As Jefferson County voters prepare to cast ballots in the May 19 primary, a cloud of legal and professional uncertainty continues to hang over sheriff candidate Tyler Anderson, whose law enforcement certification is scheduled for a state review just two days after Election Day.
Anderson, a former Jefferson County Sheriff's Office deputy who was fired in April 2025, faces a Department of Public Safety Standards and Training (DPSST) certification review on May 21. The outcome of that hearing could result in the revocation of his police certification — a credential legally required to serve as sheriff in Oregon.
The Brady List and What It Means
In July 2025, acting Jefferson County District Attorney Steven Leriche added Anderson to the Brady List, a disclosure that prosecutors across Oregon use to flag officers whose credibility may be compromised in court. Once on the list, law enforcement officers cannot ethically be called as witnesses in criminal cases.
The DA's letter cited findings from a March 2025 sheriff's office internal investigation and noted that three different law enforcement agencies have made findings of untruthfulness or dishonesty against Anderson — including the Parma, Idaho Police Department (where Anderson was terminated in 2004), the Oregon State Police, and the Jefferson County Sheriff's Office.
Among the central allegations: Anderson did not disclose his prior employment and termination in Parma, Idaho on subsequent law enforcement job applications with the Madras Police Department and Jefferson County. His application to the Madras Police Department indicated his interest in law enforcement began in 2008 — making no mention of the Idaho position.
Allegations of an Informant Relationship and Deleted Messages
The 2025 investigation also surfaced questions about Anderson's relationship with a subject of a criminal investigation. He was placed on administrative leave in October 2024 amid an inquiry into what the investigation described as an inappropriate relationship with a purported informant. Messages between Anderson's personal phone and the subject were found in phone records. Anderson denied sending them, but acknowledged he had deleted a large number of messages — including full conversations — before sitting down with two FBI special agents.
Anderson's Response
Anderson has not withdrawn from the race. He disputes the characterization of the allegations and draws a sharp distinction between his situation and that of former Deschutes County Sheriff Kent Vanderkamp, who resigned after being placed on the Brady List for false testimony in criminal cases.
"I've never lied on the stand, I've never lied in police reports. I've never treated the public disrespectfully," Anderson said.
Anderson said that if his certifications are revoked, his planned undersheriff could serve in the interim while he pursues recertification. He also said he and his attorneys hope to overturn the Brady List listing once the county has a new district attorney.
What Voters Need to Know
In Oregon, a sheriff must hold a valid law enforcement certification or obtain recertification within one year of taking office. The DPSST review on May 21 will determine whether Anderson's certifications are revoked. Should he win in November without resolving his certification status, the county could face significant legal and administrative challenges.
Incumbent Sheriff Jason Pollock is running for reelection on his departmental record. Ballots for the May 19 primary are due by 8 p.m. that evening at official drop boxes; mailed ballots must be postmarked by May 19 and received within seven days.
