A trail of money that began with triple-digit loans to troubled New Yorkers and wound through companies owned by a former used-car salesman in Tennessee led New York prosecutors on a yearlong hunt through the shadowy world of payday lending, the New York Times DealBook Blog reported today. That investigation culminated yesterday with state prosecutors in Manhattan bringing criminal charges against a dozen companies and their owner, Carey Vaughn Brown, accusing them of enabling payday loans that flouted the state’s limits on interest rates in loans to New Yorkers. In the indictment, prosecutors outline how Brown assembled “a payday syndicate” that controlled every facet of the loan process — from extending the loans to processing payments to collecting from borrowers behind on their bills. The authorities argue that Brown, along with Ronald Beaver, who was the chief operating officer for several companies within the syndicate, and Joanna Temple, who provided legal advice, “carefully crafted their corporate entities to obscure ownership and secure increasing profits.”
