Last week, Ralph Yellow, 78, of Tuba City, Arizona, was sentenced by U.S. District Judge Diane J. Humetewa to 20 years in prison, followed by lifetime supervised release. Yellow previously pleaded guilty to one count of Abusive Sexual Contact with a Child.

Yellow admitted that in 2012 or 2013, he knowingly engaged in sexual contact with a six-year-old child. The evidence also showed that Yellow engaged in sexual acts with other children for decades. The crimes took place on the Navajo Nation Indian Reservation, where Yellow is an enrolled tribal member.

The FBI, Navajo Nation Department of Criminal Investigations, and Gallup Police Department conducted the investigation in this case. The United States Attorney’s Office, District of Arizona, Phoenix, handled the prosecution.
