Juan Pedro Sierra, 52, was last heard from in mid‑August 2019 while traveling through Oregon toward Washington State. Sierra, of Hispanic descent with reddish‑brown hair and a mustache, led a transient lifestyle and was known to ride freight trains, which complicated efforts to reconstruct his movements. The last confirmed location was Stanfield, Oregon, in Umatilla County.

In November 2019 a backpack and several personal items belonging to Sierra were found near the railroad tracks in Stanfield. The backpack held his cell phone, wallet, identification, and sleeping bag. Those belongings being left behind raised concern that his disappearance may not have been voluntary. The Stanfield Police Department opened an investigation but has found few leads, and the exact date he went missing remains unclear.

If anyone saw Juan in mid‑2019 around Stanfield or along the rail routes he traveled, does the community have information that could fill the gaps in his last known movements?
