Florida shooting suspect Nikolas Cruz: Guns, depression

He had been getting treatment at a mental health clinic and then stopped. He was expelled from school for discipline problems. Many of his acquaintances had cut ties in part because of his strange Instagram posts and reports that he liked shooting animals. His father died a few years ago. His mother, reportedly the only person with whom he was close, died around Thanksgiving.

Finally, Nikolas Cruz, 19, had a fascination with guns. He owned an AR-15 assault rifle.

Too few facts are established about the life of Nikolas Cruz to say, with fairness, what might have been done versus what wasn’t done to prevent the mass shooting Wednesday at Marjory Stoneman Douglas High School.
