A teenager accused of killing 17 people at a Florida high school was reportedly investigated by police and state officials as far back as 2016 after slashing his arm in a social media video, and saying he wanted to buy a gun, but authorities determined he was receiving sufficient support.
Nikolas Cruz, 19, is charged with committing multiple murders on Wednesday at the Marjory Stoneman Douglas High School in Parkland, a Miami suburb. More than a dozen people also were wounded in the deadliest shooting at a US high school.
More vigils and funerals were scheduled for this weekend in and around Parkland. Two gun shows and a rally calling for the firearm safety legislation also were due to be held nearby.
According to a report by the South Florida Sun Sentinel, a video of Cruz cutting his arm posted on Snapchat in September 2016 raised concerns among law enforcement and at the Florida Department of Children and Family Services.
"Mr Cruz stated he plans to go out and buy a gun. It is unknown what he is buying the gun for," said a report written by department officials after investigators interviewed the teenager, according to the South Florida Sun Sentinel.
Investigators ultimately decided that Cruz, then 18, was receiving enough support from mental health professionals and from his school, and that any risk in his case was low.
Representatives for the Department of Children and Family Services did not respond to requests from comment.
FBI's failings
On Friday (US time), the Federal Bureau of Investigation admitted it failed to investigate a warning this year that Cruz possessed a gun and the desire to kill.
A person described as close to Cruz called an FBI tip line on January 5 to report concerns about him, according to the FBI. That information was not forwarded to the FBI's Miami office, in what agency officials called a breakdown in protocol.
The disclosure spread angry disbelief among Parkland residents and led Florida's Republican Governor Rick Scott to call for FBI director Christopher Wray to resign.
"We have spoken with victims and families and deeply regret the additional pain this causes all those affected by this horrific tragedy," Mr Wray said in a statement on Friday.
US Attorney General Jeff Sessions has ordered a review of FBI procedures following the shooting, in which 14 students and three school staff members died.
According to CNN, Cruz posted disparaging comments about Jews, African-Americans and gays in a private chat group on the social media network Instagram.
"I think I am going to kill people," Cruz wrote in the group, according to CNN, which also quoted an unnamed law enforcement source as saying the suspect bought at least five guns in the past year.
Broward County Sheriff Scott Israel has said that his office had received about 20 "calls for service" in the past few years regarding Cruz and would scrutinise all of them to see if they were handled properly.
