Late on June 20th, 2018, a teenage boy named Lesandro Jr. Guzman-Feliz entered the Bronx bodega on East 183rd Street. He was breathing heavily and looking over his shoulder. People inside the store noticed the panic on his face. Moments earlier, several cars had pulled up outside.
Doors open and figures stepped out moving with clear purpose. Some had their faces covered and carried long blades low at their sides. Junior tried to hide behind the counter. The store owner hesitated. The door burst open and several men rushed inside, grabbed him, and dragged him back out into the street.
This incident did not begin that night. To understand how it unfolded, it is necessary to examine events that started years earlier inside Rikers Island. In the early 1990s, Dominican inmates faced pressure from multiple established prison groups that already controlled numbers, structure, and territory. In 1993, two inmates named Leonides Unitos Sierra and Julio Caballo Marinez decided to organize a more disciplined group.
Scattered individuals had been easy targets in that environment. Their goal at the start was unity and protection. Dominican prisoners needed safeguards for daily movement, food access, and basic survival inside the jail system. What began as a defensive effort gradually became more organized.
Sierra ran the group with a clear chain of command modeled on military structure rather than loose street behavior. Sierra positioned himself as supremo. Orders came from him through selected lieutenants who enforced discipline among members even while everyone remained incarcerated. Refusal to follow instructions carried immediate consequences.
This created a culture in which loyalty was expected. The name Trinitarios came from Dominican history and referred to three revolutionaries. It gave members a sense of identity connected to heritage instead of random street affiliation. Colors included lime green along with red, white, and blue from the Dominican flag.
The slogan Dios, Patria, y Libertad provided a symbolic foundation that extended beyond simple prison survival. As members completed their sentences and were released, the same structure moved outside the prison walls. The organization did not reset upon release. It expanded into neighborhoods that already dealt with gang tension.
Sierra maintained influence from behind bars. He passed instructions through trusted members who acted as a central committee controlling activity across boroughs. This continuity allowed the group to grow rapidly. Leadership never disappeared. It operated through different channels that remained connected to the original framework.
While the initial goal centered on protection, the methods used to enforce discipline revealed a different pattern. Violence became a tool that kept the system intact. The early phase showed that the group was not simply another neighborhood crew trying to survive tough conditions. The structure rewarded aggression and punished hesitation.
This shaped how members operated once they reached the streets. Over time, the line between defense and domination became less clear. The same system that provided protection also gave members the ability to control territory if they chose to expand. By the time the first Trinitarios members left Rikers Island and entered New York streets in the late 1990s and early 2000s, the foundation they carried already leaned toward more than protection alone.
Once those members returned to the streets, the Trinitarios did not operate as a loose group. They already had a structure that allowed quick organization across the Bronx and Upper Manhattan. Neighborhoods with strong Dominican populations served as natural hubs. Cultural identity helped with recruitment and brought in younger members.
Instead of functioning as one single unit, the gang divided into cliques that followed the same hierarchy. This allowed leadership to control different areas without losing overall coordination. The setup made expansion easier. Each clique handled local operations while still answering to higher authority figures linked back to Sierra’s original framework.
As numbers grew, enforcement rules became stricter. Maintaining discipline across multiple boroughs required both fear and loyalty. Punishments for disobedience were often violent and public enough to send a clear message. Members who stepped out of line faced beatings or worse. This reinforced the idea that joining was a full commitment.
With that control in place, criminal activity expanded beyond survival into profit-driven operations. These included robberies, drug distribution, and coordinated assaults that strengthened their presence on the streets. Law enforcement began noticing patterns. Incidents involving Trinitarios members showed organization rather than random acts.

This raised concern among federal agencies tracking gang activity in New York. One detail that stood out was their choice of weapons. Machetes and large knives became a signature tied to their identity. These weapons made attacks more brutal and set the group apart from crews that relied mainly on firearms.
The choice carried psychological weight. Victims often described the attacks as more personal. By the early 2010s, reports described the Trinitarios as one of the fastest growing Caribbean gangs in the United States. Membership spread into states such as New Jersey, Massachusetts, and Pennsylvania. Federal authorities later stated that thousands of members were active across the East Coast.
This showed how far the group had come from its origins inside Rikers Island. As their reputation grew, so did their willingness to act aggressively in both rival conflicts and internal enforcement. Violence was no longer only a response. It became a strategy used to maintain dominance in contested areas. This marked a clear change from the original purpose.
Protection was no longer the main focus. Control became the goal that guided their actions. As the Trinitarios continued expanding across New York into the late 2000s, federal investigators noticed patterns pointing to organized activity rather than random street crime across borough lines.
Between 2009 and 2011, the US Attorney’s Office in Manhattan built racketeering cases under the RICO statute. These cases targeted a coordinated network tied directly to Bronx Trinitarios leadership. More than 50 members face charges involving narcotics distribution, firearms possession, and violent assaults linked to gang activity across the tri-state area.
By the time convictions accumulated, over 140 individuals connected to the organization received lengthy prison sentences. Law enforcement expected this would weaken the structure permanently. That expectation did not fully materialize. Leonides Junito Sierra remained active from behind bars.
He continued to influence decisions through a chain of trusted members who relayed instructions back to the streets. Even after receiving an additional federal sentence in 2014 tied to racketeering, Sierra still carried weight inside the system he had built. Leadership never completely disappeared. This continuity allowed the Trinitarios to adjust quickly.
Removing older figures created openings that younger members stepped into. Instead of slowing down, new faces took on roles that came with pressure to prove themselves. This often pushed them toward more aggressive behavior in order to earn respect. While arrests removed key figures, the environment on the streets did not calm as authorities had expected.
Activity continued across the Bronx and upper Manhattan with similar patterns of violence and organized movement. The gang adapted by decentralizing certain operations. This made it harder for law enforcement to track decisions back to a single leader. Multiple cliques operated with partial independence.
That shift created a situation where control became less centralized. It brought its own problems because different crews started interpreting orders in their own ways. As a result, leadership changes did not bring stability. Instead, they introduced tension that slowly built beneath the surface while the gang kept moving.
As that internal pressure grew, the Trinitarios began splitting into factions that no longer moved with the same unified direction. Divisions formed around territory, leadership style, and personal loyalty. One group known as Los Sures had roots in Brooklyn’s Sunset Park community. Another faction called Sunset formed around Bronx members who broke away during disputes over control.
Those names sounded similar, yet represented opposing sides within the same identity. This made the conflict more complicated because both claimed legitimacy under the Trinitarios banner. Tension increased when leaders attempted to expand influence into areas already controlled by other cliques. Friction quickly moved beyond conversation into confrontation.
By the mid-2010s, disagreements over authority turned into open hostility. Neither side wanted to step back from territory that brought both reputation and financial opportunity through street-level operations. Members who once operated under the same rules now viewed each other with suspicion. Loyalty lines blurred because alliances shifted depending on who held power at a given moment.
Smaller incidents, including personal disputes or social media arguments, began triggering larger responses. Each side interpreted actions as disrespect that needed to be addressed publicly. This environment made retaliation more frequent. Every move risked being answered with something heavier, which kept the cycle moving.
Violence inside the organization became as intense as conflicts with outside rivals. Attacks between factions followed the same patterns used against other gangs, including coordinated group actions and targeted assaults. This shift showed how far things had moved from the original structure. Unity no longer defined the Trinitarios.
Internal competition started shaping behavior instead. Younger members coming into that environment had to navigate shifting alliances. Survival depended on reading situations quickly while staying aligned with whoever held influence locally. Over time, that instability created a setting where identity alone did not guarantee safety.
Being part of the same gang no longer protected individuals from becoming targets. As those divisions deepen, the streets became harder to predict. Violence could come from expected rivals or from within the same organization without much warning. What started as disagreements over control evolved into a situation where anyone moving through the wrong area at the wrong moment could be seen as an enemy, even if they shared the same colors or background.
This unpredictability set the stage for later events. A system built on loyalty had turned into one where mistakes carried serious consequences. As internal conflict kept building, a term started circulating more often among Trinitarios members, casando. The word translates directly from Spanish into hunting.
Within their circle, it carried a specific meaning tied to action on the streets. When leaders used that word, it signaled that members were expected to move out actively looking for rivals rather than waiting for problems to come to them. This turned violence into something planned ahead of time. Crews prepared themselves mentally before stepping into cars with a clear objective already in place.
Communication around Kasandra stayed simple but effective. A single message from someone higher up could mobilize multiple members within minutes without long discussions. As the system developed, groups would ride together through neighborhoods and coordinated convoys. They often used two or more vehicles to move through areas associated with rival factions, especially zones tied to the Bronx-based Sunset Crew.
Before leaving, members armed themselves with machetes, large knives, and whatever else they could carry easily. Those weapons had already become part of their identity during earlier years. Leadership figures like Diego Suero, who held the title of first Duarte within the Bronx Trinitarios, played a central role in organizing these movements.
His position allowed him to give direct instructions that others followed without hesitation. His second in command, Frederick Collazo, then often supported those decisions. This created a chain of authority that ensured orders reached the crews heading out on these rides. Target selection during these operations rarely relied on confirmed identification.
Members often acted based on appearance, location, or assumption tied to territory known for rival presence. If someone looked like they belonged to the opposing faction or happened to be in a contested area, that alone could be enough to trigger an attack. This approach made the outings extremely dangerous for anyone nearby.
Leading up to June 2018, several incidents showed how quickly situations escalated under this approach. Minor disagreements could lead to serious violence once the idea of hunting took hold within the group. One example involved a dispute between teenagers connected through social media.
An argument over a girl led to a targeted stabbing of a 14-year-old boy on June 18th, 2018 near the Bronx River Parkway. That earlier attack, although not fatal, revealed how the mindset had shifted. Something that could have ended as a simple argument instead turned into a coordinated assault meant to send a message across factions.
Members interpreted these situations as opportunities to assert dominance rather than resolve issues. This reinforced the idea that action had to be immediate and visible. Over time, this created a culture where violence was no longer reactive. Instead, it became proactive. Crews actively searched for chances to strike before being challenged themselves.
By the time June 20th arrived, the structure, leadership, and mindset behind Kazondo had already set the stage for the events that followed. On the evening of June 20th, 2018, the system moved into motion again. Diego Suero gathered a group of Trinitarios members inside his Bronx apartment. The conversation quickly turned toward ongoing conflict with the Sunset faction.
During that meeting, according to later testimony from cooperating witnesses, Suero made it clear that members needed to take action that night. He told them to handle any rivals they came across while moving through the neighborhood. That message, aligned directly with the Kazondo approach already used in previous days, everyone understood what was expected before leaving the apartment.
Once the meeting ended, multiple vehicles formed up outside. Members split into groups that would move together through areas associated with their rivals. As those cars began driving through Belmont and surrounding blocks, the atmosphere inside each vehicle stayed focused.
Everyone involved knew the purpose of the ride without needing further explanation. Around 11:30 p.m., the convoy spotted a teenage boy walking alone near East 183rd Street and Bathgate Avenue. Attention shifted toward him almost immediately. That boy was Lesandro Junior Guzman-Feliz, a 15-year-old who had no connection to any gang activity.
His presence in that location placed him directly in the path of the group. Some members believed he matched the description of someone tied to the rival faction. Others simply reacted to the opportunity presented in that moment without verifying who he actually was. As the vehicle slowed, Junior noticed something was off.
He started running down the street trying to create distance between himself and the approaching cars. That reaction confirmed the group’s suspicion in their minds. Movement like that was often interpreted as someone trying to escape recognition. The chase moved quickly through the block. Junior ran toward a nearby bodega on the corner hoping to find safety inside a place where people were present.
When he entered the store, he rushed behind the counter. The owner and others inside struggled to understand why he looked so desperate and why multiple individuals were closing in from outside. Within seconds, several members forced their way into the bodega. Kevin Alvarez, who had been driving one of the vehicles involved in the chase, grabbed Junior and began pulling him toward the door.
Others inside the store reacted with confusion mixed with fear. The situation had escalated faster than anyone could process. Junior resisted, holding onto the counter and door frame. The group’s momentum carried him outside onto the sidewalk, where more members waited with weapons already drawn. Among them was Jon Ieki Martinez Estrella, who later became identified as the individual responsible for delivering the most severe injury during the attack.
What followed happened in a matter of seconds. Multiple attackers struck Junior with knives and machetes while he was on the ground. This left him critically wounded before the group quickly dispersed back into their vehicles. Once the group left the scene, Junior managed to stand up and move back inside the store. He attempted to find help despite the severity of his injuries.
He then exited again, trying to reach Saint Barnabas Hospital, located a short distance away. He collapsed near the street corner before making it inside. Witnesses attempted to assist him while emergency services were called. The injuries proved too severe and he died shortly after. As details began to emerge, it became clear that Junior had no connection to the intended targets of that night’s operation.
The group had attacked the wrong person based on assumption rather than confirmation. This realization changed the way the incident was viewed. What started as another Cazzando outing turned into a case that exposed how dangerous the system had become when identity was reduced to guesswork. As news of the attack spread across the Bronx that same night, surveillance footage from inside the the began circulating online within hours.
It showed exactly how events unfolded in a way that was hard to ignore. Once the video reached social media platforms, people across New York started reacting. The hashtag justice for Junior started trending. Thousands of posts called attention to what happened to Lesandro Guzman-Feliz. Users shared clips, photos, and details that pushed the story beyond local coverage.
Public interest kept building as more people saw the footage. The brutality, combined with the victim’s age, made the situation stand out across communities. Junior’s family stepped forward. His mother, Leandra Guzman, spoke publicly about her son while demanding accountability for those involved in the attack.
Community members gathered near East 183rd Street and Bathgate Avenue. They left candles, flowers, and messages that turned the area into a memorial reflecting both grief and concern. His funeral drew large crowds including local officials and residents who wanted to show support.
This reinforced how widely the story had spread beyond the neighborhood. Media outlets across the country picked up the case. National attention kept pressure on authorities to act quickly rather than treat it as a routine investigation. That level of visibility created urgency for law enforcement. The volume of public interest meant delays would only increase criticism.
This pushed agencies to prioritize identifying everyone involved. Tips continued coming in through hotlines and social media. Investigators began moving fast. The attention surrounding the case made it clear that arrests needed to happen without delay. The NYPD worked alongside federal agencies, including the FBI, to coordinate efforts.
They combined surveillance footage with witness statements to build a clear picture of what happened on June 20th, 2018. Detectives analyzed video from the bodega along with nearby cameras. This allowed them to track movements of the vehicles used during the incident. It led to the identification of several individuals connected to the attack.
Tips from the public played a major role. The widely shared footage helped people recognize faces, vehicles, and locations tied to suspects who had tried to leave the area after the crime. Within days, arrests began taking place across New York, New Jersey, and Connecticut. Law enforcement tracked down members involved in the Kazondo operation that night.
Among those taken into custody were Kevin Alvarez, who drove one of the vehicles, along with Jonaiki Martinez Estrella, later identified as the person responsible for delivering the fatal wound. Investigators also connected Diego Suero and Frederick Colita then to the case.
They uncovered their roles in organizing the operation through testimony and evidence gathered during the investigation. As more suspects were brought in, authorities were able to map out how each participant contributed, from drivers and spotters to those directly involved in the attack itself. As the case developed, some individuals chose to cooperate with prosecutors.
They provided details about what happened before and during the incident in exchange for reduced charges. This strengthened the overall case against the group. Witness testimony, including statements from those inside the bodega and individuals connected to the gang helped confirm identities while establishing the sequence of events leading up to the attack.
Inside the Trinitarios, that cooperation created tension. Members viewed anyone speaking to law enforcement as a traitor under internal rules that carry serious consequences. That mindset was tied to what members referred to as code 357, a directive stating that anyone labeled a snitch should be targeted.
This added another layer of pressure for those considering cooperation. As prosecutors built their case, it became clear that this situation extended beyond a single act of violence. The investigation revealed a structured system involving leadership decisions, coordinated movement, and a pattern of similar incidents.
What started as one killing quickly turned into a broader examination of how the Trinitarios operated. The events of that night were part of a larger system already in place. As the investigation moved into the courtroom, proceedings began in 2019. Prosecutors presented evidence that tied each defendant to specific roles during the events of June 20th, 2018.
They used surveillance footage, phone records, and witness accounts to build a clear timeline. One of the most important shifts came when Kevin Alvarez agreed to cooperate. His testimony gave jurors direct insight into how the group organized that night under instructions connected to Diego Suero. Alvarez described how members gathered earlier that evening, how vehicles were assigned, and how the group moved through the Bronx while looking for targets.
This helped prosecutors connect actions on the street back to leadership decisions. His cooperation carried weight. He identified individuals involved while explaining how the Kazando system worked in real situations rather than theory. As trials continued, juries found multiple defendants guilty of charges including first-degree murder, second-degree murder, and gang-related enhancements.
Jonaiki Martinez Estrella was identified as the person who delivered the fatal injury to Lesandro Guzman-Feliz. Sentences followed in stages. Martinez Estrella initially received life without parole. Others such as Jose Muniz, Antonio Rodriguez, Hernandez Santiago, Elvin Garcia, and Manuel River received sentences ranging from 23 years to life up to 25 years to life.
During sentencing, Junior’s mother, Leandra Guzman, addressed the court directly. She described the impact of losing her son while asking that those responsible never return to the all streets. This added emotional weight to decisions already grounded in evidence. In later proceedings, Diego Suero, along with Frederick Coleta, then faced trial for their roles in organizing the attack.
Both were convicted of second-degree murder plus conspiracy charges in 2022. They received sentences of 25 years to life. By early 2023, prosecutors confirmed that all individuals charged in connection with the case had been convicted or resolved through plea agreements. This closed out the legal process that followed Junior’s death.
Inside prison, dynamics shifted for those convicted. Several faced threats from other inmates while others dealt with consequences tied to internal gang rules, especially for those who cooperated with authorities. In June 2025, Jonaiki Martinez Estrella was found dead in his cell at Coxsackie Correctional Facility at age 31.
Officials reported that emergency responders attempted to revive him, while the exact cause remained under review. Reports suggested a possible overdose. That development added another layer to a case that had already drawn national attention. One of the central figures would not serve out his full sentence.
While the legal chapter reached a conclusion, questions remain about how a system like this continued operating long before that night, and what conditions allowed it to grow. While the case surrounding Junior’s death exposed one part of the Trinitarios, investigations across the 2020s revealed that the organization had expanded into a broader network involving drug trafficking, financial crimes, and multi-state operations that extended beyond New York City.
Federal cases showed members moving fentanyl between states like Massachusetts and New York. Individuals such as Wilvin Rosario Martinez were linked to distributing thousands of counterfeit pills alongside illegal firearms. Those operations demonstrated how the group adapted over time. They shifted into markets that generated significant profit while maintaining the same structure that supported street-level activity.
At the same time, authorities uncovered involvement in fraud schemes. This included a 2023 operation in Spain where dozens of Trinitarios members were arrested for stealing hundreds of thousands of euros through online banking scams using stolen data. That case showed how the organization operated internationally. They used technology alongside traditional street methods to fund activities ranging from legal defense to weapons purchases.
Back in the United States, further indictments in places like New England tied Trinitarios members to multiple murders plus attempted killings connected to control of drug distribution networks. This reinforced that their reach extended far beyond a single borough. Even with major arrests and convictions, smaller groups connected to the Trinitarios remained active in parts of the Bronx and upper Manhattan into the mid-2020s.
Increased law enforcement attention limited their ability to operate openly. Community organizations, along with local leaders, worked to prevent younger individuals from joining by offering alternatives. They also supported families affected by violence tied to gang activity. Junior’s mother became an advocate for change.
She pushed for measures like emergency alert systems in bodegas to improve safety in situations similar to what happened in 2018. Looking back, the trajectory of the Trinitarios shows how a group formed for protection inside Rikers Island developed into a network capable of organized violence across multiple states.
It was driven by structure, identity, and evolving criminal strategies. What happened on June 20th, 2018 did not come from a single decision. It reflected years of growth shaped by leadership choices, internal conflict, and a system that rewarded aggression over restraint. Even after key figures were removed, the underlying conditions that allowed that system to exist did not disappear entirely.
The impact continues beyond the individuals directly involved.
