BOISE, Idaho (AP) — An American Indian leader who in the 1990s helped convince the U.S. Air Force to move a planned bombing range further from his tribe's reservation on the Idaho-Nevada border has died. Shoshone-Paiute Tribal Chairman Terry Gibson died Thursday on the Duck Valley Indian Reservation after suffering a heart attack, his son, Buster Gibson said.

He was 52. Gibson was in his second term as leader of the Shoshone-Paiutes. Two decades ago, the U.S. Air Force sought to create a bombing range not far from the reservation. At a meeting in a Chinese restaurant in Washington, D.C., Gibson helped draw circles on maps showing southern Idaho, targeting more appropriate locations for the range, says a tribal adviser Doug McConnaughey . Before his death, Gibson was working on a casino project near Boise.
