A Broward Sheriff's Office report says 18-year-old Zachary Cruz was arrested Monday afternoon at Marjory Stoneman Douglas High School and charged with trespassing.
The report says the teen was found riding his skateboard at the school though he had received prior warnings from school officials to stay away from the campus. The report adds that Zachary Cruz told the arresting deputy that he was there to "reflect on the school shooting and to soak it in."
His 19-year-old brother, Nikolas Cruz, faces 17 first-degree murder charges in connection with the Feb. 14 shooting.
Jail records didn't immediately list an attorney for Zachary Cruz.
