Prosecutors Had a Drugs-for-Votes Scheme “Locked Up.” Under Trump, They Were Told Not to Pursue Charges.

To the narcotics agents investigating drug smuggling in Puerto Rico prisons, it seemed at first like a typical scheme: associates of an inmate gang sneaking drugs into the prison, gang members distributing them inside and bank records showing the money flowing.

Then the agents discovered something unusual.

Leaders of the prison gang known as Los Tiburones, or the Sharks, were selling drugs to inmates not only for money, but for their votes. Specifically, votes for now-Gov. Jenniffer González-Colón, a longtime Republican and supporter of President Donald Trump, investigators found.

To make sure the inmates — many of whom were addicted — complied, the gang’s leaders threatened violence and to withhold drugs, the investigators learned. Corrections employees in on the plan looked the other way as the gang, formally known as Group 31, ran the enterprise.

What at first seemed like a routine drug case had turned into something bigger. Puerto Rico, along with just a couple of U.S. states, allows inmates to vote. Puerto Ricans living in the territory can vote in all contests except federal general elections. It is a felony to willfully offer money or gifts in exchange for support at the polls. A conviction carries fines of as much as $250,000 and imprisonment of up to two years.

Investigators had gathered solid evidence of election fraud implicating both inmates and staff, and they were working toward determining whether González-Colón or her campaign was involved, four people with knowledge of the case told ProPublica. They requested anonymity because they are not authorized to speak publicly about the case.

But as federal prosecutors prepared an indictment against the inmates and staff in November 2024 — just days after Trump won the election and González-Colón clinched the governorship — they received a surprising directive. Their bosses in the U.S. Attorney’s Office for the District of Puerto Rico instructed them to exclude the voting-related counts against the inmates and all charges against the prison staff, an investigation by ProPublica found.

In December, they filed an indictment charging 34 inmates and associates with crimes including drug distribution resulting in at least four overdose deaths, money laundering and possessing a firearm. And while prosecutors described the drugs-for-votes scheme in the court filing, they did not include a single charge related to it.

Soon after Trump took office, the lead prosecutor, Jorge Matos, was told by a supervisor to take the investigation no further, according to four people familiar with the case.

“Before the election, it was definitely full steam ahead,” said one person familiar with the case. “After the election, that all changed.”

For those working on the case, the decision to scrap the investigation was especially puzzling given the new president’s agenda; Trump issued executive orders in early 2025 aimed at eradicating drug traffickers and declaring election integrity “fundamental” to maintaining American democracy.

People close to the case wondered if politics had played a bigger role than law and order. Trump congratulated González-Colón in a letter shared at her January 2025 inauguration saying, “I am so proud of your resounding victory.” That same month, she pushed to erect a statue of him at the Capitol building in San Juan alongside other presidents who’ve visited the island. “He deserves that,” she said, according to an official post from the Federal Affairs Administration of Puerto Rico on X.
