Martinez-Estrella’s death was confirmed through prison records, though authorities have not offered further details on what led to his passing.

Just weeks prior to his death, Martinez-Estrella had been resentenced by a Bronx Supreme Court judge to 25 years to life in prison for his role in Junior’s death. The resentencing came after a ruling by the New York Court of Appeals in 2023, which overturned his original first-degree murder conviction. Despite this legal technicality, Martinez-Estrella remained convicted of second-degree murder, gang assault, and conspiracy.

The Murder That Shocked the Nation

On June 20, 2018, Junior Guzman-Feliz became the tragic victim of mistaken identity when he was targeted by 14 men associated with the Trinitarios gang. Surveillance footage and witness statements helped piece together what happened that night. Around 11:40 p.m., Junior was chased into a bodega at East 183rd Street and Bathgate Avenue in the Bronx. There, a group of gang members dragged him out and brutally attacked him.

Martinez-Estrella was identified as the individual who delivered the fatal machete wound to Junior’s neck. After the attack, the bleeding teenager ran toward nearby St. Barnabas Hospital but collapsed on the sidewalk just steps from the entrance. According to investigators, his final words were a plea for water.

He died shortly thereafter, leaving behind devastated family members and a shocked community. He had only gone out to repay a friend $5 a small act of honesty that turned into a fatal mistake.

A Life Cut Short

Lesandro, affectionately known as “Junior,” lived just a block from the bodega where he was attacked. He was described as a kind, funny, and respectful teen who enjoyed playing video games like Fortnite and NBA 2K. He asked his older sister for dating advice and aspired to one day become a detective. In fact, he was an active participant in the NYPD’s Explorer Program, which prepares youth for careers in law enforcement.

His sister, Genesis Collado-Feliz, and his mother, Leandra Guzman, remembered him as a gentle soul with no gang affiliations whatsoever. “All I can say is that he was a good kid,” Genesis said. “He just played PlayStation. He asked me for advice with girls. He was just 15.”

A City Mourns and the World Responds

News of Junior’s murder spread rapidly, thanks in part to graphic video footage that circulated online. Public horror turned into outrage as the city and world learned the details of his death. The hashtag #JusticeForJunior quickly trended on social media platforms, becoming a rallying cry for justice and an end to gang violence.

Candlelight vigils, marches, and balloon releases followed. Communities across New York and beyond united in their grief, demanding accountability for the attackers. In the years since, the NYPD has continued to honor Junior’s memory. In November 2024, officers released balloons to mark the six-year anniversary of his death.

Sentencing and Judicial Reckoning

Ultimately, 14 gang members were charged in connection with the murder. The five men most directly involved in the physical attack, including Martinez-Estrella, were convicted of murder and received long sentences:

Jonaiki Martinez-Estrella: Initially sentenced to life without parole; later resentenced to 25 years to life.

Antonio Rodriguez Hernandez Santiago, Jose Muniz, Elvin Garcia: Each sentenced to 25 years to life.

Manuel Rivera: Sentenced to 23 years to life due to being a minor at the time of the crime.

Prosecutors emphasized Martinez-Estrella’s callousness. On the day of one of his court appearances, a correctional officer discovered a one-inch sharp object hidden in his shoe. Despite telling the judge “I’m sorry” and blaming drugs, alcohol, and gang loyalty, his lack of remorse was evident, according to officials.

The Family’s Endless Grief

For Junior’s family, no sentence could ever truly heal the wound. His mother, Leandra Guzman, delivered a heartbreaking statement in court, declaring, “They killed an innocent child. Of all these men, not a single one of them said, ‘No, no, don’t do it.’ That night, there were two deaths Junior and I, who was left dead inside.”

She described her son as her pride and joy a boy who dreamed of helping protect others. “Please make sure my son’s dreams come true. These killers should never be able to step out of a jail cell. When they killed my son, they took their own lives too.”

Her grief did not stop in the courtroom. A year after Junior’s death, she visited the exact spot where he begged for help. “I feel the same day. It’s nothing passing for me,” she said. “I feel like I’m in the first day.”

Advocating for Change

In the aftermath of the tragedy, Leandra has become a vocal advocate for reform. She pushed for the installation of panic buttons in bodegas to ensure that future attacks could be reported and halted immediately. Additionally, a free summer camp was established in Junior’s honor, serving as both a memorial and a resource for at-risk youth.

Her efforts reflect a desire to channel unbearable loss into meaningful change ensuring that no other family has to endure what hers did.

Closing a Chapter, But Not the Pain

The death of Martinez-Estrella brings a symbolic close to one part of this deeply painful saga. While it may offer a small sense of closure to some, it does not erase the grief or fill the void left by Junior’s absence.

Former NYPD Chief of Detectives Dermot Shea put it best when he said, “I don’t think the family will ever recover in a case like this. It never ends for victims.”

Even as one of Junior’s killers is now gone, the echo of that summer night in 2018 still haunts the hearts of those who loved him. And for many, the call for justice, reform, and remembrance will continue for years to come.
