A former Dorchester resident who federal law enforcement official say stole hundreds of thousands of dollars in tax refund money using identity theft pled guilty to the scheme in a Boston courtroom this week.

Junior Alberto Lopez, 32, a Dominican national, admitted to conspiracy, device fraud, and aggravated identity theft in federal court. Lopez was extradited from the Dominican Republic earlier this year after he fled the US after making bail in 2015.

The US Attorney’s office says that Lopez and a group of co-conspirators “unlawfully obtained” the vital statistics of more than 700 people, mostly residents of Puerto Rico between May 2011 and February 2013. They used the fake identities to then create and file false tax returns for three years— successfully getting tax refunds using prepaid debit cards, which were delivered to addresses in Boston and elsewhere. Lopez and his co-conspirators then cashed and redistributed the checks and debit cards, according to the charges.

He faces up to 10 years in prison, a fine of $250,000 and will be subject to deportation. A sentencing hearing will be held on Sept. 18.
