BOSTON – The former leader of the Lynn Chapter of the Trinitarios gang pleaded guilty today to racketeering charges.
Aaron Diaz Liranzo, a/k/a “Sosa,” 26, pleaded guilty to conspiracy to conduct enterprise affairs through a pattern of racketeering activity, more commonly referred to as RICO conspiracy. U.S. Senior District Court Nathaniel M. Gorton scheduled sentencing for June 25, 2025. Diaz Liranzo was arrested and charged in February 2025 at which time he was the Leader of the Lynn Chapter of the Trinitarios.
The Trinitarios is a violent criminal enterprise comprised of thousands of members across the United States. The Trinitarios adhere to a Magna Carta, employ an internal hierarchy to or organize and execute violence, and undertaken extensive efforts to maintain the secrecy of the organization and its members.
In February 2025, federal racketeering charges were unsealed against 22 leaders and members of the Trinitarios. The charges were the result of a multi jurisdictional investigation, which began in the aftermath of four murders as well as a series of attempted murders and shootings that took place in Lynn in 2023, allegedly committed by the Trinitarios criminal enterprise and its members. Diaz Liranzo is the sixth Defendant to plead guilty.
During a period from at least 2021 through 2025, Diaz Liranzo served as the Primera or Number One of the Lynn Chapter of the Trinitarios. Diaz Liranzo admitted to participating in a shooting that took place in March 2019 that targeted multiple rival gang members outside of a Lynn nightclub. The victims were lured there by another member, who posed as a woman who needed a ride. Equipped with a firearm and knowledge of the victims whereabouts and vehicle they were driving, the defendant travelled to the nightclub and opened fire at the vehicle, discharging at least six rounds. During the incident, Diaz Liranzo shot two of the three victims seated in the car. Both victims suffered life-threatening injuries, but ultimately survived the incident.
The charge of conspiracy to conduct enterprise affairs through a pattern of racketeering activity (also known as “racketeering conspiracy” or “RICO conspiracy”) provides for a sentence of up to life in prison, five years of supervised release and a fine of up to $250,000. 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.
