Cops said a hero tipster helped expose the suspect’s sinister online posts.

The 19-year-old was reportedly arrested on school grounds.

Dollery allegedly wrote threats that included mass killings, documents obtained by the Loudon Times-Mirror showed.

Documents said the twisted teen, from nearby Chantilly, also claimed to have a hit list.

Dollery worked as a “non-licensed” supply teacher for the 2025-26 school year.

But after the would-be-attacker was thrown behind bars, Dollery was kicked off the district’s list of substitutes.

The suspect was seen smirking in a haunting mugshot.

The teen identifies as a trans woman but was booked as a male and is reportedly being housed alone, WJLA reported.

Dollery was charged with threats of bodily harm.

Police said the teen teacher is being held without bond at the Loudoun County Adult Detention Center.

Dollery will appear in court on May 26.

It comes after a teacher was allegedly stabbed to death by a teen student who was harbouring a grudge against her.

Olesya Baguta, 55, was ambushed and attacked as she arrived for work in April at School No. 5 in Dobryanka, Russia.

Her alleged killer, named as Matvey, was reportedly lying in wait at the school gates before launching his vicious attack.

Olesya died in hospital from knife wounds.

The Russian language and literature teacher was popular with students and was voted Teacher of the Year in 2018.

Frantic efforts were made to save Baguta, who was also vice-principal at the school, with an air ambulance rushing her to hospital.

Governor Dmitry Makhonin said: “Unfortunately, despite all the doctors’ efforts, it was not possible to save her.”

The suspect had made violent threats in the past, but sources said the warnings were “not taken seriously”.
