LOS ANGELES - Former Long Beach school resource officer Eddie Gonzalez was arrested on a murder charge Wednesday in the fatal shooting of 18-year-old Mona Rodriguez, Los Angeles County District Attorney George Gascón announced."It's an unfortunate, unnecessary death that left a 6-month-old without a mother, a family without a daughter, and clearly a tremendous loss to our entire community," Gascón told reporters Wednesday while announcing the charges."We must hold accountable the people we have placed in positions of trust to protect us," Gascón later wrote in a press release. "That is especially true for the armed personnel we traditionally have relied upon to guard our children on their way to and from and at school."Los Angeles County DA.
