Presumedly Dead Man Returns

I hate stories like these. A police officer went out canoeing five years ago, disappears, is presumed dead (he was married with 3 children), and then shows up last week in a police station in England. The article ends with a sad quotation from his wife who was left never knowing how to deal with her grief of losing him five years ago, since no body ever was found. The newspapers will report the first part of this story, and then we'll never get the followup to it, in which we actually learn where the hell he has actually been these last five years. Did he go into hiding? Does he have amnesia? Damnit, I need to know!
