CBC is reporting that one of the kids was kept on life support until matches could be found for him to donate his organs to six people. Apparently he had signed his organ-donor card as soon as he turned 21.
Without wishing to sound maudlin or glib, some players give their all in overtime. We love the sport itself, to be sure. But often we also love what the sport brings out in people.
Pictures of the accident scene have been few and limited (at least in the sites I've looked at and footage I've seen). However, the intersection appears to have been the prototypic Saskatchewan landscape: flat, square, and unobstructed (i.e., it wasn't any sort of blind corner with limited visibility). I've only driven across that magnificent province a few times, but it struck me plenty of times that one could often drive along those ruler-flat/straight highways for long distances without anyone in front or behind. If your wheels are decently aligned, and the road in good shape, very tempting to take your eyes off the road and tend to something else. The dispersion of the transport truck's load suggests high velocity at impact. So, while the investigation is expected to take a while (as it should), it would not surprise me that the outcome attributes "human error" as the principle cause, rather than anything mechanical.
But that's a mere guess. I'll wait with others for the investigation report.
