Local police made 36 trips to the house of the Florida mass murderer over a six-year period for erratic or violent behavior, Buzzfeed reported, citing dozens of police reports.
However, Nikolas Cruz, who confessed to the massacre of 17 students and adults at a high school in Parkland, Florida, was never arrested until Wednesday.
In September 2016, police responded to the home Cruz shared with his mother, Lynda, and brother, Zachary, because Nikolas had been fighting with his mom.
"He has been cutting his arms, his mother said, to get attention, as he learned it from an ex-girlfriend," Buzzfeed quotes the police report. "He has mentioned in the past that he would like to purchase a firearm."
However, a therapist from Henderson Mental Health, also at the home, deemed that Nikolas Cruz "no threat to anyone or himself at this present time" and everybody "left without incident," Buzzfeed reports.
Nikolas and Zachary suffered from mental health issues, according to the reports, which detail repeated incidents of two boys who "threw items," were "out of control," "ran away from home," and fought and argued with their mother and one another, Buzzfeed reported.
Nikolas Cruz eventually would undergo treatment for mental health issues, according to reports, but stopped about a year ago.
