The 417-pound (189 kilogram) male grizzly bear broke her neck and severed her spine, an autopsy found, causing instantaneous death. A nearly empty can of bear spray that appeared to have been recently deployed was found under her tent, officials said.

This 2020 photo provided by the Wyoming Game and Fish Department shows the worn, mostly toothless jaw of Grizzly 168. – A 34-year-old grizzly bear captured in southwestern Wyoming has been confirmed as the oldest on record in the Yellowstone region, Wyoming wildlife officials said. Grizzly bear 168 was captured last summer after it preyed on calves in the Upper Green River Basin area. Biologists could tell grizzly 168 was responsible after examining the calves. Grizzly 168 has outlived all females documented within the Greater Yellowstone Ecosystem by four years, and female grizzly bears tend to live longer, officials said.
