You know, everybody's wondering what happened in that circumstance, but we have to leave it to the police and the medical personnel to do that determination."

Len Webber, MLA, Calgary-Foothills:

"While there are not a lot of details available at this time, my thoughts and prayers are with the victims of the horrific tragedy. It touches our community so deeply and especially when you consider just how very young the victims were.

I am hopeful that the investigating officers will be able to keep us all informed as this develops. I have not had time to even process what happened or what will need to happen in the next coming hours but will try to find ways to help. One thing I know for certain is that my heart goes immediately to the parents who have suffered such a great loss. We can only try to aid them through this sad time. My heart is breaking for them."
