Back to being detective, I decided to cover more avenues in my plight to track down this package. Here's where I'm at:
I called customs at JFK Airport and they referred me to the Postal Office WITHIN JFK. The folks there said that every package shipped to the United States MUST have an identification number that starts with a "C". No package, they said, enters the good ole US of A without that ID number.
This is true, they said, even if the package was sent via standard airmail. The identification number is on the package and on the receipt received when the package was sent. They said without an ID number, they cannot help. BUUUT to be fair...I doubt that all airmail has this ID number (that's just my belief).
So now I'm trying to find this ID number. The search continues.....It's all kind of interesting actually!
