A Colorado man charged with sexually abusing boys at a school he founded in Haiti has pleaded not guilty to more allegations.
Douglas Perlitz appeared Tuesday in federal court in New Haven.
The 39-year-old Perlitz, of Eagle, Colo., was charged last year with sexually abusing nine boys. Prosecutors doubled the number of alleged victims to 18 with a new indictment announced last week.
Perlitz pleaded not guilty last year to the original charges.
Perlitz, who previously lived in the Connecticut cities of Bridgeport, Stamford and Fairfield, is accused of threatening children with expulsion or withholding benefits if they didn't comply with his demands at the Cap-Haitien school.
