There have been dead bodies all over the country. How do you know who made them dead? Were you a witness?
i don’t need to be ~ and, in general, dead bodies get disposed of in several ways all of which are reported. http://abcnews.go.com/US/wireStory/profiles-believed-killed-la-policeman-18492253 provides a brief bio on all the victims. I trust there are death certificates and grieving friends and family. Only a nut case would argue that none of these people existed or that they aren’t really dead.
