John O’Brien, Wire Fraud, Rhode Island 2026

An Irish national who was living unlawfully in the United States was sentenced today in federal court in Rhode Island for his role in a scheme to defraud homeowners in Rhode Island and Massachusetts.

John O’Brien, 28, was sentenced by U.S. District Court Chief Judge John J. McConnell, Jr. to 56 months in federal prison. He is expected to be deported following the completion of his sentence.

O’Brien pleaded guilty on December 11, 2025, to wire fraud.

“John O’Brien’s scheme was not just fraudulent, it was predatory. He deliberately targeted homeowners and exploited their trust for personal and financial gain,” said United States Attorney Charles C. Calenda. “This case reflects a broader pattern of individuals known as ‘Traveling Conmen’ who cross state lines for the purpose of defrauding victims. Individuals who engage in this kind of calculated deception should expect to be aggressively investigated and prosecuted in federal court.

“O’Brien preyed on unsuspecting homeowners in Rhode Island and Massachusetts by posing as a skilled tradesman and contractor—someone they could trust. Instead, this conman fleeced homeowners of upwards of $1 million while inflicting substantial damage to their homes. In one case, O’Brien, an illegal immigrant from Ireland, used his origin to build rapport with an elderly veteran in Warwick, Rhode Island over their shared Irish heritage only to extort him for tens of thousands of dollars in unnecessary home repairs,” said Homeland Security Investigations New England Acting Special Agent in Charge Jeffrey Grimming.

Colonel Michael Lima of the Warwick Police Department stated, “This case is a direct result of the exceptional work of our detectives and the strong partnerships we’ve built with our local, state, and federal law enforcement colleagues. Their persistence, attention to detail, and commitment to protecting our community ensured that a sophisticated and predatory scheme was thoroughly investigated and brought to justice.
