Several people have been charged in Rhode Island in two separate tax refund schemes that federal prosecutors say could have netted them $1.6 million. The office of US Attorney Peter Neronha said four people have pleaded guilty and one has agreed to plead guilty in a scheme to use stolen identity information from hundreds of people from Puerto Rico. Prosecutors said they would file fake W-2 forms along with the stolen information, then receive checks ranging from approximately $3,000 to $10,000 to addresses in Providence. They received nearly $600,000 in the scheme. Separately, prosecutors said two other people used stolen information from 1,300 people to receive tax refunds in a scheme designed to receive more than $1 million. Both of those people have pleaded not guilty.
