The Washington County Sheriff’s Office has released police reports about the January impaired driving arrest of Circuit Court Judge Donald Letourneau, who was cleared this week of criminal wrongdoing. The reports, disclosed Tuesday in response to a public records request, offer some new details about the incident, which was reviewed by the Multnomah County District Attorney’s Office. Letourneau has been a judge for 21 years in Washington County. The district attorney’s office Tuesday released its charging decision, which stated prosecutors could not prove beyond a reasonable doubt that Letourneau, 63, was driving impaired.
