Gunman Opens Fire At Hospital, Kills Self At School POSTED: 11:57 am EDT May 4, 2006 UPDATED: 12:28 pm EDT May 4, 2006 FERNANDINA BEACH, Fla. -- Three people were shot at a north Florida hospital Thursday by a gunman who then went to an elementary school and shot himself in the parking lot. Police believe the shooting was the result of a domestic dispute. They said a gunman shot and killed a person and injured two others at a hospital north of Jacksonville, and then killed himself at an elementary school. The county sheriff said all four people were related. The incident started just before 10:30 a.m. at Baptist Medical Center-Nassau, where shots were fired and three people were hit. Nassau County Sheriff Tommy Seagraves said the gunman then went on foot about 1Â½ miles to the grounds of Emma Love Hardee Elementary and fatally shot himself in the parking lot. Officials told TV station WJXT that there were no injuries at the elementary school. Nassau County School administrators said the children are safe and being fed lunch. The school remains on a limited lockdown, but children will be released to parents with photo identification. Children who are not picked up will be dismissed at the normal time and buses will run on schedule. Sandra Loper, a teacher's aide at the school, said the students were locked into rooms after a shot was heard. "The front of the school is glass, so I imagine that somebody could have seen it," Loper said. Seagraves said he believes the shootings resulted from a domestic dispute, and a person at the school told WJXT that the gunman was a relative of a teacher at the school.
