Seven of the eight men charged in the fatal stabbing of a Bronx teenager last month appeared in court Monday, as court officials said they were determining if any suspects will appear before a grand jury.

Some attorneys for the suspects have already declined their right to do so.

Suspects Jose Muniz, Jose Tavarez, Jonaiki Martinez-Estrella, Daniel Fernandez, Manuel Rivera, and Antonio Hernandez-Santiago face a slew of charges, including murder, gang assault, and manslaughter.

The other two suspects, 19-year-old Kevin Alvarez and 23-year-old Elvin Garcia, have both pleaded not guilty on murder and manslaughter charges.

Police say 15-year-old Lesandro "Junior" Guzman-Feliz was dragged out of a bodega in the Belmont section of the Bronx by suspected gang members and slashed in the neck with a machete on June 20. The 15-year-old was pronounced dead at a local hospital. It is believed to be a case of mistaken identity.

The killing of Guzman-Feliz has sparked outrage nationwide on social media, with the hashtag #JusticeForJunior being picked up around the country.

The 15-year-old was a member of the NYPD Explorers Program and had dreams of becoming a detective.

Speaking at an NYPD graduation ceremony Monday, Mayor Bill de Blasio spoke about the impact of the teenager's death on the city.

"His life was cut short so brutally by a gang that knew no decency, no morality," the mayor said. "We will remember Junior, we will remember his goodness, we will remember what he hoped to achieve and we will tell his story to others to inspire them to take his place."

All eight defendants have entered not guilty pleas. They are due back in court on July 16.
