where I had never mailed anything to said address. 

Today, I got a package dropped off by USPS marked that it had been returned to sender (me, apparently) and opened for inspection. My address was indeed the address in the corner for the return address printed on the shipping label but again, I did not recognize the address this item was suppose to goto and had never mailed anything to them. I opened the package and found that it contained children's toys and action figures. I have never seen these things in my life, much-less mailed them to anyone. What is going on here?

I can only guess that someone sold these items and used my address as their own? Why would someone do this? Is it some sort of scam? I don't know if this was an item purchased and sold on eBay or not, but figured sellers on here know a bit about shipping and was hoping to hear what y'all thought.

A few years ago I had that happen. Someone opened a USPS shipping account in my name. They were sending fake money orders with it as part of the "secret shopper scam". 

Some came back due to bad addresses. I reported it to the US postal service. They were very lackluster about it. Like why bother us?  I pressed for a case number and did get one.  I wanted to be covered but, that was the end of it.
