BILLINGS, Mont. - Montana officials say they will not challenge a wildlife company's refusal to kill a captive 500-pound brown bear involved in the fatal mauling of an animal trainer.

Fish and Wildlife Administrator Dave Risley said Tuesday agency officials don't believe they have authority to enforce their request that the bear be killed.

But Risley says the bear will always be suspect, and is likely to be permanently barred from leaving the Bozeman-area property of Animals of Montana.

The company charges fees to film and photograph animals.

A second bear was shot on the scene after Benjamin Cloutier, formerly of York Haven, was killed Nov. 4 in the bears' pen.

Animal advocates filed a complaint with federal safety officials Tuesday alleging Cloutier's death was avoidable.

Head trainer Demetri Price says Animals of Montana's practices are safe.
