The race for Jefferson County Sheriff is heading toward November’s general election with a major legal cloud hanging over challenger Tyler Anderson. On May 21, Oregon’s Department of Public Safety Standards and Training (DPSST) Police Policy Committee voted to recommend that Anderson’s law enforcement certifications be revoked for life — a decision that, if upheld, could legally bar him from serving as sheriff even if voters elect him.

What Led Here

Anderson, 17-year law enforcement veteran and former Jefferson County Sheriff’s Office deputy, was fired in April 2025 following an internal investigation into a series of alleged ethical violations:

  • Omitting a prior termination from a volunteer position with the Parma, Idaho Police Department on job applications to Jefferson County
  • Allegedly deleting text message conversations with a confidential informant
  • Disclosing to colleagues that he had previously used cocaine and helped package drugs while in college

Anderson has disputed many of the findings. He told the DPSST committee he passed a polygraph regarding the deletion of informant texts and said the Idaho employment information was “an oversight,” not intentional deception. “I would not risk my career over something so minor,” he told the committee.

DPSST investigators confirmed his Idaho employment, and the committee voted to recommend permanent revocation of his police and corrections certifications.

Brady List and the DA’s Office

Following his termination, both the Jefferson County and Crook County district attorneys placed Anderson on their Brady Lists — rosters of officers whose documented history of dishonesty or misconduct makes them unreliable witnesses in court. Anderson has said he would seek to have the listing overturned “as soon as we get a new DA in there.”

What Happens Next

The committee’s recommendation now goes to DPSST’s full 26-member board, which is scheduled to take up Anderson’s case at its July 21 meeting. If the board votes to revoke his credentials, Anderson has said he will pursue an appeal through an administrative law judge — a process that could take more than six months.

Oregon state law requires that a county sheriff hold valid law enforcement certification within one year of taking office. Anderson’s attorneys argue that an ongoing appeal would preserve his standing in the meantime.

“We are looking forward to a trial with an administrative judge and feel confident we will win,” Anderson said after the May vote. “This will not affect my campaign for sheriff.”

Pollock vs. Anderson in November

Because only two candidates filed for the sheriff’s race, no primary election was held. Incumbent Sheriff Jason Pollock and Anderson will meet directly in the November general election. Pollock has served as Jefferson County’s top law enforcement officer since 2022. Anderson contends that Pollock targeted him for termination because Anderson did not support Pollock’s 2022 campaign for office.

Voters will have the final word in November. The July 21 DPSST board meeting will be a critical milestone to watch before then.
