Well, that report clears up what happened as much as is humanly possible.

Ms. Berner was heading east on the same road as the wolves who were heading west. The report concludes that the curvature of the road and the vegetation prevented her from seeing the wolves (and vice versa). It suggests it's possible the wolves could have been aware of her presence due to smell (they were heading into the wind), but that their encounter also could have been a surprise on both sides. The evidence does not indicate she was stalked from behind but that they encountered each other head on.

It did find it likely she was listening to an music player, but did not find it to be a contributing factor; it says that between the naturally silent movement of wolves and the winds reported that night, she wouldn't have heard them in any case.

It does suggest that fact that she was out running & alone combined with her small stature could have been contributing factors to the initial attack.

It's also possible she fled when confronted by the wolves (either immediately or after being met with aggressive behaviour) which could have elicited a predatory response by the wolves, but there wasn't enough evidence to know if that was the case or not. They really don't know what her initial reaction to the wolves was.

It also found the wolves were healthy and there was no evidence they were acting defensively, that they had been habituated to people, that they were being attracted by food, or that they were suffering from starvation or severe hunger.

The report also linked to a Living With Wolves page which gives the following advice of what do do in the (rare) event you are faced with aggressive wolves. In part, it says:
  • Don’t run, but act aggressively stepping toward the wolf and yelling or clapping your hands if it tries to approach.
  • Do not turn your back toward an aggressive wolf, but continue to stare directly at it. If you are with a companion and more than one wolf is present, place yourselves back to back and slowly move away from the wolves.
  • Retreat slowly while facing the wolf and act aggressively.
  • Stand your ground if a wolf attacks you and fight with any means possible (use sticks, rocks, ski poles, fishing rods or whatever you can find).
  • Use air horns or other noisemakers.
  • Use bear spray or firearms if necessary.
  • Climb a tree if necessary; wolves cannot climb trees.
