High Crash Zone area Yea to Molesworth, Victoria

#1
Just wondering whether anyone contributing to the forum knows anything about the crash that occurred during 2015 on this stretch of road. There was a young mum and at least one child killed when the car the young mum was driving left the road (goodness only knows why) approaching Yea, Victoria. Vehicle came to rest quite a distance from the road after rolling.

The gossip line has it that for this incident (it wasn't an accident) the young mum was texting and was significantly fatigued. Young mum's last text is said to indicate that she was so fatigued she shouldn't be driving.

I'm wondering whether there is any reliable information around to substantiate the gossip.
