The shooter used a AR-15 semi-automatic rifle during the crime.
The suspect was taken to the hospital for minor injuries before being taken to the Broward County sheriff's office.
Cruz was a former student of the school but was reportedly asked to leave late last spring after threatening students. The sheriff confirmed Cruz was asked to leaving due to "disciplinary issues."
"We were told last year that he wasn't allowed on campus with a backpack on him," math teacher Jim Gard told The Miami Herald. "There were problems with him last year threatening students, and I guess he was asked to leave campus."
Two Instagram accounts reportedly belonging to Cruz had shared numerous photos of guns, knives and other weapons in recent months.
The Broward County Sheriff's Department and the FBI are currently investigating the crime scene.
