Here is the link to the story of the official account of the attack , if it will link : https://trib.com/lifestyles/recreat...5913d2a-4889-5fa9-89d8-e44562b06717.html

Temps in that part of the state have been pretty consistently down into the 20's at night in the mountains. The meat should have been ok unless gut shot. I wonder if he shot it too close to dark and therefore they had to give up the search due to darkness. That guide wouldn't have taken a hunter looking for an elk in grizz country after dark. He would have gone back early morning to look.
We got to know Jon Stephens, GW and one official in on the sow take, 3 years ago on a bison hunt in Jackson. He and the husband have mutual friends and acquaintances in G&F.He's a stand up guy. He made sure we had bear spray for both the husband's hunt and mine the next year. He also recommended a large caliber handgun as backup, if competent with it, for the non hunting companion(spouse).

Hunting the bears may or may not help with the attack situation but at least some aggressive bears would have been targeted to get out of the population. G&F was more than willing to be involved in helping grizzly hunters locate older non breeding boars and problem bears.
We have many friends who hunt the outer edge of the grizzly range, they always have more than a couple of folks along for a pack out or field dressing. They hunt close enough together that when a shot is heard they can check in and be available for lookout services. Maybe a little paranoid, but they have been safe while having had minor bear encounters.
