BILLINGS, Mont. (AP) - Wildlife officials say a grizzly bear has been euthanized after tests determined it was responsible for a triple mauling in a Montana campground.

Montana Fish, Wildlife and Parks spokesman Ron Aasheim said Friday DNA tests determined the sow killed a Michigan man and injured two others in unprovoked attacks in a campground overnight Wednesday.

The bear was euthanized after wildlife officials captured the sow and her three cubs at the Soda Butte Campground five miles from Yellowstone National Park.

A U.S. Fish and Wildlife Service official says the sow's three cubs will be sent to ZooMontana in Billings. Chris Servheen says the zoo and wildlife officials were making arrangements Friday and they hoped the transfer would take place as soon as possible.

Jackie Worstell, executive director of the Billings zoo, said the cubs would join its grizzly exhibit.
