SPOKANE — Two police sergeants are under investigation after an 18-year-old Washington State University student claimed she was sexually assaulted by a law enforcement officer.

One of the sergeants works for the Pullman Police Department, the other for the WSU Police Department. Officials from both agencies confirmed Wednesday that the sergeants are on paid administrative leave. The Washington State Patrol is conducting a criminal inquiry, and internal investigations may follow.

“We take the allegation seriously,” Pullman police Chief Gary Jenkins said. “We’re fully cooperating with the Washington State Patrol in their investigation.”

Details of the student’s allegation were not immediately available Wednesday, and it wasn’t clear if she had specified which sergeant allegedly assaulted her.

A search warrant filed Monday in Spokane County Superior Court indicates both sergeants made contact with the student after she was out drinking on the night of March 30. The warrant lists a potential charge of “custodial sexual misconduct in the first degree.”
