JACKSON, Wyo. (AP) — The trial for a hunter who shot a grizzly bear in Teton County is under way.

Forty-one-year-old Stephen Westmoreland has pleaded not guilty to a misdemeanor charge of illegally taking a grizzly bear last year. The bear was one of three cubs that gained fame in Grand Teton National Park from 2006 to 2008 as their mother raised them near the roadside.

Westmoreland's attorney, David DeFazio, said in opening statements Tuesday that Westmoreland shot the grizzly in self-defense after the bear dropped to all fours and approached him.

Teton County Attorney Steve Weichman has to prove that Westmoreland took the bear without a license.

Wyoming Game and Fish Department officer Bill Long says there's no license for taking a grizzly.
