Lawyers for Native American political prisoner Leonard Peltier are pressing a federal judge for immediate and unfettered access to 90,000 pages of documents they say were wrongly withheld during their client’s 1977 trial. U.S. District Judge Donovan Frank said he would rule on the request by the end of next week. It was the latest in a series of legal challenges to Peltier’s conviction in the killings of two FBI agents during a standoff on South Dakota’s Pine Ridge Indian Reservation in 1975. Peltier’s attorneys believe the thousands of pages compiled by the FBI’s Minneapolis field office could contain information about informants and evidence he could use to win his release or a new trial. Peltier has always maintained his innocence.
