Two Sequoyah Middle School students accused of poisoning their teacher’s coffee have pleaded not guilty in King County Juvenile Court to misdemeanor assault.

The two were arrested Monday and expelled from school.

Prosecutors say they put a vomit-inducing syrup ipecac in their teacher’s cup because one boy was angry at having been sent to the office.

The 39-year-old teacher from Auburn felt ill. She drove herself to St. Francis Hospital in Federal Way, where she was treated and released.

At Friday’s hearing, the judge released the 14-year-old from detention and placed him on home electronic monitoring. The judge put the 13-year-old under his parents’ supervision.

If convicted, the boys could face up to 30 days in detention.

Two boys allegedly poured the syrup-type substance into their teacher’s coffee mug during first-period class last Monday. Shortly after drinking some of the coffee the teacher felt ill and asked another teacher to take over her class.

The boys told other students, and the incident eventually made its way to school security officers. The boys were detained and the Sheriff’s Office was called.

Sequoyah is located in unincorporated King County at 3425 S. 360th St. It is in the Federal Way School District.

Introducing a noxious substance with the intent to commit bodily harm falls under the Assault 2nd statute, a Class B felony. Syrup of ipecac is an emetic (an agent used to cause vomiting) made from the dried root of a plant called ipecacuanha, which is grown in Brazil.
