A 20-year-old college student and musician was injured by an errant bullet fired from the apartment next door into her bedroom this week. Daria Tolokonnikova, who lives with her grandmother in downtown San Diego, was sitting on her bed studying just before 7 p.m. PT (10 p.m. ET) Tuesday when without warning she was knocked out of bed and collapsed onto the floor, bleeding from the back of her head.
