 South Dakota Public Broadcasting's Lee Strupinger has more. Nick Tilson is the president and CEO of Indian Collective. He was one of two witnesses who testified in favor of Peltier's release. Peltier is serving two life sentences in federal prison after being convicted for taking part in a fatal shootout between American Indian Movement members and FBI agents on the Pine Ridge Reservation in 1975. Tilson says the fight for Peltier's release is an uphill battle, but he says he left the parole hearing with a little hope.
