According to my calculations, that makes a total of 27 accident victims. Were all these people in the minivan, or were some of those injured merely standing on the street nearby? No mention of any explosion, or whether it could have been muffled by the sound of the collision. Perhaps the detonator didn't work. And the presence of a child's dress doesn't necessarily mean there was a little girl present. We haven't heard the other side of this story, and probably never will.
That's one big freakin' van. A Ford Econoline seats 15 max.
