Terrible and tragic. The poor children!
At the risk of sounding heartless. I do not think they are altogether “poor children”. These parents are quite likely the type who would have raised some really screwed up kids. They probably are getting the biggest break of their life, not withstanding that they have to live with the way their parents died. But, I would offer up my prayers that a loving set of well-balanced people get the privilege of raising these children.
