The former leader of the Lynn Chapter of the Trinitarios gang, Aaron Diaz Liranzo, also known as "Sosa," has pleaded guilty to racketeering charges. The plea was entered for conspiracy to conduct enterprise affairs through a pattern of racketeering activity, commonly referred to as RICO conspiracy. U.S. Senior District Court Judge Nathaniel M. Gorton has scheduled sentencing for June 25, 2025.
Diaz Liranzo was arrested and charged in February 2025 while serving as the leader of the Lynn Chapter of the Trinitarios. This criminal organization is known for its violent activities and consists of thousands of members across the United States. It follows a strict internal hierarchy and maintains secrecy among its members.
In February 2025, federal racketeering charges were unsealed against 22 leaders and members of the Trinitarios following a multi-jurisdictional investigation that began after four murders and several attempted murders and shootings occurred in Lynn in 2023. These incidents were allegedly linked to the Trinitarios criminal enterprise. Diaz Liranzo is now the sixth defendant to plead guilty.
From at least 2021 through 2025, Diaz Liranzo held a leadership position within his chapter. He admitted involvement in a March 2019 shooting targeting rival gang members outside a nightclub in Lynn. During this incident, he fired multiple rounds at a vehicle with three occupants, injuring two individuals who survived despite life-threatening injuries.
The charge carries a potential sentence of up to life imprisonment, five years supervised release, and fines up to $250,000. Sentencing will be determined by federal district court guidelines.
United States Attorney Leah B. Foley announced this development along with officials from Homeland Security Investigations New England; Federal Bureau of Investigation Boston Division; Essex County District Attorney's Office; Massachusetts State Police; and Lynn Police Department. Additional support came from various law enforcement agencies including U.S Customs and Border Protection and police departments from Andover, Boston, Lawrence, Peabody, and Salem.
Assistant U.S Attorney Philip A Mallard is handling prosecution efforts for this case underlining that all remaining defendants are presumed innocent until proven guilty beyond reasonable doubt in court proceedings.
