A 28-year-old man shot dead during a fight on a Brooklyn street early Saturday was a member of the violent Trinitarios gang, police sources said.

The victim, whose name was not released, died after being rushed to Jamaica Hospital after the 4 a.m. shooting on Grant Avenue near Fulton Street in Cypress Hills, according to police.

The Trinitarios are the gang blamed for the Bronx mistaken-identity stabbing slay in June of Lesandro “Junior” Guzman-Feliz, 15.

Guzman-Feliz had hoped to be a cop some day.
