Ryan Wesley Aubol, 23, vanished in December 2016 after a brief, troubling series of events that ended on the Interstate 5 Bridge over the Columbia River. On the morning of December 14 he drove from Portland, Oregon, to the Skamania County Sheriff’s Office in Stevenson, Washington, confused and unable to remember his own name. Deputies identified him from his wallet and summoned medical help. Paramedics arrived around noon, but Ryan ran from them and later witnesses reported seeing him jump from the I-5 Bridge into the Columbia River in Portland.

At the time he was described as a white male with red hair and gray eyes, six feet tall and 160 pounds, wearing dark-colored boxer shorts. Despite an extensive search and witness accounts indicating he entered the river, his body has never been recovered and the family has not had definitive closure. The Portland Police Bureau has used witness statements in the investigation, but the lack of physical evidence leaves key questions unanswered.

Did anyone in the area that day see Ryan earlier or have information about where he was coming from before he reached the sheriff’s office?
