A substitute teacher has been charged in the United States after allegedly making online threats about a potential attack on a school, authorities said.
Hadyn Dollery, 19, was arrested following reports of disturbing messages posted on Discord referencing John Champe High School, located near Washington D.C in US.
According to police, the suspect allegedly shared messages describing violent intentions and claimed to have a “kill list,” prompting concern among authorities. Investigators said a tip-off from a member of the public played a key role in identifying and apprehending the suspect.
Dollery, who worked as a non-licensed substitute teacher during the 2025–26 academic year, was reportedly arrested on school grounds. Following the arrest, the individual was removed from the school district’s substitute teaching roster.
Law enforcement officials confirmed that the suspect has been charged with threats of bodily harm and is currently being held without bond at the Loudoun County Adult Detention Center.
A court appearance has been scheduled for May 26. Authorities have not disclosed further details about the alleged plan, but the case has raised renewed concerns about online threats and school safety, as well as the importance of early reporting of suspicious behaviour.
