JERSEY CITY, N.J. — Frederico Bruno, 19, was arraigned for aggravated assault after the brutal beating of his ex-girlfriend, her roommate and her three-month old son. Bruno allegedly hid in his girlfriend's apartment, and attacked the trio when they entered, shoving his girlfriend and their three-month old child against an air conditioner so hard the pair fell out of a third-story window. Bruno is facing multiple charges, including attempted murder. FiOS1's Christie Duffy reports.
