I had to deal with this myself once (tracked down a stolen laptop). The local ordinance is called "receipt of stolen property" and is a crime, but it requires knowledge that that the property is stolen or a preponderance of evidence that the individual should have reasonably known that the property was stolen.
But being in possession of stolen property is enough to give an officer probable cause and you'll probably be charged with something.
