Three people were seriously injured after a argument turned violent. A man was seen wearing shorts that reveled his nutsack and was openly laughed at and joked upon by onlookers. The man became enraged and pulled out what happened to be a mini Draco style machine gun and started firing. 3 people were injured with non life threatening injures and are in area hospitals in stable condition. The suspect was last seen running west down Belmont Ave wearing a G-unit tee-shirt cut off bleached ripped Hoochie man shorts and some grey and white Fubu sandles.
