PROVIDENCE, R.I. (WPRI) — Central Falls municipal judge Joseph Molina Flynn abruptly resigned Thursday shortly after FBI agents raided his law offices in downtown Providence.

Central Falls Mayor Maria Rivera confirmed the resignation, calling the raid "deeply concerning." Rivera appointed Molina Flynn when she became mayor in 2021. Molina Flynn oversaw the city's traffic calendar.

"As the Central Falls community knows, transparency and accountability are priorities of mine," Rivera said. "In an effort to uphold the integrity and focus of the municipal court, Judge Molina Flynn has officially resigned his position."

Molina Flynn did not immediately respond to a request for comment Thursday.

An FBI spokesperson confirmed federal agents had served a court-authorized search warrant on an office building on Dorrance Street in Providence, but she declined to comment on what they were seeking.

A line of black SUVs and other vehicles were lined up outside of Molina Flynn's offices, which is a short distance from Providence Municipal Court.

The investigation into Molina Flynn started before President Donald Trump took office and is unrelated to his immigration-related executive orders, according to two people with direct knowledge about the investigation who would only speak on the condition of anonymity.

They said federal agents are looking at Molina Flynn over allegations that he defrauded people seeking representation on immigration-related matters. He had not been charged as of Thursday afternoon.

"The Office of Disciplinary Counsel is aware of the raid and that the attorney has not been charged criminally at this point," R.I. Courts spokesperson Lexi Kriss said in a statement.

According to his website, Molina Flynn has offices in Boston and Providence, and he handles immigration, family and criminal matters. He moved to the United States from Colombia when he was nine years old, according to a biography on his website, and he obtained lawful permanent status 15 years later before becoming a U.S. citizen.

Molina Flynn graduated from Johnson and Wales University in Providence. He then obtained his law degree from the University of Michigan Law School in Ann Arbor, according to his website. His biography also noted he was an adjunct professor at Roger Williams University Law School where he taught “Crimmigration.”

A RWU spokesperson confirmed he was previously employed at the university and taught one course last fall.

In Central Falls, Associate Judge Robert McConnell will serve in Molina Flynn's place until Rivera fills the vacancy, she said.
