Court Overturns Top Murder Conviction in the Killing of 15-Year-Old “Junior” Guzman-Feliz

A New York appeals court overturned the first-degree murder conviction of Jonaiki Martinez Estrella, the gang member who delivered the fatal knife wound to 15-year-old Lesandro “Junior” Guzman-Feliz in a brutal 2018 attack captured on surveillance video.

The March 9, 2023, ruling did not clear Estrella of murder. Instead, the court vacated the first-degree murder conviction while upholding his convictions for second-degree murder, conspiracy and gang assault. The decision meant he would be resentenced rather than remain subject to the original sentence of life in prison without parole.

A Teenager Was Chased Into a Bronx Bodega

On June 20, 2018, Junior was walking through the Bronx when members of the Trinitarios gang allegedly mistook him for a member of a rival group.

The teenager tried to escape by running into a neighborhood bodega. Several attackers followed him inside, where he was beaten before being dragged back onto the street. Members of the group then attacked him with knives and a machete.

Surveillance footage captured the horrifying assault. Court records stated that Estrella held Junior by his sweatshirt and stabbed him in the neck with a large knife. The wound severed his jugular vein and was determined to be the fatal injury.

Why Did the Appeals Court Overturn the Conviction?

The judges focused on the specific legal requirements for first-degree murder under New York law.

For that charge, prosecutors had to establish that the killing involved a course of conduct intended to inflict torture, as defined by the statute, and that the defendant relished or took pleasure in inflicting extreme physical pain.

The appeals court concluded that the evidence did not meet those particular requirements. The fatal stabbing, although deadly, was treated as a single act rather than the required course of conduct. The judges also found insufficient evidence that Estrella took pleasure in causing extreme physical pain during the attack.

The court nevertheless emphasized that the evidence supported his second-degree murder conviction, which remained in place.

The Ruling Did Not End the Case

The decision sparked renewed attention to a case that had deeply affected Junior’s family and shocked the Bronx community.

In May 2025, Estrella was resentenced to 25 years to life in prison for second-degree murder, according to subsequent reporting. Other defendants involved in the killing had also been convicted and sentenced.

The appeals ruling changed the level of Estrella’s murder conviction, but it did not overturn the finding that he was responsible for Junior’s death.
