I hate to be morbid about this, but are there any members here in the Laval, PQ area? Its a terrible tradgedy in any case and my prayers go out to all the families involved. However I'm asking because in the Toronto Sun today in one picture I can see under the big slab of concrete that fell on to the highway is a very distinct 17" wheel of a Mazda '6. That's all that's left of the car that's discernible. If I can find a web photo, I'l post the link.
