Law enforcement officers in western Wyoming say the driver who struck and killed a famous grizzly bear south of Grand Teton National Park was not speeding and the bear's death was an accident

Grizzly bear 399, who got her name through a research number assignment in 2001, had a yearling cub with her when she was hit on a highway in Snake River Canyon south of Jackson, authorities said. The cub's whereabouts are unknown, but there's no evidence to suggest that it was injured.
