COOKIE CITY, Mont. - One man was killed and two people were hurt in a Grizzly bear attack in a Montana campground on Tuesday.

Montana wildlife officials on Thursday identified the man killed in the mauling as Kevin Kammer, 48, of Grand Rapids, Michigan. The other victims, Deb Freele of London, Ontario, and an unidentified male, have been hospitalized in Cody, Wyoming. They are expected to recover.

A mother grizzly and two of three cubs were captured Wednesday evening.  Montana wildlife officials believe she is responsible for the Yellowstone campground attacks.

Fish, Wildlife, and Parks Warden Captain Sam Sheppard said the attacks are highly unusual and predatory.

"She basically targeted the three people and went after them," Sheppard said. "It wasn't like an archery hunter who gets between a sow and her cubs and she responds to protect them."

Officials said the sow will have to be killed, but the fate of her cubs has not been decided yet. It is not likely they will be returned to the wild.
