In the days since a group of men hacked, stabbed and slashed a Bronx teen to death outside a Belmont bodega, outrage over the violence has spread online, through the city and beyond.

Activists are using the hashtag #JusticeForJunior to demand the maximum punishment for his suspected killers and an end to gang violence.

As News 12 has reported, the incident's graphic violence circulated widely in surveillance video posted to social media. It shows the attackers dragging 15-year-old Lesandro Guzman-Feliz, also known as Junior, along the ground as he claws helplessly at the brick wall of a bodega. 

Police arrested six suspects in Paterson, New Jersey. Four of them are Bronx residents: Jose Tavarez, 21, Manuel Rivera, 18, Danel Fernandez, 21, and Antonio Hernandez Santiago, 24. Jose Muniz, 21, is from New Jersey, and Jonaiki Martinez-Estrella, 24, is from Freeport, on Long Island.

The NYPD arrested two other suspects in the city: 19-year-old Kevin Alvarez,  and 23-year-old Elvin Garcia. All eight of them face a slew of charges that include murder.

The video shows multiple men stabbing and slicing the teen. Then Guzman-Feliz is shown stumbling -- with blood gushing from his throat -- before heading toward a nearby hospital. Police say he died outside.

According to police sources, the suspected gang members mistook the teen for someone else before killing him.

Investigators say the suspects have ties to the violent Trinitarios gang, which has also been blamed for another violent, public stabbing last week. In that case, a group including suspected gang members chased a boy onto the Bronx River Parkway during rush hour and stabbed him more than a dozen times. He remains hospitalized in critical condition.
