LEWISTON, ID — A half-century will soon pass since Patricia “Patty” Otto disappeared from Lewiston, and investigators still do not have a clear answer about what happened to her. August 31, 2026, marks 50 years since the Idaho woman and mother vanished without a trace, according to Project Cold Case.
The case remains among the state’s oldest missing-person investigations, and authorities continue to look for information that could move it forward.
Last Known Details
Otto was 24 years old at the time, married, and the mother of two daughters. Source material cited by Season of Justice says she left her home voluntarily after a reported argument with her husband, and Lewiston was the last known place she was seen.
The city sits near the Washington border and has a population of roughly 35,000, making the disappearance a long-running concern in a relatively small community.
Search For Answers
Advocates say the anniversary is another chance to draw attention to the case and ask for tips from anyone who may know what happened. The public appeal is aimed at helping Idaho detectives find answers for Otto’s family.
The case has lingered for decades without a confirmed resolution, even as it has stayed on the radar of cold-case organizations.
Remains Not Identified
The source notes that human remains were later found in Oregon, not far from where Otto had lived years earlier. Testing did not produce a definitive identification because of the condition of the remains.
Those remains were believed to be similar to those of a woman who may have matched Otto’s physical characteristics, but no confirmed link was established.
