A trio of orphaned cubs made their public debut in late 2010, as they were rescued from the wild after the death of their mother. The sow had killed a camper in Michigan and attacked other humans and thus was killed before she could inflict any more damage. The cubs have settled in to their huge enclosure, and there is also an older male bear that rotates on exhibit.
Thank you Ituri, and that makes perfect sense. The man who was killed by the female grizzly was from Michigan, but the attack did not take place there. I was in too much of a rush!
