The bomb threat at Jefferson Elementary School earlier this morning has been cleared, said Pullman School District Superintendent Paul Sturm.

The bomb threat was discovered by a school secretary on the voicemail system. The recording left by what sounded like a young-adult male indicated the school might not be safe, Sturm said.

Strum said students on the premises were then evacuated to Pullman High School while parents were notified of the situation. Parents were advised to wait to bring their children to school until an all-clear was delivered.

Students returned to class around 9:30 a.m. after police and faculty swept the school premises.

Police are investigating who might have left the threatening voicemail.
