Marvin Alvin Clark disappeared from the Tigard, Oregon area when he took a "motor stage" to Portland to presumably visit his daughter. He never arrived at her residence, and he was reported missing. He was partially paralyzed on his right side and was said to have a halting gait. Clark had lived in Tigard for approximately 15 years; he was also the old town marshall from Linnton, Oregon and knew the area above St. Helens Highway very well.
