This is the shocking moment Florida school shooter Nikolas Cruz attacks a classmate he accuses of stealing his ex-girlfriend.
Cell phone footage dating back to September 2016 shows Cruz lash out at 17-year-old Enea Sabadiniin in the courtyard of Marjory Stoneman Douglas High School.
The teenage murderer can be seen wearing khakis, a white printed short-sleeved T-shirt and a dark bandana around his neck. At one point Cruz holds Sabadiniin on the ground.
In the months leading up to the shooting, Cruz sent a series of threatening messages to Sabadini on Instagram after he started dating his ex-girlfriend, 'I'm going to f***ing kill you,' Cruz allegedly wrote to Sabadini.
'I am going to shoot you dead.'
Another said: 'I'm going to watch you bleed.'
Sabadini said he started dating Cruz's ex shortly after they broke up in August 2016.
Other messages accused Sabadini of stealing the girlfriend. The ex-girlfriend has said she does not want to be identified.
