A metro Atlanta business entrepreneur and his lawyer were sentenced to a decade in prison for illegally siphoning millions of dollars from unwitting investors through two separate stock market schemes.

Judge Leigh Martin May of the U.S. District Court for the Northern District of Georgia sentenced attorney Marc Bercoon, 57, of Atlanta, and William Goldstein, 54, of Alpharetta, to 10-year sentences Tuesday after a two-day hearing. The federal jury in Atlanta convicted them of conspiracy, mail fraud, wire fraud and securities fraud in February for their role in what’s known as a “pump-and-dump” scheme.
