David Byrd-Felker vanished in the cloud forests of Ecuador 10 years ago Sunday.
He was 20, the son of Mike Byrd, who was then a popular professor of philosophy at the University of Wisconsin-Madison, and of Maggie Felker, a nurse. Mike and Maggie look nothing alike. He is dark and curly. She is fair and fine-featured. Somehow, David resembled them both – perhaps because he so fully embodied their distinctive intelligence, humanity and sweetness.
