A man from Summit, N.J., pleaded not guilty this morning in New London Superior Court to charges that he marked cards with invisible ink while playing Mississippi Stud Poker at Mohegan Sun last month.

Bruce Koloshi, 54, who is also known as Jeffrey William Elliot, has been held in lieu of $300,000 at the Corrigan-Radgowski Correctional Institution since members of the state police Casino & Licensing Unit arrested him on on Sept. 15. Koloshi was taken into custody after a casino surveillance operator notified the troopers that Koloshi appeared to be cheating.

Koloshi, who has cheating convictions in Nevada, Iowa and Illinois, told them the detectives he was trying to raise bond money for an anticipated cheating arrest in Baton Rouge, La. State police said Koloshi admitted to marking cards with a type of ink that is visible only with special contact lenses so that he could gain an advantage by placing higher bets when he knew which card would be played. The troopers confiscated the contacts, which they said Koloshi was wearing along with eyeglasses.

Defense attorney Martin J. Minella, new to the case today, said he would be filing motions to contest the jurisdiction of the Superior Court to hold Koloshi on the cheating charges and the constitutionality of Koloshi’s pending extradition to Louisiana to face charges that he cheated at the L’Auberge Casino in Baton Rouge. Minnella said he would be trying to resolve the Louisiana charges without extraditing Koloshi to that state.

Koloshi’s next court date is Nov. 15. He is charged with cheating, conspiracy to commit larceny, criminal impersonation and being a fugitive from justice
