Because thieves typically set in motion a chain of events which does not end at the precise moment that a theft has been completed, the California legislature has placed a series of obstacles in the path of criminals to limit and control the movement, disposal, and use of stolen items. The law defines a person as a thief who (1) fails to make reasonable efforts to return lost property, (2) buys or receives property known to be stolen, or (3) conceals or withholds such property. Knowledge that property was stolen may be imputed if (1) the suspect had been put on notice, (2) the suspect should have had reason to be suspicious, and (3) the subject, even though suspicious, failed to investigate or find out if the item was stolen. Legal presumption of knowledge is shown if the suspect buys or receives items under circumstances which should cause suspicion and reasonable inquiry.
