The 16-year-old was shot dead during a daytime brawl on Queens Street Wednesday afternoon, police said.
According to the NYPD, the teenager just got off the bus when he took part in a battle with apparently armed rivals near Jamaica Avenue and 172nd Street in Jamaica.
The suspect, wearing a gray hoodie and a black vest over a mask, blew him with his chest before fleeing east on Liberty Avenue, sources told the Post.
The injured teen stumbles across the street and collapses, and officers find him in a pool of blood.
He rushed to the doctor to the Jamaica Hospital Medical Center, but was unable to save him.
His suspicious murderer has not yet been caught.
The latest youth violence comes a month after a 14-year-old was fatally stabbed on Sunnyside, Queens during a battle involving multiple teens.
