PHOENIX—On July 22, 2014, a federal grand jury returned a four-count indictment against Ross Stetson Tewangoitewa, 67, of Shungopavi Village, Ariz., for aggravated sexual abuse of a minor.

A conviction for aggravated sexual abuse of a minor carries a maximum penalty of life in prison, a $250,000 fine, or both.

An indictment is simply a method by which a person is charged with criminal activity and raises no inference of guilt. An individual is presumed innocent until competent evidence is presented to a jury that establishes guilt beyond a reasonable doubt.

The investigation preceding the indictment was conducted by the Federal Bureau of Investigation and the Bureau of Indian Affairs.
