Memorial service for Jeffrey Gunderson

The family and friends of Jeffrey Gunderson, who’s been missing since 2008, are holding a memorial service for him tomorrow. Little information is available in this case; it seems like the guy just vanished into thin air. It says in the article that he was declared legally dead this past March, less than two years after his disappearance. I’m surprised they were able to do that so soon. There doesn’t seem to be any hard evidence that Gunderson is dead, although his family and his longtime girlfriend are convinced of that.
