Elvin Martinez-Flores Pleads Guilty to Fentanyl Trafficking

BOSTON – A shocking case of fentanyl trafficking has come to a head, with an associate of the notorious 18th Street Gang taking a guilty plea in federal court. Elvin Martinez-Flores, 23, of Everett, Massachusetts, has been charged with distributing and possessing with intent to distribute 40 grams and more of fentanyl.

According to court documents, on Sept. 20, 2024, Martinez sold approximately 400 pressed fentanyl pills to a cooperating witness. This was not an isolated incident, as Martinez sold another 500 pressed fentanyl pills to the same witness on Oct. 28, 2024.

The charge of distribution of and possession with intent to distribute 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 $1,000,000. 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, Kim Milka, Acting Special Agent in Charge of the Federal Bureau of Investigation, Boston Division, and James M. Ferguson, Special Agent in Charge of the Bureau of Alcohol, Tobacco, Firearms and Explosives, Boston Field Division, made the announcement today.

A team of agencies provided valuable assistance in this case, including the Massachusetts State Police, U.S. Immigration and Customs Enforcement, Enforcement and Removal Operations, Suffolk County and Middlesex County District Attorney’s Offices, and the Boston, Chelsea, Everett, Falmouth, Lynn, Medford, Nantucket, and Revere Police Departments.

Assistant U.S. Attorneys Timothy Moran and Fred Wyshak of the Organized Crime & Gang Unit are prosecuting the case as part of an Organized Crime Drug Enforcement Task Forces (OCDETF) operation. The OCDETF Program uses a prosecutor-led, intelligence-driven, multi-agency approach to identify, disrupt, and dismantle the highest-level criminal organizations that threaten the United States.

Elvin Martinez-Flores is scheduled to be sentenced on Aug. 5, 2025. This case serves as a stark reminder of the dangers of fentanyl trafficking and the efforts of law enforcement agencies to combat it.
