The death of a 14-year-old Christian County girl has sparked a movement against bullying and suicide. The movement started this month after Miranda Campbell fatally shot herself. Angela Felty is the director of the Elevation Teen Center in Hopkinsville. She says she started the movement with help from youths who attend the center. She says the Miranda Campbell Challenge has a Facebook page and had more than 1,000 "likes" from users just a few days after being set up. Felty and Campbell's father say the teen was bullied because she was bisexual. Hopkinsville High School principal Demetria Choice says she was not aware of any bullying in the classroom, where she says Campbell was well-liked.
