In all three locations that I read about this event, it was written in a brief, breaking-news format, with plenty of room for revisions and updates as more information is made available.
For the moment, all three were similarly written in a "margarita glass" format. All the vital summary information is at the top in the first paragraph, followed by what chronology officials had available at the time and small supporting details.
I believe for this sort of story, because it will undoubtedly be updated very soon, this formatting style was an ideal choice. There is no need for a great deal of trivial information at this point.
