How were at least 15 warning signs missed for Nikolas Cruz?
" 'I'm going to be a professional school shooter'
"Nikolas Cruz left a comment on a YouTube video back in September using his own name that simply read: 'I'm going to be a professional school shooter' "
Was banned from carrying a backpack
Jim Gard, a math teacher, who had Cruz in his class last year, said he believes the school sent out an email warning teachers he shouldn't be allowed on campus with a backpack.
'There were problems with him last year threatening students and I guess he was asked to leave campus'.
9. Expelled for fighting
The deeply troubled 'loner' was expelled last year for 'fighting over his ex-girlfriend' with her new boyfriend.
10. Abusive to his ex-girlfriend
Students claim the gunman was abusive to his girlfriend
11. Stalked another girl
Mr Gard also claimed that he was taken with another student 'to the point of stalking her', while another student who claims to have been friends with Cruz said he had to cut him off because he started 'going after' and 'threatening' a female friend of his.
12. Peeping Tom
Neighbor Christine Rosburgh said she, and all the other neighbors, were terrified of the teen who would bang his head against a cement wall if his legal guardians tried to send him to school.
She also claims she caught him peeking in her window and when she confronted him, he said he was looking for golf balls.
'I said, "This isn't the golf course".
13. Stopped his mental health treatment
Cruz had been getting treatment at a mental health clinic, but stopped about a year ago and dropped off the radar. He was showing signs of depression.
Broward County Mayor Beam Furr said: 'It wasn't like there wasn't concern for him. We try to keep out eyes out on those kids who aren't connected... In this case, we didn't find a way to connect with this kid.'
14. Possible fetal alcohol syndrome
Natalie Brassard, a program director at the non-profit FASCETS, which works with FASD children, said some of Cruz's characteristics 'suggest that he might have been living with an invisible brain-based condition - it could have been FASD or many others.'
Conditions of FASD can range from mild to severe but can include learning disabilities, intellectual disability or low IQ, poor reasoning and judgment and a host of other issues.
15. Orphaned
Cruz's adoptive mother, Lynda Cruz, 68, died of pneumonia in November last year. She was one of the only people that was remotely close to Cruz. His adoptive father Roger Cruz died of a heart attack several years ago. "
He should have been institutionalized.
