Operators of Transnational Elder Fraud Scheme Plead Guilty

Defendants caused over $5 million in losses to over 400 seniors across the United States

BOSTON - Four Dominican nationals have pleaded guilty, and another has been sentenced, for their roles in connection with a transnational "call center" operation in the Dominican Republic that tricked hundreds of elderly victims in the United States into believing that their grandchildren or other close family members were in trouble and needed money. In total, the investigation identified over 400 victims with an average age of 84, including at least 50 in Massachusetts, and more than $5 million in losses.

Oscar Manuel Castanos Garcia, 34; Joel Jose Cruz Rodriguez, a/k/a "Paflow," 34; Edward Jose Puello Garcia, 45; and Joel Francisco Mathilda Leon, 27, have each pleaded guilty to one count of conspiracy to commit mail fraud and wire fraud and one count of money laundering conspiracy. The defendants were indicted by a federal grand jury in May 2024. They were arrested in August 2025 in the Dominican Republic at the request of the United States, extradited, and detained pending trial.

A fifth defendant, Luis German Santos Burgos, 33, was sentenced on June 25, 2026 by U.S. District Judge Leo T. Sorokin to 48 months in prison and three years of supervised release for his role in the elder fraud operation.

A sixth defendant, Gerardo Heriberto Nuñez Nuñez, 41, has agreed to plead guilty to one count of money laundering conspiracy for his role in laundering scam proceeds from the United States to the Dominican Republic.

According to the charging documents, the defendants, led by Castanos Garcia, ran a sophisticated "call center" operation in the Dominican Republic that tricked hundreds of elderly victims in the United States into believing that their grandchildren and other close family members were in trouble and needed money. Once the defendants obtained the money, they laundered their illicit proceeds back to the Dominican Republic.

Castanos Garcia oversaw call centers in the Dominican Republic, where he employed co-conspirators who spoke English and carried out what are commonly known as "grandparent scams." These scams would begin with an "Opener" employee, who would call victims and pretend to be a grandchild who was in an accident. Then, a "Closer" would allegedly follow up with another call, pretending to be the grandchild's attorney, asking for a sum of money to pay for the grandchild's attorney's fees. Castanos Garcia ran these call center locations with the help of several managers, including Cruz Rodriguez and Puello Garcia, who supervised, instructed and paid the employees.

Callers for Castanos Garcia's call centers would instruct elderly victims to provide cash to "runners" in the United States, including Joel Francisco Mathilda Leon. Most often, the callers would instruct victims to give the packages with cash to rideshare drivers who were ordered to the victim's house by a runner. Runners would then have the unsuspecting rideshare drivers deliver the packages to the runners at nearby locations. In some cases, the callers would direct the victims to ship packages of cash to specified addresses via mail or commercial carriers.

Often times, the call center would call victims again and ask for additional funds for their grandchildren, sometimes two or three additional times. For example, callers would claim that there had been a "mix up" or that a "pregnant women's baby was lost in the crash."

At times, co-conspirators would order unwitting rideshare drivers to drive the elderly victims to the bank to withdraw additional funds.

Castanos Garcia directed the runners to deposit the victims' money into bank accounts or deliver it to co-conspirators. The operators of the scheme relied on money launderers in the United States and the Dominican Republic, including Nuñez Nuñez, to transmit proceeds from victims in the United States to Castanos Garcia and others in the Dominican Republic. As alleged in the indictment, Nuñez Nuñez provided call center operators with access to bank accounts in the names of purported businesses, into which runners deposited scam proceeds. He also arranged for the runners to hand-deliver cash from victims to individuals in New York and elsewhere. Nuñez Nuñez then provided cash to the call center operators in the Dominican Republic.

Santos Burgos ran another grandparent scam call center in the Dominican Republic and coordinated with Castanos Garcia to send U.S.-based runners to pick up scam proceeds for their respective operations.

Members of the public who believe they may be victims of this case, or other elder fraud scams, should contact [email protected] or call 1-800-CALL-FBI (1-800-225-5324). Suspected fraud can also be reported on the FBI's IC3 Elder Fraud Complaint Center.

The charge of conspiracy to commit mail fraud and wire fraud provides for a sentence of up to 20 years in prison, three years of supervised release and a fine of up to $250,000, or twice the loss to the victim. The charge of money laundering conspiracy provides for up to 20 years in prison, three years of supervised release and a fine of up to $500,000 or twice the amount of laundered funds, whichever is greater. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.

United States Attorney Leah B. Foley and Ted E. Docks, Special Agent in Charge of the Federal Bureau of Investigation, Boston Division made the announcement today. Assistant U.S. Attorney David M. Holcomb of the Criminal Division is prosecuting the case.

The details contained in the charging documents are allegations. The remaining defendants are presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.
