The decision not to file criminal charges comes following independent investigations by the Sheriff's Office and the Washington State Patrol into the dust-up between Pacific Mayor Cy Sun and his own police force, said King County sheriff's spokeswoman Cindi West.
Sun was accused of destroying public records, assaulting employees and intimidating a public servant. He was arrested in July when he attempted to enter the City Clerk's office as news photographers captured the action live.
The Pacific police officers were accused of violating police procedures regarding the treatment of individuals in custody.
Following the arrest and allegations, Pacific City Council President Leanne Guier made a formal request to the Sheriff's Office to conduct an independent investigation.
The Sheriff's Office investigated the alleged misconduct by the mayor, and the Washington State Patrol looked into the alleged misconduct by police officers.
Following an extensive investigation, the Sheriff's Office submitted its findings to the King County Prosecutor's Office. After reviewing the investigation, the Prosecutor's Office determined that no charges would be filed due to a lack of evidence that a crime was committed.
The State Patrol also completed its portion of the investigation. After a review by prosecutors, it was determined there is no evidence to justify proceeding with criminal charges against any of the officers.
The decisions follow months of long-simmering tensions between Sun, members of the city council and Sun's opponents who accuse him of abusing power in the small town on the King-Pierce county line.
