A Washington kindergarten teacher who sent a 5-year-old student home with a bag of feces tucked in his backpack has been formally reprimanded.

A West Valley School District official warned teacher Sue Graham in a letter that similar behavior in the future will result in disciplinary action, including termination.

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

The boy was moved out of Graham's classroom after the incident.

The May letter was released Thursday in response to a public disclosure request from KIMA-TV. The district had previously
said "appropriate action" was taken against the longtime teacher.
