They release Eric Trump’s address in this article!!

When your address is Trump Parc East, NY, NY it doesn't take much to get it there.

The risk ratio is low for the sender. A pro would kill the family cat and send a stranger to give a verbal warning or some such. If Trump or family gets the real thing, they'll know it. Fortunately, they have their own resources and don't have to rely on Obama's people.

There are many Trump bldgs. in NYC. Although I never thought about it, I wouldn’t immediately guess that he lived in a Trump building on Central Park South. For all I know, he could have lived in a mansion in CT.

The mailer obviously knew exactly where he lived.
