Alfonso Chadder Cotton, 50, was last seen on December 9, 2013, in Lake Oswego, Oregon, after sharing a meal with a friend who later recalled he seemed depressed and was acting strangely. The next day Cotton’s wallet and identification were found near the Burnside Bridge in Portland, prompting a missing person investigation.

A blue 2002 Mazda MPV minivan belonging to Cotton was later located after being left at a 205 gas station for about two weeks and subsequently towed as a private party impound. The Lake Oswego Police Department searched and processed the vehicle but found no significant leads to account for his movements after December 9.

The circumstances of Cotton’s disappearance remain unresolved, with the personal effects near the bridge and his friend’s report of depression among the few known details. Does anyone have information about Cotton’s last known movements or where he might have gone after that dinner?
