::::It is quite a stretch to claim that the various crimes over a period of several days are all "the  
 Marathon bombings," since a shooting is not remotely a bombing. A revised title of broader scope would be needed if all this person's and his brother's alleged crime and other actions are to be encompassed in it. That said, if more  info about the brothers and their activities is in the future reported by reliable sources, an article or two articles about them can be spun out in the future.
