The world mourned last fall when a beloved Grand Teton National Park grizzly bear was killed by a vehicle. Now, one of her most famous offspring has met the same fate.

Grand Teton National Park has shared in a news release that the body of grizzly bear 1058 was found earlier this week inside the park along Highway 26 east of the Buffalo Fork River. An investigation determined that he’d been hit by a vehicle but was able to reach a patch of willows 125 yards away before dying of his injuries. His remains have been returned to the park’s landscape.

1058, who was 5 years old and in good condition at the time of the vehicle strike, was one of the four cubs reared by grizzly bear 399 in 2020. The popular foursome provided entertainment to wildlife enthusiasts across the globe during the early days of the COVID-19 pandemic.

Their mother was already quite popular at the time and affectionately known as the Queen of the Tetons. Well into her 20s, she’d been photographed and filmed by visitors and park staff for years at that point.

Unfortunately, last October, 399 was also killed by a vehicle. Her crash occurred outside of the park south of Jackson, Wyoming, on Highway 26/89. She was 28 years old and still raising a yearling, who was not believed to have been harmed.

At the time of her death, U.S. Fish and Wildlife Service Grizzly Bear Recovery Coordinator Hilary Cooley said, “People from around the world have followed grizzly bear 399 for several decades. At 28 years old, she was the oldest known reproducing female grizzly bear in the Greater Yellowstone Ecosystem.”

According to Grand Teton, 399 was among 51 grizzly bears killed by vehicles in the Greater Yellowstone Ecosystem between 2009 and 2024.
