The suspect in a Florida school shooting was a former student, the sheriff said.
“I don't know why he left, I don't know when he left,” Broward County Sheriff Scott Israel told reporters, but “he was not a current student”.
The unidentified gunmen opened fire both from outside and within the school, Mr Israel said.
The sheriff's office has identified at least 14 casualties and taken the suspect into custody. Mr Israel said the suspect was arrested “without incident” somewhere off campus about an hour after the shooting.
A former teacher told the Miami Herald that he believed the former student was already on the school's radar.
“We were told last year that he wasn’t allowed on campus with a backpack on him,” math teacher Jim Gard told the Herald. “There were problems with him last year threatening students, and I guess he was asked to leave campus.”
