(CBS) -- A biology teacher at a junior high school in the small eastern Idaho town of Preston is under investigation after what school officials call a "regrettable circumstance" involving biological specimens.
East Idaho News reports that teacher Robert Crosland fed a puppy to a snapping turtle in front of students.
Superintendent Marc Gee told media outlets the incident happened after school on March 7 during an after-school animal feeding. Gee would reportedly not discuss the animals involved or release any other details.
The Franlin County Sheriff's Office is investigating the teacher after receiving an animal cruelty complaint. KTSU-TV reported that a local animal activist by the name of Jill Parrish filed the police report.
"Allowing children to watch an innocent baby puppy scream because it is being fed to an animal. That is violence. That is not okay," Parrish told the station.
The teacher remains in the classroom pending results of the investigation. In a statement, school officials asked members of the community for their patience and claimed that the teacher had shown care, effort and passion on the job for years.
