YAKIMA, Wash. — A West Valley kinder-garten teacher has been formally reprimanded for sending a bag of human feces home with a 5-year-old student in April.

Sue Graham, who teaches at Apple Valley Elementary School, was warned in a letter that similar behavior in the future will result in disciplinary action, including termination, Superintendent Peter Ansingh said Thursday.

The May letter was revealed Thursday in response to a public disclosure request from KIMA-TV. The district had previously stated that “appropriate action” was taken against the veteran teacher.

The boy’s father had said his son arrived home in April with a plastic bag of feces and a sticky note that read, “This little turd was found on the floor in my room.”

The student had spent part of the day in Graham’s class and part of the day in a special needs class.

The boy has since been removed from Graham’s classroom.

The boy’s father said he contacted local media after he called and e-mailed school and district officials but got no response about the incident.
