A Federal Felon Arrested for Possession of Firearms, Ammunition and Machinegun

SAN JUAN, Puerto Rico – A federal grand jury returned a two-count indictment charging Jeffrey Omar Delgado-López with possession of a machinegun and with being a felon in possession of firearms and ammunition, announced W. Stephen Muldrow, United States Attorney for the District of Puerto Rico. The Federal Bureau of Investigations (FBI) is in charge of the investigation under the direction of Special Agent in Charge Devin J. Kowalski.

According to the Government’s allegations, on June 1, 2025, Delgado-López possessed a Glock pistol model 19 loaded with 31 rounds of ammunition and an additional 42 rounds of 9mm ammunition, as a convicted felon.

The indictment also alleges that Delgado-López possessed a machinegun, specifically a Glock pistol model 19 modified to fire automatically more than one shot without manually reloading by a single function of the trigger.

“Fighting gun violence remains a top priority for our office and the Justice Department and, as this case shows, we are steadfast in our commitment to prosecute those who violate federal firearms laws,” said W. Stephen Muldrow, U.S. Attorney for the District of Puerto Rico.

“Jeffrey Omar Delgado-López was under federal supervised release, and he chose to break the law again--arming himself illegally in the streets of Mayagüez. This is unacceptable,” said Devin J. Kowalski, Special Agent in Charge of the FBI’s San Juan Field Office. “Crushing violent crimes also means preventing them. We will not allow armed felons to operate in our communities.”

Assistant U.S. Attorneys Carlos J. Romo-Aledo and Alberto R. Lopez Rocafort, Chief of the Gang Section, are in charge of the prosecution of the case. If convicted, the defendant faces a sentence of up to fifteen years in prison.

An indictment is merely an allegation and all defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
