Nicholas Turning Bear, III, was convicted by a jury of five counts of aggravated sexual abuse of his son and daughter, in violation of 18 U.S.C. §§ 1153, 2241(c), and 2246(2). Mr. Turning Bear's son, N.T.B., was between the ages of four and six during the period over which the offenses were alleged to have occurred, and his daughter, M.T.B., was between the ages of one and three during this time. The government's case rested largely on statements that the two children made during the course of the investigation and at trial. Mr. Turning Bear made no incriminating admissions, and there was no eyewitness testimony from third parties. A physical examination of M.T.B. revealed some evidence that was consistent with, but did not necessarily indicate, sexual abuse. Much of the government's case thus hinged on the credibility of the two alleged victims.
