I think there was doubt about whether the deceased was cursing & running in protest over his loose dogs being shot at and to protect them, or that the dogs were attacking and the owner was joining in the attack.

I think this is all sad. I suspect the dogs were just running around & ran upon the hiking teacher who got scared. I think leashes on the dogs would have prevented this.

The trailhead is not remote. It is in the rural, small community of Pine, or at least right adjacent to it's boundaries and just off the highway.
