So far, 13 people have been arrested in the murder of Lesandro “Junior” Guzman-Feliz.

On June 20th, Junior was dragged out of a Belmont bodega and murder by several alleged gang members in what investigators say was a deadly case of mistaken identity.

The NYPD says the suspects are members of the Trinitarios gang and wrongly targeted Guzman-Feliz, who police say had no connection to gang activity. He was in the NYPD’s Explorers program for aspiring young officers.
