Not sure of the truth of this, but a co-worker of mine heard it today on the radio. It was reported that Troy Gentry of the Country music group Montgomery Gentry purchased a tamed retiredcircus Bear for $4,600 and staged a "hunt" where he shot and killed it. The reports I heard was he actually staged it to look like the bear was charging him as he shot it with his bow.
Here is the atricle that I found abou it.
