On the night of September 13th, 2016, a dark car rolled slowly along Stahli Street in Brentwood, New York, while two teenage girls walked home talking about regular school drama. Before either one realized what was happening, doors opened fast. Several young dudes rushed out carrying baseball bats alongside a machete.
Then the whole block turned chaotic within seconds. One girl broke toward a backyard behind Ray Court, while the other stumbled near the curb after the first swings landed. Yet the crew kept pressing forward like they already knew exactly who mattered. By the following, detectives were staring at one of the ugliest murder scenes Long Island had seen in years.
Although that attack started with a school argument, the real story had already been building across Brentwood for a long time. Brentwood sat less than 50 miles from Manhattan, though most outsiders pictured the place like another quiet Long Island suburb where working families stayed out of the way after dark.
During the 2000s, thousands of immigrants from El Salvador, Honduras, Guatemala, plus other Central American countries started filling apartment houses across Brentwood and nearby Central Islip searching for work, safety, or simply another chance. That shift changed the schools fast, especially Brentwood High School, where hallways became packed with teenagers carrying trauma from places already shaped by gangs, extortion, disappearances, or civil war stories brought from back home. While teachers struggled to keep order across a campus holding more than 4,000 students, young MS-13 members quietly started turning cafeterias, stairwells, gym areas, plus social media pages into places where disrespect could carry dangerous consequences. Kayla Cuevas grew up inside that atmosphere,
although friends remembered her more for basketball games, loud jokes, stubborn arguments, plus walking everywhere alongside her closest friend, Nisa Mickens. Nisa was only 15 years old during September 2016, though her 16th birthday sat less than 24 hours away from the night everything collapsed around both families.
The girls moved together almost daily around Brentwood, which meant classmates constantly saw them heading through neighborhoods, posting online, joking after school, or standing outside stores before walking home together. While Nisa mostly stayed away from serious drama around the school, Kayla carried herself differently, partly through confidence, partly through refusing intimidation from students connected to the Sailors Clique of MS-13.
People around Brentwood High later described Kayla as somebody who talked back whenever gang-affiliated boys tried embarrassing girls inside crowded hallways, which slowly placed attention on her name throughout certain circles. Evelyn Rodriguez, Kayla’s mother, repeatedly complained to school officials after hearing threats involving knives, online harassment, stolen belongings, plus students throwing throat-slashing gestures toward her daughter between classes.
During summer school in 2016, one student reportedly threatened Kayla using a knife, although Evelyn later claimed administrators promised the situation would be handled before seeing the same student return afterward. While those complaints kept piling up, many students already understood Brentwood High had changed into a place where certain kids avoided particular colors, shoes, symbols, or even random eye contact just to avoid unwanted attention.
Around the same period, another Brentwood teenager named Elena was already getting dragged deeper into MS-13 culture through her relationship with a member called Carlos, who slowly turned controlling after first presenting himself like another regular high school dude. Carlos had friends following Elena through school corridors, taking pictures whenever she spoke with other boys, while messages threatening her parents started reaching her phone after arguments turned ugly. Those situations mattered around Brentwood during 2016 since students constantly watched rumors spread through Facebook pages, hallway gossip, neighborhood conversations, plus private group chats connected to clique members. Kids learned quickly that certain conflicts no longer ended inside school buildings once dismissal bells rang during the afternoon. That pressure sat heavy across Brentwood
High by late 2016 after several teenagers connected to gang violence had already disappeared or turned up dead around Suffolk County. Oscar Acosta vanished months before Kayla and Nisa were killed after Sailors clique members lured him into wooded areas near Pilgrim State Psychiatric Hospital, where prosecutors later said he was hacked apart before getting buried.
Jose Pena-Hernandez disappeared during the summer of 2016. then investigators eventually discovered his s- skeletal remains after searching wooded locations tied to MS-13 killings spreading through Brentwood and Central Islip. Stories like those traveled fast among students, which created an atmosphere where some teenagers stopped trusting police completely, while others became terrified of speaking openly inside classrooms.
Kayla still kept pushing back during confrontations involving gang-affiliated students, which gradually transformed ordinary school arguments into something far uglier behind closed doors. Some classmates later claimed online exchanges kept escalating after hallway disputes, embarrassed certain Sailor Clique associates connected to Brentwood High School.
Others remembered hearing whispers that Kayla laughed off threats instead of backing down quietly as gang members expected from frightened students around the neighborhood. By early September 2016, people around the Sailor’s Clique had already started talking about Kayla as if she had crossed the line.
By the time Kayla Cuevas started arguing with gang-affiliated students around Brentwood High School, people across Central Islip already knew the name Alexis Science carried serious weight around the Sailor’s Clique. Younger members called him Blasty or Plucky, while others around the neighborhood simply referred to him as the big homie controlling missions across Brentwood streets.

Alexis was only 22 years old during 2016, though federal investigators later described his clique like one of the most violent MS-13 groups operating anywhere along the East Coast. His younger brother, Jairo Science, known around the set as Funny, moved right beside him through nearly every operation, which turned both brothers into the center of several killings spreading through Suffolk County.
Alexi originally came from El Divisadero in Morazan, El Salvador, where civil war scars still shape neighborhoods years after official fighting supposedly ended during the early 1990s. That environment mattered around Brentwood since many MS-13 recruits arriving from Central America already grew up around extortion crews, disappearances, armed soldiers, plus gang culture becoming normal daily life.
After settling around Central Islip, Alexi eventually stepped deeper into the Sailors Locos Salvatruchas Westside clique while violence slowly became the fastest route towards status inside local MS-13 circles. Detectives later described meetings happening inside the Sayans brothers house where clique members discussed enemies, weapons, retaliation missions, plus who needed permission before carrying out murders around Brentwood.
That atmosphere pushed younger members into proving themselves constantly, which partly explains why killings started piling across Long Island during 2016 with terrifying speed. Earlier that year, Sailors clique members targeted 29-year-old Michael Johnson after alluring him into wooded areas under the excuse of smoking marijuana together away from crowded neighborhoods.
Once Johnson reached the location, clique members attacked him with machetes while others watched nearby turning his murder into another brutal example of how Sailors members earned approval from leadership. Stories like that spread quickly through Brentwood. Although fear kept many residents quiet whenever bodies appeared around wooded sections near Pilgrim State Psychiatric Hospital or isolated roads near Central Islip.
Only months later, 19-year-old Oscar Acosta got dragged into the same nightmare after Sailors members accused him of connections to the rival 18th Street gang operating nearby. Nelson Argueta Quintanilla joined several clique members who first beat Acosta using tree limbs before tying his hands, forcing him alive into a vehicle trunk, then driving toward abandoned woods near Pilgrim State.
Prosecutors later explained how the crew stabbed Acosta repeatedly with machetes before burying him inside a shallow grave hidden beneath dirt, branches, plus leaves across the property. While Brentwood families searched for missing teenagers during spring and summer 2016, Alexis Science allegedly bragged privately about killings connected to his clique, like violence itself became neighborhood currency.
That same pattern kept repeating around Brentwood through summer 2016 after 18-year-old Jose Pena-Hernandez disappeared without relatives immediately understanding he had already become another target connected to MS-13 discipline. Investigators later discovered skeletal remains tied to Pena-Hernandez during searches involving several missing teenagers linked back to the Sailors clique operating around Central Islip.
Around schools, rumors about disappearances mixed with hallway gossip involving gang recruitment threats, plus students terrified that somebody could accuse them of disrespecting clique members publicly. While teachers struggled to control overcrowded classrooms, clique associates moved comfortably through hallways already shaped by intimidation, which slowly normalized violence around teenagers who should have been worrying about basketball games or graduation plans instead.
Then, September 2016 arrived bringing another wave of killings directly before Kayla Cuevas and Nisa Mickens crossed paths with the Sailors clique themselves. On September 5th, Marcus Bohanan was shot nine times around Lowell Avenue after clique members targeted him during another violent mission connected to rival gang suspicions around Central Islip.
Only weeks later, 15-year-old Javier Castillo trusted several Sailors members enough to ride toward Cal Medow Park in Freeport, believing they were simply hanging out together for the night. Once Castillo reached isolated marshland areas, prosecutors said Alexis Science joined other clique members attacking the teenager with machetes before burying his body inside a hidden grave discovered much later.
Three days after Castillo disappeared, another man named DeJuan Stacks became trapped inside the same cycle after Sailors members spotted him walking through Brentwood during one of their nighttime hunts for rivals. Clique members assumed Stacks belonged to another gang, so Alexis allegedly approved another attack before several young members jumped out carrying machetes alongside baseball bats.
Medical examiners later described Stacks’ injuries as so severe that parts of his face became almost impossible to recognize properly after the beating ended near American Boulevard. Those killings mattered deeply around Brentwood during the fall of 2016 since residents slowly realized these attacks were no longer isolated incidents involving random arguments between neighborhood crews.
That fear only intensified after Estaban Alvarado Bonilla entered El Campesino Deli in January 2017 wearing a football jersey displaying the number 18 across the front. According to prosecutors, Alexi Saenz spotted the jersey, interpreted it as support for the 18th Street gang, and then approved another retaliation mission almost immediately afterward.
A masked gunman eventually entered the Deli carrying a 9-mm handgun before shooting Alvarado Bonilla multiple times while innocent customers stood nearby during the chaos. Even though that killing happened months after Kayla and Nisa died, investigators later tied the same atmosphere directly back to the Sailors Clique culture already consuming Brentwood throughout 2016.
All those murders built the exact reputation surrounding Alexi Saenz before Kayla Cuevas ever became part of the story, which explains why school arguments around Brentwood High eventually turned dangerous far beyond ordinary teenage drama. Inside the Sailors Clique, public disrespect could easily become treated like a challenge demanding retaliation, especially once social media posts, hallway arguments, plus gossip reached younger members desperate to impress leadership figures. Kayla kept arguing back anyway while some clique associates reportedly felt embarrassed after confrontations connected to school disputes spread Brentwood during late summer 2016. By the second week of September, the argument at school was no longer staying inside the school. After the arguments inside Brentwood High started spreading through
Facebook pages, hallway gossip, plus neighborhood conversations, Kayla Cuevas slowly became a familiar name around younger Sailors Clique members connected to MS-13. Students later remember seeing tensions build during summer school after confrontations involving gang-affiliated boys, while others described online exchanges turning uglier each week across social media posts circulating around Brentwood.
Some rumors claimed Kayla mocked certain clique members publicly after school disputes embarrassed them in front of classmates. Although nobody fully agreed on which argument finally pushed everything over the edge. What stayed consistent across nearly every version was that Kayla refused to act scared afterward.
While several clique associates reportedly viewed that attitude like public humiliation needing retaliation. Inside Brentwood during 2016, disrespect carried a dangerous meaning once MS-13 members believed somebody challenged their authority openly around peers, especially when social media kept replaying arguments long after school hours ended.
Younger clique associates already watched the Lexi Blood Science approve murders tied to smaller conflicts involving rival suspicions, street rumors, plus random encounters around Central Islip and Brentwood. That reputation shaped how members reacted after the school confrontation involving Kayla, partly through fear of appearing weak, partly through pressure to prove loyalty around older clique leadership.
Around the second week of September, several Sailors members reportedly started talking openly about putting a green light on Kayla, which basically meant permission to hunt her down whenever an opportunity appeared. September 13th, 2016, eventually became that opportunity after several Sailors clique members started driving around Brentwood searching for rivals during another nighttime mission.
Selvin Chavez, known around the clique as Flash, sat behind the wheel during part of the operation while Enrique Portillo, called Turkey or Oso, rode alongside other younger members moving through residential streets. Those crews were not randomly cruising around neighborhoods, either, since prosecutors later explained multiple vehicles moved separately while clique members stayed connected through phone calls during the hunt.
At some point that evening, the crew spotted Kayla Cuevas walking along Stahli Street beside Nisa Mickens, who still had no direct connection to the earlier school disputes involving Sailors clique members. According to later federal court admissions, clique members immediately contacted Alexis Science plus Jairo Funny Science after recognizing Kayla outside near Ray Court, since younger members often wanted approval before carrying out visible killings tied directly to gang reputation or retaliation. After receiving permission, the crew reportedly circled away from the area before returning with baseball bats plus a machete retrieved from another location nearby. Meanwhile, Kayla and Nisa kept walking through Brentwood like countless other evenings before, probably expecting another normal trip home instead of several armed gang members already
moving back toward them. Around 8:00, the vehicles returned toward Stahli Street while nearby residents stayed inside their homes unaware that a murder crew had already entered the block. Prosecutors later explained how clique members jumped from the vehicle carrying bats alongside the machete before rushing directly toward the girls without warning.
Nisa Mickens reportedly took some of the first blows near the street while Kayla attempted to escape toward the backyards behind Ray Court after realizing the attack was not stopping quickly. The crew chased both girls separately through neighboring properties, which later explained why police eventually discovered their bodies in different locations only several hundred feet apart.
As the attack unfolded, residents nearby mostly heard chaos without immediately understanding what actually happened outside beneath the darkness covering Brentwood streets that evening. Some neighbors later described hearing screaming followed by heavy impacts while others noticed suspicious vehicles speeding away from the area shortly before police arrived.
Nisa’s body was discovered first near Stahli Street with severe blunt force injuries alongside devastating machete wounds across her face and head. Kayla Cuevas was not discovered until the next morning after searches located her body behind a house near Ray Court following hours of confusion involving missing person calls plus frantic family searches around Brentwood.
That timing made the murders hit even harder around the neighborhood since September 14th was supposed to become Nisa Mickens’ 16th birthday celebration with relatives and friends. Instead of birthday decorations, police tape covered sections of Brentwood while investigators photographed blood stains, tracked witness statements, plus searched nearby yards for evidence connected to the killings.
Robert Mickens, along with Elizabeth Alvarado Mickens, suddenly found themselves facing detectives outside crime scenes rather than preparing for their daughter’s birthday the following morning. Across another part of Brentwood, Evelyn Rodriguez and Freddy Cuevas struggled to process that Kayla’s long-running school problems had finally exploded into something horrifyingly permanent.
Once news spread, rumors immediately flooded Brentwood faster than confirmed facts ever could during those first chaotic days after the murders. Some students insisted Kayla had specifically been targeted over earlier arguments involving MS-13 associates, while others repeated gossip falsely claiming both girls were involved with gangs themselves.
Family members pushed back hard against those rumors since Nisa had no documented gang affiliation, while Kayla’s relatives argued she simply defended herself repeatedly against intimidation inside school hallways. Around Brentwood High School, fear settled heavily across students who suddenly stopped walking home alone after classes ended, especially once many realized the attackers were teenagers connected directly to local neighborhoods.
The killings changed Brentwood overnight since parents started pulling children from after-school activities, while students avoided certain blocks after dark fearing another crew might roll slowly beside them unexpectedly. Teachers face classrooms filled with frightened teenagers whispering about machetes, kill orders, plus MS-13 members allegedly sitting only rows away during lessons each morning afterward.
Detectives already suspected the murders connected back towards something larger operating across Central Islip and Brentwood, although most residents still viewed the attacks as one isolated explosion tied only to a school conflict. What people did not know yet was that investigators were about to uncover a whole chain of killings connected to the same clique.
After Kayla Cuevas and Nisa Mickens were murdered, fear spread through Brentwood fast enough that many residents stopped speaking openly once police started knocking on doors around Stahli Street. Parents warned children not to repeat hallway gossip outside school, while witnesses avoided detectives entirely after hearing rumors that the Sailors clique members already knew who talked too much.
That silence created serious problems for investigators, since the murders happened inside residential neighborhoods packed with homes, parked vehicles, plus potential witnesses who suddenly claimed they saw nothing useful. The FBI Long Island Gang Task Force had already started connecting the girls murders to several earlier killings tied back to the same MS-13 clique operating around Brentwood and Central Islip.
Federal investigators slowly realized the same names kept appearing around murder scenes, missing persons reports, plus gang intelligence gathered months before Kayla and Nisa were attacked. Detectives tied Oscar Acosta’s killing, Jose Pena-Hernandez’s disappearance, Javier Castillo’s murder, plus DeJuan Stacks beaten back towards Sailors Clique members moving under Alexi Blasty Science and Jairo Funny Science.
Once prosecutors started building a racketeering case, investigators focused heavily on proving those murders were not random explosions of violence, but organized missions approved by clique leadership. That strategy mattered since the gang operated almost like a moving network across Suffolk County where younger members carried out attacks while older figures approved retaliation, assigned weapons, plus controlled discipline.
Around Brentwood High School, fear kept reshaping daily life after the murders while students started treating ordinary routines like survival decisions needing careful thought beforehand. Some teenagers stopped wearing blue clothing, Nike Cortez shoes, Salvadoran jerseys, or anything potentially mistaken for gang symbolism after hearing stories about people getting pressed over random colors.
Parents who once allowed children to walk home after basketball practice suddenly started driving them everywhere, partly through fear of MS-13 retaliation, partly through panic spreading after several teenagers turned up dead during 2016 alone. Those fears became even heavier once stories involving Elena and her abusive boyfriend Carlos around students familiar with MS-13 relationships operating inside Brentwood.
Carlos originally acted charming around Elena before turning possessive enough that clique associates followed her through school hallways, taking pictures whenever she spoke with other boys nearby. After Elena attempted to distance herself from him, threats toward her family escalated while Carlos bragged openly about violence linked to MS-13 members around Brentwood.
During fall 2016, Carlos reportedly kidnapped Elena, held her across isolated locations for months, then controlled nearly every movement while murders connected to the Sailors Clique kept dominating local headlines. That situation reflected a larger reality around Brentwood, D, where many teenagers felt trapped between gang intimidation, weak institutional protection, plus growing mistrust toward immigration authorities entering the area during investigations.
Another teenager named Henry found himself trapped inside that same pressure after previously working around MS-13 circles before deciding cooperation with authorities might become his only path out. Henry reportedly wrote detailed accounts involving machete killings connected to gang operations across Long Island before eventually sharing information leading investigators deeper into the Sailors Clique structure.
His cooperation came with serious consequences since gang members viewed informants like automatic targets while immigration crackdowns during that period also left undocumented teenagers terrified that police contact could destroy entire families. Around Brentwood, many immigrant parents distrusted both gangs plus law enforcement simultaneously, which created neighborhoods where witnesses stayed silent even after horrifying murders happened directly nearby.
That tension grew worse after civil rights complaints accused schools plus investigators of loosely labeling Latino students as gang members based on rumors, clothing choices, social media posts, or friendships rather than actual crimes. Inside Brentwood High, some teenagers feared gang retaliation, while others feared becoming wrongly targeted by authorities searching aggressively for Sailors Clique associates after the murders.
Meanwhile, Rob Mickens, struggling carrying grief after Nisa’s death, also decided to run for the Brentwood school board, the hoping stronger intervention programs could stop other families from ending up beside grave sites, too. As investigators gathered more evidence through informants, surveillance, witness interviews, plus gang intelligence, federal authorities finally prepared coordinated raids targeting Sailors Clique members during March 2017.
Agents moved across Long Island arresting Alexis Saenz, Cyro Saenz, Selvin Chavez, Enrique Portillo, plus several others tied to killings stretching across Brentwood, Central Islip, Freeport, plus nearby communities. During raids involving the Saenz brothers’ residence, authorities recovered guns, knives, machetes, ammunition, plus a sword allegedly connected to the Clique’s operations during the killing spree.
Prosecutors later unsealed a sweeping federal indictment charging members with racketeering, narcotics trafficking, attempted murders, assaults, firearms crimes, plus several murders connected directly to the violence consuming Brentwood during 2016. One detail shook residents particularly hard after arrests became public since investigators revealed some participants involved in Kayla and Nisa’s murders were juveniles still protected legally through sealed identities. That revelation reinforced how young the Sailors Clique had become while Brentwood High School itself continued sitting near the center of recruitment, intimidation, plus retaliation missions tied to MS-13 operations. Families already traumatized by the killings suddenly realized some attackers might have shared classrooms, hallways, or
lunch periods with ordinary students only weeks before the murders happened. Across Brentwood, memorial candles kept burning outside homes while grieving parents watched federal prosecutors slowly expose how deeply the violence had spread throughout local neighborhoods. The arrests slowed the Sailors Clique down, but the story was still not finished for the family standing over those graves.
Years after the murders shook Brentwood, victims’ families finally sat inside federal courtrooms watching several Sailors Clique members admit details connected to killings stretching across Long Island. Jairo Funny Science looked toward relatives seated behind him smiling briefly while parents of murdered teenagers watched from the opposite side carrying completely different memories inside that room.
Jairo eventually pleaded guilty to seven murders including the killings of Kayla Cuevas, Nisa Mickens, Javier Castillo, plus Dequan Stacks, while also admitting involvement in narcotics trafficking tied to MS-13 operations. Enrique Portillo later admitted that Sailors Clique members received permission from Alexi Blasti Science before attacking Kayla and Nisa, which confirmed investigators belief that retaliation missions required approval from clique leadership beforehand. Those hearings reopened horrifying details family spent years trying unsuccessfully to bury, while prosecutors described baseball bats, machetes, wooded graves, plus organized hunts moving through Brentwood during 2016. Rob Mickens emotionally described seeing Nisa’s body inside the
morgue afterward, explaining he could not even hug his daughter properly after the injuries left by the attack near Stahli Street. Alexi Science eventually received a 68-year federal sentence after pleading guilty to racketeering charges involving eight murders tied to the Sailors clique’s killing spree across Suffolk County.
Even while Science apologized inside courtroom years later, many relatives still viewed the sentences like a delayed closure arriving long after Brentwood had already lost too many young lives. Outside those courtrooms, the murders had already transformed into national political ammunition after Donald Trump repeatedly referenced MS-13 violence during speeches connected toward immigration crackdowns.
Trump eventually visited Suffolk County during July 2017. Grieving parents from Brentwood waited, hoping national attention might finally pressure officials into confronting the violence consuming local schools. Later, families including Rob Mickens, Elizabeth Alvarado, Evelyn Rodriguez, plus Freddy Quavas attended the State of the Union.
That attention divided some relatives emotionally since Freddy Quavas supported harsher punishment, including the death penalty, while Rob Mickens publicly stated he believed life imprisonment already represented enough justice without executions.
Meanwhile, Evelyn Rodriguez refused to fade quietly into grief after Kayla’s death while continuing interviews, activism, memorial events, plus legal action against Brentwood school district officials. Evelyn insisted that school administrators ignored repeated complaints involving threats toward Kayla for nearly 2 years before the murders happened in September 2016.
Her lawsuit accused the district of allowing an unsafe atmosphere where gang intimidation grew openly inside school hallways while vulnerable students received little meaningful protection. Even after national media attention slowly faded elsewhere, Evelyn kept returning toward Ray Court and Stahli Street, organizing vigils while pushing aggressively for accountability connected to the girls’ deaths.
Then, September 14th, 2018 arrived exactly 2 years after Kayla and Nissa were murdered, bringing another tragedy directly back toward the same Brentwood streets already scarred by grief. Evelyn Rodriguez returned near Ray Court, organizing a memorial when an argument reportedly started involving flowers, space near the tribute, plus a nearby resident connected to the property.
During that confrontation, an SUV accelerated forward, striking Evelyn before witnesses nearby fully understood what was happening along the street. The mother who spent 2 years publicly fighting for her daughter died on the exact block where Kayla’s body had been discovered. In the end, the murders began with a school argument involving teenagers, although the deeper story stretched across gangs, neglected warnings, immigration fears, violent recruitment, plus neighborhoods already struggling under years of pressure. Brentwood became nationally famous for bloodshed tied to MS-13. Yet, families living there mostly remembered memorial candles, funeral services, plus classmates who never returned home afterwards. Even after arrests, convictions, plus federal sentences slowed the sailors click down, the scars across Brentwood never disappeared completely
from the people forced to live through that era. The neighborhood kept producing memorials faster than it could heal from them.
