A government official told the Associated Press on Wednesday night that the massive paper trail in the Bernard Madoff fraud case has led investigators to a New York City warehouse containing boxes and file cabinets stuffed with documents that could reveal more clues about what may be the largest Ponzi scheme ever.

The official says the Queens building was used to store old records from Madoff’s investment firm, located across the East River in Manhattan. The official isn’t authorized to discuss the case publicly and spoke Wednesday on condition of anonymity.
