CODY, Wyo. — Wyoming wildlife managers said they are unable to determine what type of bear attacked a Minnesota hiker last weekend, although they suspect it was a grizzly bear

Authorities said 48-year-old Bradley D. Johnson of Plymouth received severe injuries to his arm, shoulder and back when he encountered a bear on Sept. 9 in the Beartooth Mountains near the Wyoming-Montana border.

The Wyoming Game and Fish Department said its investigation found evidence that multiple bears had been in the area where the attack occurred.

Cody Regional Wildlife Supervisor Dan Smith said the investigation indicates that the incident was an unfortunate case of a surprise encounter that occurred at close range and that the bear probably was protecting a food source.
