Federal Warrant Issued for 1980s 'Mountain Man' The U.S. attorney's office in Montana has filed federal drug and weapons charges against one of the notorious "mountain men," a father and-son duo convicted in kidnapping a world class athlete in 1984, killing a would-be rescuer and eluding authorities for months. An indictment unsealed Wednesday alleges Dan Nichols and two other men were involved in a statewide marijuana distribution ring that netted nearly $1.8 million. Federal marshals are searching for Nichols. Authorities issued a warrant for Nichols' arrest last month for failing to appear on state drug charges filed last summer. His father, Don Nichols, convicted of killing a man who tried to rescue former U.S. biathlon star Kari Swenson, remains in prison for the crimes. He has a parole hearing this month.
