Former student Nikolas de Jesus Cruz, 19, entered Marjory Stoneman Douglas High School in Parkland armed with an assault rifle and began shooting on Wednesday
Traumatized students said that once they heard reports of a mass shooting at the school they knew it would be Cruz, while one teacher said he had been identified as a potential threat to his classmates last year.
Matthew Walker, a 17-year-old student at the school, told WFOR-TV that all his classmates 'knew it was going to be him'.
'A lot of people were saying it was going to be him,' he said.
'A lot of kids threw jokes around saying that he was going to be the one to shoot up the school. It turns out that everyone predicted it. That's crazy.'
'He was going class to class just shooting at random kids,' he said.
'Everything he posts (on social media) is about weapons. It's sick.'
Math teacher Jim Gard, who taught Cruz last year, told the Miami Herald: 'We were told last year that he wasn't allowed on campus with a backpack on him. There were problems with him last year threatening students and I guess he was asked to leave campus.'
Police described the gunman as a student and member of the U.S. Army Junior Reserve Officers' Training Corps program. Nikolas de Jesus Cruz, 19, is pictured being taken into custody
