A 5-year-old bear born to grizzly bear royalty was fatally struck by a vehicle in Grand Teton National Park, officials said.

The bear was one of four cubs that emerged in May 2020 with their mother, Grizzly No. 399, who was often called the world's most famous grizzly bear.

Grizzly bear 399 was hit and killed by a car on Highway 26/89 in Snake River Canyon south of Jackson, Wyoming, in October, McClatchy News previously reported. The 28-year-old mother grizzly was the oldest known reproducing grizzly bear in the Greater Yellowstone Ecosystem.
