Montana Fish, Wildlife, and Parks Department Spokesman Ron Aasheim told KTVQ-TV in Billings that the agency is investigating the allegations.
He says the Department is looking into anything that might help explain why the grizzly bear attacked the campers last week near Cooke City.
48-year-old Kevin Kammer of Grand Rapids, Michigan, was killed, and two other people, a woman from Canada, and a man from Colorado, were injured in the nighttime attacks at the Soda Butte campground.
The female bear was euthanized and a necropsy done. Wildlife biologists say the bear was underweight but not starving.
Her three cubs were moved to a zoo in Billings.
