Carolyn Kaster/AP Florida shooter Nikolas Cruz had become so erratic and mentally unstable in 2016 that officials had recommended he be committed for a mental health evaluation. Cruz had written "kill" in one of his notebooks, drank gasoline, and had begun hurting himself over a year before the shooting, according to documents obtained by the AP. Such a commitment would have likely stopped him from being able to obtain the weapon he used in the shooting at Marjory Stoneman Douglas high school last month. The person who pushed for his commitment was the deputy who later caught flack for not doing enough to stop the shooting. MIAMI (AP) — Officials were so concerned about the mental stability of the student accused of last month's Florida school massacre that they decided he should be forcibly committed. But the recommendation was never acted upon.See the rest of the story at Business InsiderNOW WATCH: Henry Blodget: Will arming teachers with guns help stop school shootings?See Also:Authorities just released surveillance video showing what happened outside the Florida high school during the shootingA judge entered a not guilty plea for the suspected Florida shooter during his arraignmentProsecutors will seek the death penalty for Florida shooting suspect Nikolas CruzSEE ALSO: Authorities just released surveillance video showing what happened outside the Florida high school during the shooting DON'T MISS: Students across the country protested Wednesday to support victims of gun violence — here are the most incredible photos from the National Walkout Day
