Hard news articles are written so the reader can stop reading at any time, and still come away 
with the whole story. This is very different from an essay, which presumes that the audience will 
stick around to the end, and can therefore build to a finish. There is no need to put a 
"conclusion" on a news story. Each individual reader will "end" the story whenever he or she 
gets bored. A particularly interested reader will keep reading to the end.
