Lead #3Why would a partially paralyzed 69-year-old man with a halting gait undertake this journey, and did his daughter confirm she was expecting him?
Marvin Alvin Clark, a 69-year-old man, disappeared on October 30, 1926, while traveling by motor stage from Tigard, Oregon to Portland to visit his daughter—he never arrived at her residence. Clark was partially paralyzed on his right side with a halting gait, making him vulnerable and distinctive. Despite being a former town marshal familiar with the area, his disappearance remains unexplained nearly a century later, and any information about his journey or whereabouts could help solve this historical missing person case.
