Gangbanger convicted in mistaken identity murder of NYC teen found dead in prison as victim’s mom says he ‘deserved it’

One of the cowardly thugs who viciously beat 15-year-old Lesandro “Junior” Guzman-Feliz in a Bronx bodega was found dead at an upstate prison, according to sources and the victim’s mom.

Jonaiki Martinez-Estrella, 31, was found dead at the Coxsackie Correctional Facility in upstate New York while serving a 25-years-to-life sentence in the senseless and deadly 2018 gang assault, sources said.

“He deserved it,” Leandra Feliz, the slain teen’s mom told The Post Sunday. “It’s not going to bring my son back. It doesn’t help the damage he did to me. It doesn’t help the damage he did to my family.

“When you use your life to be a gang member it’s only going to go one of two ways,” she said. “Either going to jail or you’re gong to the cemetery. He went [to[ both. That’s the way life works.”

The vicious mistaken-identity attack shocked the Big Apple after Martiez-Estrella and other members of the Trinitarios gang chased the teen into a Bronx bodega, where they slashed Guzman-Feliz with knives and machetes and beat him to death.

Martinez-Estrella — who was condemned to life in prison without parole in the brutal, caught-on-camera slaying — was re-sentenced on the lesser second-degree murder conviction, for which he faced up to 25 years to life behind bars, an appellate court ruled.

The “extremely heinous” June 20, 2018, machete and knife killing “clearly depicted” Martinez Estrella delivering the fatal slash to Guzman-Feliz’s neck, the Appellate Division, First Department, the ruling said.

Still, the appellate judges found that prosecutors failed to meet the high bar for proving first-degree murder in Martinez Estrella’s case — and he was instead sentenced on the lesser crime.

But in the end the convicted killer ended up with a death sentence — although authorities have not revealed the circumstances surrounding the gangbanger’s death.

Officials at the state Department of Corrections and Community Supervision did not respond to requests for comment on Sunday.

“He is only getting a small taste, a small part of what he did to me,” the slain teen’s mom said as she headed to church services. “He killed an innocent kid outside in the street.

“Him being a 31-year-old that threw his life away to being a gang. He got what he deserved.”
