A federal judge in Maine sentenced a man to more than six years in prison for conducting Internet scams on eBay. U.S. District Judge George Singal rejected on Monday a plea bargain from Charles Stergios, 21, because of the man’s failure to attempt to make restitution with his victims, according to Assistant U.S. Attorney Halsey Frank, who represented the state of Maine in the case. Stergios, who has been in jail on related charges since May 2004, admitted in earlier court proceedings that he had defrauded 50 individuals of at least $200,000 in cash and purchased goods through schemes executed over online auction site eBay.
