Dan Hargraves, the Pullman Police Department sergeant facing a charge of custodial sexual misconduct in the first degree, resigned from the department Monday.

Pullman Police Chief Gary Jenkins announced Hargraves’ resignation in a news release Thursday. Jenkins also said in the release that Hargraves violated department policy.

“The internal investigation concluded that Hargraves violated a number of Pullman Police Department polices, including involvement in criminal conduct, failure to activate his body-worn camera as required, failure to make proper notifications when transporting a female and improper treatment of persons in custody,” Jenkins wrote in the release.

Hargraves did not submit a statement for the Pullman PD internal investigation, according to the release. Pullman PD and the Washington State Patrol arrested him on Oct. 30 at the PPD station following an independent investigation by the WSP.

The charge comes after an April incident involving a female WSU student. Whitman County Prosecutor Denis Tracy said the charge means Hargraves stands accused of sexual contact with a person in custody in a statement released on the day of his arrest.

“The charge alleges that Officer Hargraves abused his power as a police officer when he detained a young woman for being a minor intoxicated in public, and then engaged in sexual intercourse with her,” Tracy wrote in the statement.

Jenkins also stated that he will be notifying the Washington State Criminal Justice Training Commission that Hargraves will be separated from service because of disqualifying conduct. This will begin the process of decertifying Hargraves as a police officer in Washington.

In a press conference on the day of Hargraves’ arrest, Jenkins said his colleagues were saddened by the news.

“I think our department is in somewhat disbelief and shock,” Jenkins said at the conference. “Some people also feel betrayed.”

Hargraves still faces his felony charge in Whitman County Superior Court. An omnibus hearing is scheduled for 10 a.m. Friday.
