The former leader of the Lynn Chapter of the Trinitarios gang, Aaron Diaz Liranzo, also known as "Sosa," has pleaded guilty to racketeering conspiracy charges. The plea was entered in a Boston court where U.S. Senior District Court Judge Nathaniel M. Gorton set sentencing for June 25, 2025.
Diaz Liranzo was charged with conspiracy to conduct enterprise affairs through a pattern of racketeering activity, commonly referred to as RICO conspiracy. He was arrested and charged in February 2025 while serving as the leader of the Lynn Chapter of the Trinitarios.
The Trinitarios is described as a violent criminal organization with thousands of members across the United States. The gang follows a Magna Carta and employs an internal hierarchy to organize and execute acts of violence while maintaining secrecy.
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 in Lynn in 2023. These incidents were allegedly committed by members of the Trinitarios. Diaz Liranzo is now the sixth defendant to plead guilty.
From at least 2021 through 2025, Diaz Liranzo held the position of Primera or Number One within his chapter. He admitted involvement in a March 2019 shooting targeting rival gang members outside a nightclub in Lynn. The victims had been lured there by another member posing as a woman needing assistance. Armed with knowledge about their location and vehicle, Diaz Liranzo fired six rounds at their car, injuring two individuals who survived despite life-threatening injuries.
The charge carries potential penalties including up to life imprisonment, five years supervised release, and fines up to $250,000. Sentencing will be determined based on U.S. Sentencing Guidelines and relevant statutes.
The announcement was made by United States Attorney Leah B. Foley along with officials from Homeland Security Investigations New England, FBI Boston Division, Essex County District Attorney's Office, Massachusetts State Police, and Lynn Police Department among others involved in this case's investigation.
Assistant U.S. Attorney Philip A. Mallard from the Organized Crime & Gang Unit is prosecuting this case.
All remaining defendants are presumed innocent until proven guilty beyond reasonable doubt in court proceedings.
