The Pullman Police Sergeant accused of sexual assault has resigned as the department finds that he violated multiple policies. Dan Hargraves resigned on Monday the day before he was set to be interviewed by internal investigators. He has been charged with felony custodial sexual misconduct in Whitman County Superior Court.

The Washington State Patrol says that Hargraves instructed an 18 year old female Washington State University student to perform a sex act on him. The alleged assault occurred in late March while the victim was being detained by Hargraves for an alcohol violation.

The Pullman PD’s internal investigation was completed without a statement from Hargraves. It concluded that he violated several department policies including involvement in criminal conduct, failure to activate his body cam, failure to make proper notifications when transporting a female and improper treatment of persons in custody.

Chief Gary Jenkins will submit a notice to the Washington State Criminal Justice Training Commission that Hargraves is no longer a Pullman Police Officer due to “disqualifying conduct.” That notice will begin a process to decertify Hargraves as a Peace Officer in Washington. That decertification is then entered into a national index and is accessible to law enforcement agencies around the country.

Hargraves pleaded not guilty to the felony. He is scheduled to stand trial in January. Hargraves remains out of jail after being released on his own recognizance. He had been on paid administrative leave since early April.
