All 12 men appeared in court Wednesday morning, where they pleaded not guilty.

Bronx Criminal Court was packed with Guzman-Feliz’s family members, including his mother who yelled “murderers” at the suspects, CBS2’s Natalie Duddridge reported.

The last man taken into custody, 25-year-old Luis Cabrera Santos, was extradited from Connecticut and charged Tuesday with murder, manslaughter and gang assault.

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.

Clark said Wednesday the violence was the result of “intra-gang conflict” between the Los Soros sect, allegedly led by Diego Suero, and the Sunset sect.

His death caught national attention after he was dragged out of a Bronx bodega and stabbed with machetes.
