Grizzly 399 had a yearling cub with her when she was struck by the vehicle. The cub's whereabouts are unknown, but there is no evidence it was involved.

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.

The man who struck and killed Grizzly 399 while commuting home from Jackson on Tuesday night was driving at around the speed limit of 55 mph, law enforcement officials said
