Jonaiki Martinez-Estrella, a convicted gang member recently resentenced in the murder of Lesandro “Junior” Guzman Feliz, has died in prison. He was 31 years old.

Documents released by the Department of Corrections and Community Supervision listed him as deceased. No details about his death have been provided.

News 12 reached out to DOCC but has not yet heard back.

Martinez-Estrella serving a 25 years to life with the possibility of parole for a second-degree murder charge.

The new sentencing came after the New York State Supreme Court tossed the first-degree murder conviction and wrote that prosecutors did not prove an essential element of the crime - that the defendant inflicted torture on Junior.

On the night of June 20, 2018, Lesandro 'Junior' Guzman-Feliz was fatally attacked outside a Bronx bodega. The 15-year-old was chased down the street, dragged out of the Belmont bodega where he sought refuge, and stabbed and slashed multiple times by his attackers, one of which used a machete. The entire attack was caught on surveillance video.
