FORT LAUDERDALE, Fla. -- The father of a teenage football player killed by a lightning strike during a high school football game has filed a lawsuit against the Broward County School Board saying the school did not provide sufficient warning.The school did not use a lightning detection device and failed to provide sufficient warning and evacuation measures, attorney Holly Krulik said in a statement Tuesday.Krulik is representing Julio Noel, whose 15-year-old son Schaffner Noel, was killed in October 2005. Noel was hit in the chest by the lightning and transported to Broward General Medical Center, where he was pronounced dead.Two other students were hospitalized and 10 other students were treated at Monarch High School for cuts, bruises and abrasions. A police officer also was injured in the strike.Witnesses said the faculty already had stopped the junior varsity football game because of thunder, and the students were coming off the field when Noel was struck, authorities said at the time.According to Krulik, the school board had previously decided to stop using handheld detectors because officials decided they were not adequate. After Noel's death, the school board decided to use a new wireless weather alert system, Krulik said.Keith Bromery, a spokesman for Broward County Public Schools, said he had not seen the lawsuit and declined to comment.
