A ‘Wall of Grief’ mural marks the spot where a 15-year-old Bronx boy, who wanted to be a detective when he grew up, fell victim last month to a New York City drug gang with a long history of ruthless violence.

The mural pays tribute to Lesandro “Junior” Guzman-Feliz who was killed June 20 by a group of Trinitarios in a crime that sent shockwaves reverberating through the Big Apple and beyond. The murder captured the attention of music stars Rihanna and Cardi B.

But those prosecutors have appear to have created a power struggle pitting one group of Trinitarios against another.

Such acts of brutality don’t surprise Manuel Gomez, a former U.S. army intelligence officer and NYPD cop-turned-private investigator, who said he obtained the video of Lesandro’s last moments and shared it with WPIX-TV, which was the first to report it.

Gomez told Fox News that the Trinitarios have been just as vicious as MS-13 without drawing the same amount of attention. President Trump has singled out the former for its brutality – labeling them “animals” – as part of his crackdown on illegal immigration.
