STAMFORD \u2014 State prosecutors will proceed with its case against a Stamford man accused of orchestrating a \u201clong-running\u201d dog-running scheme after they decided to waive a warrant that would have seen him extradited. Deputy Assistant Margaret Moscati said during a hearing on Monday that the state had decided not to extradite Nygel Joseph, 23, to New Jersey, where he faces unrelated charges. Joseph will remain in Connecticut to face racketeering, first-degree larceny, conspiracy to commit first-degree larceny, nine counts of conspiracy to illegally use a payment card, illegal trafficking in personal identifying info, animal cruelty and importing a dog without a health certificate charges, state prosecutors announced on Monday. Joseph is one of four people \u2014 Devon Sherman, 25; Ebony Ayala, 23; and Paul Joseph, 23 \u2014 accused of using stolen identities to purchase puppies from around the country and sell them out of a Glenbrook home. As a part of an investigation into the dog-running operation, Stamford Animal Control seized 22 dogs from the accused. Investigators were first alerted to the alleged dog-running scheme on Feb. 19 when an employee at Cornell University Veterinary Specialists in Stamford reported that a group of individuals had been bringing multiple dogs in and were using stolen credit cards to pay for the nearly $25,000 that they racked up in medical bills, investigators Michael Stempien and Vanessa Lynn wrote in Sherman\u2019s arrest warrant affidavit. The warrant states the suspects brought nine puppies to the vet in varying states of malnutrition and illness between October 2020 and March 2021. In one trip, vets needed to remove the right eye from a 7-month-old shiba inu because of trauma, according to warrant. In another trip, they brought an 8-week-old French bulldog needed to be euthanized because it \u201carrived comatose and severely emaciated,\u201d the warrant said. During the ensuing investigation, police discovered a dead \u201cyoung looking, black female toy poodle\u201d in the garbage of the suspects\u2019 Glenbrook home, according to the warrant. A later diagnostic exam revealed the dog had died of bronchopneumonia, the warrant said. Based on this evidence, police executed a search warrant on the Belltown Road home in March. It was during this raid that police first arrested Nygel Joseph on a lone second-degree forgery charge, as well as a citation for operating a pet store without a license. His alleged accomplices \u2014 Sherman, Ayala and Paul Joseph \u2014 were arrested in April on racketeering charges and more. Earlier this month, Nygel Joseph was arrested on new charges as police discovered new information on the alleged operation. On Monday, Nygel Joseph entered not guilty pleas to all charges. His next court date is scheduled for July 6.
