VERNON, Conn. (WTNH) — The FBI has issued a new warning for all parents in Connecticut. A violent online network is growing, and it has ties to a local teenage girl.

This is a story with national, international and local ties. The extremist group “764” has penetrated one local town in Connecticut.

It was in September 2024 that the arrest of the 17-year-old, who police say made several bombs and swatting threats to schools and places of worship, was first reported.

NewsNation affiliate WTNH heard exclusively from the parents of that Vernon girl, who say they want to warn other families.

764 is an online network trying to promote world chaos, violence and more.

The girl wanted acceptance into 764, where online predators first gain trust and then blackmail young people into capturing violent content to be shared online everywhere.

“Having that victim carve their alias into their body, having that individual commit suicide on the live feed, having that individual kill animals,” Vernon Police Detective Thomas Van Tasel said.

The arrest of the Vernon teen followed a year-long investigation, and the town was faced with threats. According to authorities, the more gore or violence, the better because it raises the participant’s stature within 764.

National partners at ABC News and the investigative unit spoke exclusively with the Vernon girl’s parents. ABC agreed to alter their faces and voices.

“We didn’t raise her to engage in that kind of activity,” they said. “It’s like she was raised to be a law-abiding citizen.”

Their daughter shared pornographic images and even this Barbie doll with 764 carved in the forehead.

“Before it started, she was a child who was on the honor roll. She had a lot of friends. She attended school activities and hung out with a lot of friends in person,” the parents said.

The detective was asked if the girl from Vernon was a victim or a participant.

“Depending on you ask that question to, the answer may be different,” Van Tasel said.

According to her mother, the young girl from Vernon is cooperating with authorities, and she’s receiving therapy, trying to get her life back on track.

Vernon police said to look for signs of self-harm, suicidal thoughts, behavior changes and changes in eating habits.

Officials advise parents to check gaming platforms and phones and to look through for any disturbing content.
