LYNN -- Twenty-nine Lynn English High School students have been suspended and more could face disciplinary action as the city continues to investigate a fight between two girls that was refereed and videotaped by students, who did nothing to stop it -- even when one girl’s head was slammed into a stone wall. Lynn Mayor Judith Flanagan Kennedy, who is also the chair of the city’s school committee, said all 29 students are also required to do a research paper on the 1964 murder of Catherine “Kitty” Genovese, whose shouts for help went unanswered as she was murdered in New York City.
