The Jefferson County sheriff’s race has been shadowed for weeks by a state-level investigation into challenger Tyler Anderson, and the timeline is now tightening in a way that could shape the outcome of the election — and whatever comes after it.

On Thursday, May 21, the Oregon Department of Public Safety Standards and Training’s (DPSST) Police Policy Committee is scheduled to vote on whether misconduct and dishonesty allegations against Anderson rise to the level of a formal certification action. If the committee finds violations, it will likely recommend that the full DPSST board act on Anderson’s credentials — potentially stripping him of the ability to legally serve as a law enforcement officer in Oregon.

The Allegations

Anderson, a former Jefferson County Sheriff’s Office deputy with roughly a decade of service, was fired by incumbent Sheriff Jason Pollock in 2025 following an internal investigation. According to documents obtained through a public records request by Oregon Public Broadcasting, the termination alleged that Anderson was “untruthful” on multiple occasions. Specific findings included:

  • An improper relationship with a confidential informant
  • Omitting a prior termination from an Idaho law enforcement agency on his employment application
  • Failing to disclose prior drug use during the hiring process

Following termination, both the Jefferson County District Attorney and Crook County District Attorney added Anderson to their Brady lists — a designation that bars prosecutors from calling an officer to testify because of credibility concerns.

Anderson’s Response

Anderson has pushed back hard against the characterizations, saying the investigation and subsequent actions were politically motivated. He told OPB that he did experiment with cocaine, marijuana, and mushrooms as a college freshman but says he never distributed them. He denies most other allegations and has filed a tort claim notice against Jefferson County, threatening litigation for wrongful termination, First Amendment violations, and defamation.

“I want to share with the community the stuff I’m going to do to help them,” Anderson said in a recent interview. “And by them seeing my past and seeing what I’ve been through, I hope it just opens their eyes to things that are happening.”

What Certification Means for Voters

Under Oregon law, an elected sheriff must hold valid law enforcement certification within one year of taking office. A dishonesty finding by the DPSST board could result in a permanent ban from Oregon law enforcement — meaning that even if Anderson wins Tuesday’s primary, he could eventually be barred from serving.

Misconduct findings (as opposed to dishonesty) typically result in suspensions ranging from three to 10 years.

The situation mirrors a 2024 case in neighboring Deschutes County, where a similar DPSST probe led to an elected sheriff’s resignation.

Pollock’s Position

Sheriff Pollock, in an email to OPB, said: “I do not agree with the characterization that this matter was politically or personally motivated,” pointing to the third-party investigator his department hired, the independent reviews by two district attorneys, and the ongoing state probe as evidence the process followed proper channels.

Voters in Jefferson County will decide the sheriff’s primary on May 19. The DPSST hearing follows on May 21.
