Authorities in Eastern Oregon have been seeking public help during Chief Joseph Days to solve the case of Isaac Roberts, who disappeared a year ago during the annual Wallowa County rodeo and celebration.
The 40-year-old took a motorcycle trip from Coeur d'Alene, Idaho, to Joseph, the northeastern Oregon town where he'd graduated from high school in 1990.
Police believe he was killed within 24 hours of arriving. His body has not been found.
Investigators say Roberts was seen leaving a bar about 1:45 a.m., and he and another man made a trip to Lewiston, Idaho, afterward.
Officers have posted bulletins throughout Joseph this week in hopes of developing tips. Roberts' brother, Shiloh, has offered a reward of $25,000 for information.
