Was this in an any bull unit in NE Washington? Are you sure they didn't come back for the spike? Like others, I would have tried to talk to the guys to see if they were bad dudes or just some average guys that made some bad decisions and needed some education. I personally would have also went and tried to recover the spike if they didn't come back for it just to ensure the meat wasn't wasted.
Problem is in this state people think trespassing is not that big of a deal. Hunters that don't follow up on game they shot at is uncalled for. Shooting 13 times at animals seems to be just throwing lead out there hoping to hit something, and not doing right by the animal by know what your and guns capabilities are and hunt within those. Just my opinion.
