FORT LAUDERDALE, Fla. (AP) — Panic and fear gripped another Florida school Friday when a gunman who carried a shotgun in a guitar case opened fire, wounding one student before he was taken into custody on a day planned for a national classroom walkout to protest gun violence, authorities said. It happened Friday morning at Forest High School, which was put on lockdown, the Marion County Sheriff's Office reported. The wounded student, a 17-year-old boy, was taken to a local hospital for treatment of a non-life threatening injury to his ankle.
