An independent investigation has spotlighted what one reviewer called an "alarming" pattern of grand jury refusals in Tillamook County, leaving crime victims and law enforcement frustrated and District Attorney Aubrey Olson facing tough questions as she campaigns for re-election. County leaders and local detectives say the findings point to basic breakdowns in case preparation and communication that they want addressed quickly.
Investigator Katie Suver detailed what she described as an alarming number of times grand juries declined to indict on cases brought by the DA's office. Her review, more than 200 pages long, found that at least six cases were dropped after grand juries refused to indict between 2023 and 2025, according to The Oregonian/OregonLive.
"Our victims deserve more than that," a sheriff's lieutenant told investigators, according to the report. Detectives and victim advocates described missed chances to bring in medical or other corroborating witnesses before grand juries. Most of the flagged cases involved domestic violence or other personal-violence allegations, including a 2023 incident in which a woman suffered a concussion and needed multiple staples after being hit with a bat. That case was later dropped after a grand jury declined to indict, the outlet reported. The Oregonian/OregonLive
County Report And The Board Response
The Tillamook County Board of Commissioners released a summary of the independent probe and said investigators reviewed more than 50 complaints, including seven formal complaints filed in September 2025. Of those, 35 specific concerns were deemed founded, though the county concluded there was no civil or criminal wrongdoing. The summary, reproduced by local outlet Tillamook County Pioneer, also cited "deficient charging, preparation and trial practices" and weaknesses in victim engagement that officials say they intend to fix.
Prosecutor's Office: Policy And Process
Olson's office issued a brief written statement saying the DA's office "is committed to providing excellent legal representation" and that prosecutors maintain a high bar for proving cases beyond a reasonable doubt. The county's own DA policy manual, updated March 9, 2026, emphasizes that charging decisions rest with the elected district attorney and sets out procedures for how and when evidence should be submitted to the office. County officials pointed to those rules when describing friction between law enforcement and prosecutors. DA policy manual
Why Grand Jury Refusals Matter
In Oregon, grand juries serve as the gatekeepers for felony indictments. State law requires that grand jury testimony be recorded and puts the responsibility on prosecutors to ensure the proceedings are captured. When a grand jury returns a "no true bill," those recordings and notes generally are not released, which limits outside review of why jurors declined to indict. That legal structure, outlined in ORS Chapter 132, is one reason investigators and law enforcement leaders have pushed for clearer documentation and tighter coordination before cases ever reach the grand jury.

What Comes Next
The county board says it plans to work with Olson and her team to address the report's findings. Olson, elected in 2022 and now seeking another term, has pushed back and filed a notice of intent to sue the county, arguing that the investigation damaged her reputation and health. For now, local leaders say they are focusing on nuts-and-bolts changes: faster communication between detectives and prosecutors, clearer evidentiary checklists for cases headed to the grand jury, and stronger victim engagement so that serious allegations reach jurors with the corroborating testimony they need to make a call.
