A person close to Nikolas Cruz, the confessed shooter in the Parkland, Florida, school massacre, contacted the FBI on January 5 to report concerns about him, the bureau said in a statement on Friday.
But the bureau did not appropriately follow established protocols in following up on the tip.
“The information was not provided to the Miami Field Office, and no further investigation was conducted at that time,” the statement said.
The stunning admission is sure to raise further questions about whether the FBI could have prevented the shooting at Marjory Stoneman Douglas High School, which left 17 dead.
FBI Director Christopher Wray said the bureau is still investigating what happened.
“We have spoken with victims and families, and deeply regret the additional pain this causes all those affected by this horrific tragedy,” Wray said in the statement. “All of the men and women of the FBI are dedicated to keeping the American people safe, and are relentlessly committed to improving all that we do and how we do it.”
The FBI also was warned in September about a possible school shooting threat from a YouTube user with the same name as Cruz, according to a video blogger.
Ben Bennight, the 36-year-old YouTube video blogger from Mississippi, noticed in September an alarming comment on a video he’d posted. He told CNN he immediately contacted the FBI.
“Im going to be a professional school shooter,” read the comment, left by a user with the name Nikolas Cruz.
