 Dudley was among more than five dozen defendants in the case. The majority pleaded guilty. Prosecutors said the 38-year-old worked at a boiler room call center in Fridley. Investigators traced 3,400 fraudulent calls to him, including several to undercover agents. Two others tried and convicted alongside Dudley, Armando Miller and Tashina Crump, are expected to be sentenced later this summer. I'm Matt Sepik, Minneapolis.
