D Street Gang Associate Arrested for Selling Firearm and Fentanyl to Undercover Law Enforcement

BOSTON – An associate of the D Street Projects gang in the South Boston area has been arrested and charged for allegedly selling a firearm and fentanyl to an undercover law enforcement agent.
Junior Martinez-Perello, 25, was charged with one count of possession with intent to distribute, and distribution of, fentanyl. Martinez-Perello was arrested this morning and, following an initial appearance in federal court in Worcester, was ordered detained pending trial.
According to the charging documents, Martinez-Perello communicated with undercover law enforcement about selling 100 grams of fentanyl and a firearm. It is alleged that Martinez-Perello agreed to meet on May 30, 2025 in Boston for the drug and gun deal. On that date, Martinez-Perello allegedly informed the undercover agent that he would always have firearms available and not to be concerned about purchasing firearms from him, and that he would be able to obtain and distribute half-kilogram quantities of fentanyl in the near future.
It is further alleged that, during the controlled purchase, Martinez-Perello explained how the safety feature worked on the firearm. At one point, Martinez-Perello allegedly pointed the loaded firearm towards the ground, manipulated the firearm in a fashion that was consistent with rendering the firearm safe and attempting to remove the live ammunition from the firearm. During this process, Martinez-Perello disengaged the safety mechanism on the firearm and fired one round into the floor.
The charge of possession with intent to distribute, and distribution of, fentanyl provides for a sentence of up to 20 years in prison, at least three years and up to a lifetime of supervised release and a fine of up to $1 million. 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 Scott Riordan, Acting Special Agent in Charge of the Bureau of Alcohol, Tobacco, Firearms & Explosives, Boston Field Division made the announcement today. Assistant U.S. Attorney John T. Dawley of the Organized Crime & Gang Unit is prosecuting the case.
This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs) and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood.
The details contained in the charging documents are allegations. The defendant is presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.

What do you expect from a anti police mayor? Tom Homan is coming.
Make Southie Southie Again!!
Before everyone knew each other we talked to each other. Today you can’t even get a hello.
You barely see children playing even on Saturdays.
Where are the high school kids? They used to hang out all the time. Where did they all go? It’s sad to see this place turn into something you would have never thought it would.
Who knows what the next 25 years will bring? God willing, Southie and the rest of Boston will dump these liberal/socialist politicians and put some common sense people in there.
