Mass Florida Killer Nikolas Cruz got violent AFTER he was ditched by his girlfriend, it has emerged.
Cruz, 19, shot dead 17 people at Marjory Stoneman Douglas High School and injured dozens more.
In the months leading up to the shooting, Cruz sent a series of threatening messages to 17-year-old Enea Sabadini 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."
"I'm going to watch you bleed.'
Sabadini also alleges that Cruz made several hateful racial slurs and homophobic slurs against him via text by calling him a 'fag**' and 'ni**er'.
"You underground hispanic wall jumper, ill will f***ing destroy you," he also wrote.
In another message, Cruz wrote: "You have no idea what I'm capable of' alongside a photo of a collection of weapons.
Sabadini said he started dating Cruz's ex shortly after they broke up in August 2016.
Other messages accused Sabadini of stealing the girlfriend although she does not want to be identified.
Sabadini said he ended the relationship with Cruz's former girlfriend in December 2016. The most recent threatening messages from Cruz were sent several months later in August 2017.
"He got upset about that and started sending messages to me on Instagram," Sabadini said.
The teen said Cruz also picked two fights with him in September 2016 - one of which happened on a sidewalk outside the school, while the other happened during lunch in the courtyard.
He claims Cruz charged at him during the second fight, part of which was captured on video, and Sabadini said he ended up punching him several times in the face they were both suspended over the incident.
Sabadini alleges he and several other students reported Cruz's social media messages and other threatening behavior to the school.
Cruz had already been expelled from the school when the messages were sent but Sabadini claims he doesn't know what led to his dismissal.
Several reports have surfaced about Cruz violent behavior prior to the shootings.
His mother died in November and his father died years ago.
Florida's Department of Children and Families investigated when
Cruz posted a video on the social media network Snapchat showing him cutting his arms in 2016.
