Hundreds of officers, family and friends gathered Wednesday morning to honor Fernando Arroyos, a Los Angeles police officer fatally shot during an armed robbery attempt last month when he was off-duty.“A young officer who held such promise for this city, who was just beginning his career as a police officer … was suddenly, violently and senselessly taken from us in a murderous act of violence,” Los Angeles Police Department Chief Michel Moore said at Forest Lawn-Hollywood Hills. “May the full weight of our criminal justice system be brought to bear” on the people who killed him.Arroyos attended 42nd Street Elementary School and Audubon Middle School, graduated from Crenshaw High in 2012 and went off to UC Berkeley, where he earned a degree in legal studies. He then returned home to Los Angeles, to pursue his dream of joining the LAPD.
