Police say the individual fire 8 rounds killing a 20-year-old male from Brooklyn. A bullet also struck a 12-year-old boy in his left shoulder - he’s at an area hospital. Two 17-year-olds were also hit.

An argument allegedly unfolded, and shouting was followed by running and people crying.

Assailant went west into Queens.

50-60 people were there including minors and young kids.
