A 15-year-old girl was gang-raped, beaten, and robbed by six to ten men ranging in age from 15 to their early 20s on Saturday in Richmond, California after leaving her high school homecoming dance. More appallingly, police say, over the course of two hours, as many as two dozen people witnessed the crime, but didn't interfere. As the girl left the dance to meet her father, who was picking her up, a classmate asked her to join a group drinking in the courtyard. The girl was drunk by the time the assault started. As they raped her, some men laughed and took photos, police said. The girl was found, semiconscious, under a picnic table an hour after the dance ended. So far, three suspects have been arrested in the attacks.
