The incident happened earlier this week, but deputies learned about it Thursday and arrested the girls Friday, the sheriff's office said.
A 12-year-old student sought revenge after she was disciplined by her teacher, Jayne Morgan, 52, Monday, deputies said.
Morgan sent the girl to the principal’s office, because she said the student dumped glue into another student’s backpack and was suspected of stealing a laptop.
That’s what sparked the girl to bring hot crushed red pepper flakes to school the following day to pour in Morgan's soda, deputies said.
Morgan’s throat became hot and scratchy after drinking the soda, and she started to feel a shortness of breath, a report said. Morgan poured the soda into a cup and noticed the red pepper flakes.
The teacher suffered stomach pains and a sore throat for the rest of the day.
Deputies discovered two other students were involved in the incident.
One girl allegedly dumped the pepper into the can after the other handed her the soda, while the third student distracted Morgan.
Two girls are being charged with poisoning food or water and tampering with consumer products. The other girl is being charged with tampering with consumer products and being a principal to poisoning food or water.
Morgan said she nearly died from an allergic reaction.
She said in a statement, “My students and I are very close. For the sake of education, for the sake of my school, other teachers in the classroom, and for the sake of students themselves, children need to know there is a right and a wrong. This is illegal. I could have died.”
