Nikolas Cruz, the suspect in the Marjory Stoneman Douglas school shooting, had never been arrested. But it turns out he had a long pattern of disturbing behavior.
These warning signs include 39 visits to his home by police and a fight on Sept. 20, 2016 that got him suspended from school.
On Sept. 28, 2016, Florida’s Department of Children and Family Services visited his home and later released a report in which authorities called Cruz “a vulnerable adult due to mental illness...with depression... who planned to buy a gun.”
Teachers at the school were reportedly warned in an email not to allow him on campus with a backpack, flagging him as a threat.
On Jan. 19, 2017 Cruz was suspended once again for an alleged assault before he was expelled in February. Three days later, he purchased an AR-15, one of at least 10 guns he reportedly had access to.
Then on Sept. 24, 2017, the FBI received a tip from video blogger "Ben the Bondsman" about a disturbing comment from user Nikolas Cruz.
“This comment said I’m going to be a professional school shooter and I knew I couldn’t just ignore that. I screen-shotted the comment and sent it to the appropriate authorities," said Ben Bennight, known as "Ben the Bondsman" on YouTube.
The most recent red flag was a tip to the FBI on Jan. 5 which the agency says detailed “Cruz’s gun ownership, desire to kill people, erratic behavior, and disturbing social media posts, as well as the potential of him conducting a school shooting,” admitting it should have been assessed as a potential threat to life and forwarded to the FBI Miami field office. It was not.
A little over a month later those warnings became reality with 17 people killed.
