As medical examiners painstakingly piece together the identities and lives of the 30 people known killed when a mudslide wiped out a small Washington community, one mystery troubles them.
One set of remains does not fit with the description on the missing persons list, which, as of Thursday, includes 17 people.
The medical examiners know it is a male, but his remains give no clue as to who he was, or who might be looking for him.
They can't even identify his age range, and at this point, gold teeth are all they have to go on.
The mystery underscores the tedious process of identifying remains more than a week after the March 22 landslide that broke off a steep hill, roared across the North Fork of the Stillaguamish River and buried a community at Oso, about 90km north of Seattle.

Like the homes, the cars and the other parts of people's lives swept away by the torrent of mud, some bodies are in pieces.
Norman Thiersch, the Snohomish County Medical Examiner, said the goal of the team - made up of medical examiners, detectives, dentists and others - is to make sure there's no doubt as to the identities of the victims.
"This is not television," he said.
"These are methodical, painstaking processes we go through."
Although the identities of 28 of the 30 confirmed dead have been determined, officials have so far released the names of only 27.
Other names are expected to be released by the end of the week.
