SADDLE BROOK, N.J. -- An eighth-grader from Saddle Brook was joking when he posted a comment on a YouTube video that prompted a K-9 search and additional police presence at a local grade school, said authorities who tracked him down.
The youngster "cried his eyes out" when confronted with the discovery, Police Chief Robert Kugler told Daily Voice on Wednesday, adding that no complaints were being filed.
"I think everybody learned their lesson," the chief said.
Detective Johnny Tritto found the youngster after obtaining a subpoena.
"The trail led straight to him," said Kugler, who told Daily Voice on Monday that his investigator was zeroing in on the boy. said.
"Our assessment is that it was never intended to be a real threat but rather a more joking like comment," the chief said.
"Our local school district administrators have been so advised and they shall render their own appropriate response and adjudication of the matter and to the juvenile involved," he added.
Kugler repeated his plea for parents to be aware of their young children's online practices.
It began when the Franklin Elementary School boy posted a video of himself sitting in his bedroom offering tips on gaming.
Someone who knew his first name responded Sunday night by threatening the youngster in the video's comments thread.
"You better not go to school [tomorrow]," the poster wrote. "I'm going to kill you."
Emojis of cannonball bombs, knives and other weapons were attached to the post, followed by "jk" (as in: "just kidding").
The boy, in turn, told his parents, who called school officials.
They quickly summoned police.
"School officials and law enforcement immediately took steps to ensure the well-being and security of the students and school environment," Kugler told Daily Voice.
Police officers and Bergen County Sheriff's K-9s swept the building Sunday night to be sure. Kugler also assigned additional patrols on Monday.
Meanwhile, Interim Schools Supt. Anthony Riscica alerted parents.
The boy's video was removed, as well.
Classes resumed on Monday without incident, although an undisclosed number of parents apparently kept their children home for the day.
Kugler said he was glad the boy and his parents moved quickly. However, the fact that a child under 13 was posting videos alone in his bedroom disturbed him.
"It's an issue of Internet safety," the chief said.
"In today's society, everybody has a social media presence," Kugler said. "The rules governing YouTube, just like other social media sites like Facebook, prohibit those under 18 from having registered accounts -- although a 13-year-old can sign up with a parent's permission.
"If you have minor children, I'd urge you to please go over the rules with them," the chief told Daily Voice, in a message to parents. "Please be aware of what they're posting and how they're posting it.
"Just as important as any threat, either credible or not -- even more important, in fact -- is the responsibility of parents and guardians to extensively and constantly monitor their minor children's presence on the Internet.
"Otherwise, our vulnerable children have the potential to be exploited or worse by unknown predators lurking in the shadows of their computer screens," the chief said.
