Both chelsea bombs used Christmas Lights for bombing. And one of the bombs had a label on it for tannerite. That Pressure Cooker bomb was described as being extremely heavy, containing shrapnel to maximize injuries. T determine who could be behind it, the the way youre able to describe it the. Reporter thats right. This could be the work of a serial bomber. Some investigators believer it took more than one person to pull this off. Ray kelly here. You ran nypd for many years.
