"(CNN) - Terrified and huddled in the corner of a classroom, sisters Jaimee and Madi Roeschke were ready to take on the gunman. "One of the students that was with us passed scissors out to everybody," Madi told CNN's "New Day" Monday. "In some of the drills from last year, they taught us to arm ourselves with anything that we could, such as scissors, chairs, any heavy objects, just in case the shooter were to find us." "At a vigil for the victims Sunday night, "I was crying the whole time for Gracie and Dominic," Madi said. She was far from alone. More than 10,000 mourners gathered at the vigil in Santa Clarita, the Los Angeles Sheriff's Department said. Grace's brother, Riley Muehlberger, broke down as he told the crowd about his "gorgeous, radiant, angelic, caring, intelligent and energetic" sister. "I watched you grow more and more every day," he said. "My favorite about you, Gracie, was how funny you were. You were always able to put a smile on my face, and that's one of the things I'll miss the most," he said. "Thank you for being the best sister ever. I wouldn't want anyone else. Until I see you again, I love you, Gracie." The massive crowd also grieved the death of Dominic, who was a member of the school's Junior Reserve Officers' Training Corps (JROTC)."
