Lesandro "Junior" Guzman-Feliz, 15, was killed in a brutal stabbing last week in the Bronx. (CNN) — A Bronx teenager was dragged from a store by a group of men, repeatedly stabbed on the sidewalk and left to die in a brutal murder that has sparked widespread outrage in the city and beyond, coalescing around the hashtag #JusticeforJunior. A group of men surrounded Lesandro Guzman-Feliz, 15, at a bodega on East 183rd Street Wednesday night, according to surveillance video of the incident released to CNN affiliate WPIX. The suspects grabbed the teen, who went by the name “Junior,” and dragged him along the ground out of the store before fatally stabbing him, the video shows. When the suspects fled, Guzman-Feliz ran to nearby Saint Barnabas Hospital, where he was pronounced dead, the NYPD said. “The stabbing murder of this young man is among the most brutal crimes I’ve seen in my 36yr career,” New York police Chief of Department Terence Monahan said on Twitter, asking for tips on the killing. As outrage grew this week over the teen’s killing, Guzman-Feliz’s face has appeared on the front of the New York Post for three days straight, and celebrities such as Cardi B and Rihanna have joined local New York leaders in the public mourning.

A police source with direct knowledge of the case told CNN that the killers appeared to have mistaken Guzman-Feliz for someone else. A possible case of mistaken identity Eight men have been arrested for his murder so far, NYPD Chief of Detectives Dermot F. Shea said Tuesday. The suspects appear to be members of the Trinitarios street gang, he said. Trinitarios is the largest Dominican gang in the United States and is primarily based in New York and New Jersey, according to the FBI. “We will not tolerate thugs on the streets of the Bronx, whether it’s Trinitarios or any other gang involved in behavior of this sort,” Shea said. The source told CNN that the Trinitarios gang admitted on social media they attacked the wrong person. The source said New York police don’t know at this time why Guzman-Feliz was targeted. Kevin Alvarez, 19, was arrested and charged Sunday with second-degree murder, manslaughter, gang assault and assault. He pleaded not guilty to the charges and was held without bail at his arraignment Monday, a Bronx court official said. Alvarez is also associated with the Trinitarios, the law enforcement source told CNN. Alvarez’s attorney, Manuel Portela, asked the public to wait for the justice process to take its course. “Our role here is to ensure that his constitutional rights are protected throughout the process,” Portela said. “My client’s family’s hearts go out to the parents and the family of the victim.” Six other men between 18 and 24 were arrested Sunday in Paterson, New Jersey, the Passaic County Prosecutor’s Office said. The suspects waived extradition in court on Tuesday and so will be extradited to New York to face the same charges as Alvarez, Bronx District Attorney Darcel Clark said. An eighth defendant was also arrested in the Bronx and is due to be arraigned on those same charges later on Tuesday, Clark said. Guzman-Feliz’s mother praised the arrests but said they were not enough. “It’s good because they have to pay, but I want my son back,” Leandra Feliz, the teenager’s mother, told CNN affiliate WCBS. “If they could give me the life of my son, I’d be happy.” Seth Wenig/AP Giordanis Guerrero cries Monday as he visits a memorial to the slain teen near the site of the stabbing. #JusticeForJunior Police said that Guzman-Feliz was also a member of the New York Police Department’s Explorers program, which gives young adults an introduction to a career in law enforcement, and dreamed of one day joining the NYPD. “He was never going to give up on his dream of being an NYPD detective & WE’LL NEVER GIVE UP ON HIM,” Shea said on Twitter.

Several police officials mourned Guzman-Feliz’s death and posted tributes to him. “The senseless nature of this horrific tragedy hit all of our communities, in every #NYC neighborhood, very hard,” New York Police Commissioner James O’Neill said on Twitter with the hashtag #JusticeForJunior. The New York City Patrolmen’s Benevolent Association posted a tribute to the slain teen on Twitter, saying his “dream of joining the NYPD was cut short by a murderous street gang.” The police union said it will “carry on in his memory, until the streets are safe” for all New Yorkers.
