Clarence "Curly Bear" Wagner, an American Indian historian who pressed for repatriation of ancestral remains to tribes, has died. He was 64. Wagner died of cancer Thursday at a Browning hospital on the Blackfeet Indian Reservation, said his cousin Walter Lamar. A cultural director for the Blackfeet Tribe, Wagner shared his culture through his travels in the United States and Europe. However, he always considered the Blackfeet Reservation his home, Lamar said.
