MS-13 Gang Leader Sentenced to 68 Years in Prison for Eight Murders, Multiple Attempted Murders, Arson, Narcotics Trafficking, and Firearms Offenses

Earlier today, in federal court in Central Islip, Alexi Saenz, also known as “Blasty” and “Plaky,” the leader of the Brentwood/Central Islip chapter of the Sailors Locos Salvatruchas Westside (Sailors) clique of La Mara Salvatrucha, also known as the MS-13, a transnational criminal organization, was sentenced by United States District Judge Gary R. Brown to 68 years’ imprisonment.  On July 10, 2024, Saenz pleaded guilty to racketeering charges in connection with his participation in eight murders, namely, the January 28, 2016 murder of Michael Johnson; the April 29, 2016 murder of Oscar Acosta; the September 5, 2016 murder of Marcus Bohannon; the September 13, 2016 murders of Kayla Cuevas and Nisa Mickens; the October 10, 2016 murder of Javier Castillo; the October 13, 2016 murder of Dewann Stacks; and the January 30, 2017 murder of Esteban Alvarado-Bonilla, in addition to his participation in three attempted murders, and arson, narcotics trafficking, and firearms offenses.   

Joseph Nocella, Jr, United States Attorney for the Eastern District of New York; Christopher G. Raia, Assistant Director in Charge, Federal Bureau of Investigation, New York Field Office (FBI New York); and Kevin Catalina, Commissioner, Suffolk County Police Department (SCPD), announced the sentence.

“Alexi Saenz led an unspeakable reign of terror, killing, and crime that damaged his community and cost several people their lives,” stated United States Attorney Nocella.  “My Office and our law enforcement partners will continue to work tirelessly to hold the MS-13 and its members accountable for their horrific acts, including the pain they’ve caused victims and their loved ones.  This sentencing is one of many in our relentless pursuit to dismantle the MS-13 and other violent criminal organizations.” 

“For years, Alexi Saenz wielded his role as a local MS-13 leader to facilitate and participate in eight brutal murders of perceived rivals. Saenz terrorized Long Island as he indiscriminately targeted and hunted a wide range of victims, with careless regard to innocent bystanders harmed by his actions. May today’s sentencing emphasize the FBI’s relentless determination to crush all gang violence plaguing our communities,” stated FBI New York Assistant Director in Charge Raia.

“Alexi Saenz is a violent career criminal whose path of destruction ripped apart families and terrorized Suffolk County with his MS-13 cohorts,” stated SCPD Commissioner Catalina.  “I commend the efforts of the SCPD officers and our law enforcement partners who are dedicated to bringing violent gang criminals to justice and offering closure to the victims’ families.”

As set forth in the government’s sentencing memorandum, prior court filings, and statements during the sentencing, Alexi Saenz was the local leader of the Brentwood/Central Islip chapter of the Sailors clique of the MS-13 – one of the more powerful, violent, and well-established cliques on the East Coast of the United States.  He committed the following crimes in order to maintain and increase his membership and status within the gang and to further the mission of the MS-13:

January 28, 2016 Murder of Michael Johnson

On January 28, 2016, Alexi Saenz and other MS-13 members and associates were at the Jocorena Deli in Brentwood, where they saw 29-year-old Michael Johnson, and claimed to recognize him as a member of the rival Bloods street gang.  At that point, Johnson was marked as their “food” – a reference to their intention to kill him. 

After receiving the requisite approval from the New York leader of the Sailors clique to commit this murder, Alexi Saenz contacted several other MS-13 members, informed them of the plan to kill Johnson, and instructed them to bring weapons, including a machete and a baseball bat, to a wooded area in Brentwood.  Alexi Saenz then lured Johnson to that secluded meeting location under the guise of smoking marijuana.  The MS-13 members and associates ambushed Johnson from behind – striking Johnson with the baseball bat, stabbing him with a knife, and taking turns hacking him with the machete.  They fled after hearing police sirens in the area.   

Johnson was reported missing by family members. Less than one week after his murder, on February 2, 2016, members of the SCPD responded to a 911 call about a body found in the woods by a passerby, and recovered Johnson’s body.  An autopsy determined Johnson’s cause of death to be sharp and blunt force injuries.   

April 29, 2016 Murder of Oscar Acosta

In early 2016, Alexi Saenz and his fellow Sailors clique members decided to “green light,” or approve, the murder of 19-year-old Oscar Acosta because they suspected that he was associating with the rival 18th Street gang after previously aligning himself with the MS-13. The New York Sailors clique leader assigned roles as to which members would take the lead in planning and carrying out the murder. 

On April 29, 2016, MS-13 members met Acosta in a wooded area near an elementary school in Brentwood where he had been lured under the guise of smoking marijuana.  They brutally beat Acosta with tree limbs, knocking him unconscious. They bound Acosta’s hands and feet, wrapped an article of clothing around his mouth to prevent him from making noise, and summoned other MS-13 members, including Alexi Saenz.  The MS-13 members loaded Acosta into the trunk of Alexi Saenz’s car, and drove to a more secluded area in Brentwood near the abandoned Pilgrim State Psychiatric Hospital.  At the direction of Alexi Saenz, the MS-13 members removed Acosta, who was still alive, from the trunk and carried him deeper into the woods where they took turns hacking him to death with a machete.  The murder was supervised by Alexi Saenz, as his role as the local clique leader.  The MS-13 members then buried Acosta’s body in a shallow grave.   

Acosta’s body was discovered by law enforcement nearly five months later, on September 16, 2016, during a search for another MS-13 victim.  His cause of death was homicidal violence, including sharp and blunt force injuries to his head and torso.

July 18, 2016 Attempted Murders of John Doe #1 and John Doe #2

On July 18, 2016, during a Sailors clique meeting at Alexi Saenz’s house in Central Islip, the defendant instructed the group to hunt for rival gang members who had been disrespectful to the MS-13, in order to attack and kill them.

Later that evening, other members of the MS-13, who were driving around Brentwood armed with firearms and a machete, spotted a group of men on Apple Street. Believing these men to be members of a rival gang, three MS-13 members got out of the car and attacked the group, firing rounds from two different guns, and then using a machete to hack at one of the men who had fallen to the ground.  After the attack, the group drove back to Alexi Saenz’s house, where they hid the weapons.

Two individuals were injured as a result of this attack.  John Doe #1 was struck with a bullet, but survived.  John Doe #2 was attacked with a machete, and was permanently disfigured.

August 10, 2016 Attempted Murders of Suspected Rival Gang Members

In 2016, members of the MS-13 were engaged in a series of disputes with members of the Goon Squad, a rival gang in Brentwood. 

On August 10, 2016, Alexi Saenz and another MS-13 member drove through the neighborhood around Lukens Avenue in Brentwood, and spotted several men who they believed were members of the Goon Squad. They then rallied other members of the Sailors clique to come kill the rivals. 

The MS-13 members divided into two vehicles, and drove towards the house where the suspected Goon Squad members had been spotted. Alexi Saenz’s car kept watch for the police, while two other MS-13 members, each bearing a gun, approached the group of suspected rivals and fired numerous shots in their direction.  No one was hit, although a stray bullet entered a neighbor’s house and struck the headboard of a bed in which the neighbor was sleeping.

September 5, 2016 Murder of Marcus Bohannon

On September 4, 2016, during a Sailors clique meeting at Alexi Saenz’s house in Central Islip, the defendant and other MS-13 members went out hunting for rival gang members to kill.

The MS-13 members separated into several cars and drove around Central Islip and Brentwood, until Alexi Saenz’s group spotted 27-year old Marcus Bohannon walking along Lowell Avenue in Central Islip in the early morning hours of September 5.  Suspecting that Bohannon was a member of the rival Bloods gang, two MS-13 members, carrying firearms, got out of the vehicle, approached him, and started shooting.  Alexi Saenz then drove them away.  Bohannon was struck nine times, including in his head, neck, and chest, and died from his wounds.

September 12, 2016 Arson

During the summer of 2016, Sailors clique members of the MS-13 engaged in regular altercations with local gang members based in a neighborhood on Freeman Avenue in Brentwood.

On September 12, 2016, MS-13 members retaliated by setting fire to a car parked in the driveway of one of the houses in that rival gang neighborhood.  Alexi Saenz directed other gang members to purchase gasoline and carry out the arson, while he drove around watching for police presence.  The other MS-13 gang members drove to that house, where they poured gasoline on a car parked in the driveway, and set it on fire.  The car exploded, and set another parked car on fire.   

September 13, 2016 Murders of Kayla Cuevas and Nisa Mickens

On September 13, 2016, Sailors clique members brutally murdered 15-year-old Nisa Mickens and 16-year-old Kayla Cuevas, both students at Brentwood High School.

In the months leading up to the murders, Cuevas was involved in a series of disputes with members and associates of the MS-13.  Approximately one week before the murders, these disputes escalated when Cuevas and several friends were involved in an altercation with MS-13 members at Brentwood High School.  After that incident, the MS-13 members vowed to seek revenge against Cuevas.

On the evening of September 13, 2016, Alexi Saenz and other members of the Sailors clique of the MS-13 were driving in separate cars around Brentwood in search of rival gang members to attack and kill.  One group of MS-13 members spotted Cuevas and Mickens walking down residential Stahley Street.  Recognizing Cuevas, they called Alexi Saenz and were granted permission to kill the girls. Several MS-13 members then chased down and attacked both Cuevas and Mickens, wielding baseball bats and a machete, striking each of the girls numerous times in their heads and bodies, while Alexi Saenz’s car drove around watching for police.  After the murders, the group retreated to Alexi Saenz’s home in Central Islip, where they changed clothes and hid the weapons.   

Mickens, whose body was discovered later that evening on Stahley Street, not far from Cuevas’s home, sustained significant sharp force trauma to her face and blunt force trauma to her head.  Cuevas, whose body was discovered the following day behind a house adjacent to where Mickens’s body was found, sustained significant blunt force trauma to her head and body and multiple lacerations.

October 10, 2016 Murder of Javier Castillo

In October 2016, the MS-13 targeted 15-year-old Javier Castillo because he was believed to be a member of the 18th Street gang, one of MS-13’s principal rivals. 

On October 10, 2016, several members of the Sailors clique convinced Castillo, who lived in Central Islip, to drive with them to Freeport – approximately 30 miles away – to smoke marijuana.  Once there, they met Alexi Saenz and other Sailors clique members.  The group then lured Castillo to an isolated marsh area in Cow Meadow Park, where they attacked him, taking turns hacking him to death with a machete. 

Afterwards, the MS-13 members dug a hole and buried Castillo’s body, which was not recovered until one year later, in late October 2017.  Castillo was determined to have suffered multiple sharp force injuries to his head, neck, torso, and extremities.

October 13, 2016 Murder of Dewann Stacks

On the evening of October 13, 2016, Alexi Saenz and other members of the Sailors clique of MS-13 were driving around Central Islip and Brentwood in search of rival gang members to attack and kill.

That night, they spotted 34-year-old Dewann Stacks and, believing him to be a rival gang member, Alexi Saenz authorized his murder.  While Alexi Saenz drove around watching for police presence, another group of MS-13 members, armed with two machetes and a baseball bat, drove over to attack Stacks.  Three armed MS-13 members got out of the car, and beat and hacked Stacks to death on American Boulevard, a residential street in Brentwood.  Stacks sustained severe sharp and blunt force trauma to his face and head, leaving his body nearly unrecognizable.

January 30, 2017 Murder of Esteban Alvarado-Bonilla

On the morning of January 30, 2017, Alexi Saenz and other members of the Sailors clique of MS-13 spotted 29-year-old Esteban Alvarado-Bonilla inside El Campesino Deli in Central Islip.  Since Alvarado-Bonilla was wearing a football jersey bearing the number “18,” the MS-13 concluded that he was a member of a rival gang and plotted to kill him.

Several other MS-13 members obtained a mask and another vehicle that would be used to commit the murder.  Alexi Saenz provided the clique’s 9-millimeter handgun for use in the murder.

At approximately 10:30 a.m., a masked MS-13 member entered the deli, approached Alvarado-Bonilla from behind, and shot him multiple times, killing him.  One of the bullets pierced through Alvarado-Bonilla’s head and struck the chest of a female employee of the deli, who was standing directly in front of him.  The deli employee survived the gunshot wound.   

Narcotics Trafficking Conspiracy

For a year and a half, from approximately April 2016 through March 2017, in order to finance the illegal operations of the Sailors clique, Alexi Saenz obtained wholesale quantities of cocaine and marijuana, which he distributed to other Sailors clique members and associates for street-level sales in Brentwood and its surrounding areas.  After the sales, the profits were turned over to Alexi Saenz, for use in, among other things, purchasing firearms for use by clique members, wiring money to MS-13 leaders in El Salvador, and buying additional narcotics for further distribution.

Today’s sentencing is the latest achievement in a series of federal prosecutions by the United States Attorney’s Office for the Eastern District of New York targeting members of the MS-13, a violent, transnational criminal organization.  The MS-13’s leadership is based in El Salvador, Honduras, Guatemala, and Mexico, but the gang has thousands of members across the United States.  With numerous branches, or “cliques,” the MS-13 is the most violent criminal organization on Long Island.  Since 2003, hundreds of MS-13 members, including dozens of clique leaders, have been convicted on federal felony charges in the Eastern District of New York. A majority of those MS-13 members have been convicted on federal racketeering charges for participating in murders, attempted murders, and assaults.  Since 2010, this Office has obtained indictments charging MS-13 members with carrying out more than 75 murders in the Eastern District of New York, resulting in the convictions of dozens of MS-13 leaders and members in connection with those murders.  These prosecutions are the product of investigations led by the FBI’s Long Island Gang Task Force, which is comprised of agents and officers of the FBI, SCPD, Nassau County Police Department, Nassau County Sheriff’s Department, Suffolk County Probation Office, Suffolk County Sheriff’s Office, the New York State Police, the Hempstead Police Department, the Rockville Centre Police Department, and the New York State Department of Corrections and Community Supervision.

The case is part of Operation Take Back America, a Department of Justice initiative aimed at eradicating transnational criminal organizations, combating violent crime, and restoring the rule of law.

This prosecution is also part of an Organized Crime Drug Enforcement Task Forces (OCDETF) investigation.  OCDETF identifies, disrupts, and dismantles the highest-level drug traffickers, money launderers, gangs, and transnational criminal organizations that threaten the United States by using a prosecutor-led, intelligence-driven, multi-agency approach that leverages the strengths of federal, state, and local law enforcement agencies against criminal networks.

The government’s case is being handled by the Criminal Section of the Office’s Long Island Division.  Assistant United States Attorneys John J. Durham, Paul G. Scotti, Justina L. Geraci, and Megan E. Farrell are in charge of the prosecution, with the assistance of Paralegal Specialist Kerryanne Ucci and Automated Litigation Specialist Michael Compitello.
