The teenager repeatedly said “I’m going to kill you” as she first stabbed assistant head Ms Elias, and again when she attacked a pupil, the court heard.
School teacher Ms Hopkin tried to intervene to help Ms Elias, but was stabbed in her neck, back, legs and arm.
Two other teachers tried to calm the girl after she stabbed Ms Elias and Ms Hopkin, but she “rushed passed them”, and went on to stab a fellow pupil multiple times.
Prosecution barrister William Hughes KC described it as a “stand-off” where the teenager moved to another part of the school, and attacked the pupil saying she was going to kill them.
The teenager was said to have initially approached Ms Hopkin and Ms Elias insisting she wanted to go into the hall after being asked to leave by Ms Elias.
The assistant head recalled the girl looking at her with “sinister eyes” and playing with something in her pocket, said Mr Hughes.
When Ms Elias asked her what was in her pocket, the girl pulled out a blade, which belonged to her father and kept in his fishing equipment, the jury heard.
