Two armed robberies occurred back to back in the city of Brockton, Massachusetts by the same suspect. In both robberies the black male subject wearing a black hooded sweatshirt used a sawed-off double-barrel shotgun. In the convenience store robbery, he actually discharges the weapon when store clerk Kirit Patel hesitated handing over the cash tray. One robbery was at the convenience store and another was at a Dunkin' Donuts.
