Suspected Florida high school shooter Nikolas Cruz was so obsessed with his ex-girlfriend that he threatened to kill another teen she was dating after they broke up.
Cruz, 19, in a jealous rage, fought 17-year-old Enea Sabadini, a Marjory Stoneman Douglas High School student, on multiple occasions after learning the teen was in a relationship with his former girlfriend in 2016, BuzzFeed News reported.
“He got upset about that and started sending messages to me on Instagram,” Enea told the site. Cruz demanded Enea stop seeing the girl or else he would “beat him up,” he said.
Dana Craig, a friend of Cruz’s ex-girlfriend who went to a different school, said she knew Cruz had guns and said her friend told her Cruz was abusive toward her. Dana, 16, also described Cruz as being obsessed with her friends.

In September 2016, Cruz fought Enea over the girl and the two were suspended from the school. By December, Enea and Cruz’s ex broke up.
Enea and Dana complained to the school’s head of security about Cruz’s messages and, in 2017, he was expelled. But in August, Cruz kept sending threatening messages to Enea through social media.
“Iam going to f-----g kill you,” Cruz wrote, according to messages Enea provided to BuzzFeed. “Iam going to watch ypu bleed.”
“I jave guns b---h ahahahahah,” he continued. “Iam going to shoot you dead.” He also sent him a photo of his rifles and a black Velcro vest.
Months later, Cruz gunned down 17 students and faculty members with an AR-15 rifle at his former school on Feb. 14. He’s been charged with 17 counts of premeditated murder. On Friday, the FBI admitted it failed to act on tips it received that the student was dangerous.
